Don Brookfield, Jr. checks on progress in the New Brookfield Powder Testing Lab Brookfield Engineering has established new Powder Testing Labs in Boston Massachusetts USA, Harlow Essex England (near London), Dresden Germany, Guangzhou China, and Mumbai India. Brookfield developed these labs in response to increasing customer demand for rapid evaluation of powder behavior and flowability. Customer samples are tested using Brookfield's PFT Powder Flow Tester for Flow Function, Wall Friction and Bulk Density as a function of consolidation stresses. Shear cell methodology is the technical approach used to test all customer samples in accordance with ASTM D6128, D6682, and D6773. The testing is completed within 5 business days and the results are emailed to the customer. These reports enable the customer to see actual data which can be used to improve their process by characterizing powders with flow aids, and serve as a reference for future powder formulations. Brookfield offers the first three Powder Sample Tests for free with a nominal charge for additional sample testing. Customers are also given the opportunity to use the PFT at their facility for a one week trial period. See Brookfield's affordable PFT Powder Flow Tester.

BROOKFIELD _ VISCOMETERS / RHEOMETERS

Why measure viscosity?
The ability to gather data on a material's viscosity behavior gives manufacturers an important "product dimension." Knowledge of a material's rheological characteristics is valuable in predicting its pourability, its performance in a dipping or coating operation, or the ease with which it may be handled, processed, or used. The interrelation between rheology and other product dimensions often makes the measurement of viscosity the most sensitive or convenient way of detecting changes in color, density, stability, solids content, and molecular weight.

Why Choose Brookfield?
Ease of use, flexibility, reliable performance and quality of service have made Brookfield Viscometers favorites all over the world. All Brookfield Viscometers are accurate within ±1.0% of the range in use and have a reproducibility within ±0.2%. Test results can be duplicated anywhere in the world when the same model instrument is used.

Falling Ball Viscometer
...Newtonian measurements made simple and easy!
The Brookfield Falling Ball Viscometer uses the simple -- but precise -- Höppler principle to measure the viscosity of Newtonian liquids by measuring the time required for a ball to fall under gravity through a sample-filled tube. Set of six balls to test a wide variety of samples Connection to circulating bath for temperature control of sample Temperature Probe Pivot bearing allows for quick and easy tube rotation for repeat test Model KF40 (shown) variable angle allows for greater viscosity range Model KF30 (also available) fixed angle complies with DIN 53015 Viscosity Range: 0.5 to 70,000 mPa·s (cP) Accuracy: 0.5% to 2.0% (depending on ball used)

How It Works
The Falling Ball Viscometer is based on the measuring principle by Höppler for simple but precise dynamic viscosity measurement of transparent Newtonian fluids. The basic concept is to measure the elapsed time required for the ball to fall under gravity through a sample-filled tube inclined at an angle*. The tube is mounted on a pivot bearing which quickly allows rotation of the tube 180 degrees, thereby allowing a repeat test to run immediately. Three measurements are taken and the average time it takes for the ball to fall is the result. A conversion formula turns the time reading into a final viscosity value. The Falling Ball Viscometer is used for quality control in various industries as well as in academic institutions to illustrate scientific method. The ease of use and straightforward method for recording time measurements ensures meaningful test results.
*Model KF30 has a fixed angle of 80 degrees; Model KF40 can be angled at 50, 60, 70 and 80 degrees.

Ball Set with Case
The Falling Ball Viscometer comes complete with a set of six (6) balls. See Specifications for material construction.

R/S Plus Series Rheometers
TM

for Controlled Rate/Stress Measurement

R/S Plus Series of rheometers represent the best that Brookfield has to offer -- instruments that operate both in controlled shear rate (rpm) and controlled shear stress (torque) modes -- for sophisticated rheological analysis. With automatic data collection and analysis using optional Rheo3000 software, R/S Plus Rheometers offer greater flexibility and features than other high-end rheometers in their class -- at a fraction of the cost. R/S Rheometers have a durable design with rapid bob (spindle) attachment and easyto-clean surfaces for years of trouble-free operation. Increased measurement capabilities range from simple single-point viscosity tests to comprehensive rheological profiling. Evaluate material behavior from initial yield stress through full flow curve response at variable shear rates to relaxation, recovery and creep. The R/S Plus is available in four configurations: coaxial cylinder (Model R/S-CC), cone and plate (Model R/S-CPS), soft solids tester with vane spindles (Model R/S-SST), or portable version (Model RC-1).

Some popular applications include:
ADHESIVES: RS-CPS tests a variety of silicone-based adhesives at temperatures up to 135°C. Advantages include small sample volume (< 2mL), rapid temperature equilibrium with P1 Peltier plate, variable shear rate (to 6000 sec-1) to duplicate conditions for actual adhesive use, quick test time (< 2 min). ADHESIVE INGREDIENTS: RS-CPS with Peltier control excels at rapid QC measurements at defined shear rates. Optional Peltier plate changes temperature much more quickly than bath/circulator. Test throughput increases dramatically. BIOMASS: RS-CC with vane spindle in coax chamber measures biomass fluids used for biofuel production. Easily handles suspended solids and evaluates important flow properties by simulating what happens to the material during pumping in production. CHOCOLATE: RS-CC is instrument of choice for select manufacturers who run 24/7 operations requiring robust, reliable performance. Choice of optional serrated bob (spindle). Conforms to DIN and ISO test methods which quantify yield stress and consistency using Casson analysis. Affordable alternative to higher priced rheometers. DAIRY: RS-CC with double-gap geometry measures low viscosity (<0.1 Pa·s) dairy products ranging from skim milk to thicker creams. GYPSUM: RS-SST is popular choice for measurement of joint compound manufactured by the gypsum industry in accordance with ASTM C474. Small footprint, data display in BU units, and robust design make it ideal for lab and production floor use. PESTICIDES: RS-CC with double-gap geometry measures various low viscosity formulations (0.02 Pa-s) at shear rates up to 2500 sec-1. Provides reliable capability in a busy QC lab measuring dozens of samples each day. PHARMACEUTICAL: RS-CPS with open plate design for easy sample placement accommodates a variety of small sample sizes (< 4mL) and rapid temperature control using the Peltier option (P1). Produces quick profiling of flow behavior, including yield stress and creep, important properties for characterizing ointments. PIGMENT DISPERSIONS: RS-CPS with Peltier (P1) is used by a range of industrial markets, including plastics and paints. Handles broad viscosity range from thin formulations (0.025 Pa·s) to non-flowing pastes. Broad shear rate capability simulates both processing of materials (pumping and mixing) and application of material (brushing and spraying). SAUCES AND SYRUPS: RS-CPS with Peltier (P2) replaces traditional hour-long viscosity tests which measure product from a cooking vessel after it cools to room temperature. Peltier option cools sample to 25°C in less than 1 minute, greatly reducing test time. SLUDGE/SLURRIES: RS-SST with vane spindle geometry measures diverse mixtures with particulate materials ranging in concentration up to 70%.

Rheo3000 Software
for increased R/S data analysis capabilities Enhance your R/S Plus Rheometer
THROUGH PROGRAMMED CONTROL AND DATA ANALYSIS

Your PC can do the detailed data collection and analysis work for you. Rheo3000 allows you to program the R/S Rheometer and control shear stress or shear rate. Data is saved in a SQL database for easy access by multiple users on a network. Use multiple step test programs to create data history and calculate average viscosity or thixotropy. In addition, Rheo3000 provides automated analysis of fluid behavior against user-defined control limit values, resulting in better quality control. Mathematical data processing models included are: Newton, Bingham, Casson, Ostwald, Steiger-Ory, and Herschel-Bulkley.

A traditional flow curve plot with the viscosity functions (shear stress and shear rate) has stress on the Y-axis (dyne/cm2) and shear rate (sec-1) on the X-axis. Shear Stress (dyne/cm2) divided by Shear Rate (sec-1) = Viscosity (in Poise).

A flow curve made with R/S-CC Plus Coaxial Cylinder Rheometer and 25 mm bob. The program ramped shear rate from 0.1 sec-1 to 200 sec-1 over 60 seconds in step one, and from 200 sec-1 to 0.1 sec-1 over 60 seconds in step two. All fluids were pseudoplastic (shear thinning) and slightly thixotropic (time dependent).

A stress ramp with R/S-CC Plus Coaxial Cylinder Rheometer and 25mm bob ramped shear stress from 0 Pa to ~550 Pa over 60 seconds in step 1, and from ~550 Pa to 0 Pa over 60 seconds in step 2. The fluid has a distinct yield value (just over 100 Pa) because in step one there was no viscosity (or shear rate) until the yield point was achieved. Note that on the down ramp (step 2) there were shear rates below 100 Pa so the fluid structure seemed to have been changed by the test.

A temperature/viscosity ramp run with R/S-CPS Plus P1 Rheometer. Temperature was ramped from 25°C to 100°C over 5 minutes. The instrument (using geometry P50; 50 mm flat plate with a gap setting of 0.5 mm) was run at a constant shear rate 100 sec-1.

The difficulty with viscosity measurements of hot melts and liquids at elevated temperatures has been in maintaining accurate temperature control that is consistent from sample to sample so that meaningful data could be obtained. The Brookfield Thermosel solves this problem by providing a stable, precisely controlled sample environment. This, together with the inherent accuracy of the Brookfield Viscometers, is fundamental to the Thermosel System, which produces viscosity measurements that are not only accurate but entirely reproducible. Several factors contribute to the stable environment: Non-fluctuating temperature control Small sample volume and insulated sample chamber which reduces temperature gradients within the sample The rotating spindle, which acts as a built-in stirring device The test procedure is quite straightforward. Once familiar with the system, unskilled operators can easily produce accurate, reproducible data.

Removable Sample Chamber The design of the Small Sample Adapter allows the sample chamber to be easily changed and cleaned without disturbing the set-up of the viscometer or temperature bath. This means that successive measurements can be made under identical conditions. Temperature Control The sample chamber fits into a water jacket so that precise temperature control can be achieved when the Brookfield circulating temperature bath is used. The stirring action of the rotating spindle, plus the small sample volume, helps to keep the temperature gradient across the sample to a minimum. Direct readout of sample temperature is provided using sample chambers with optional embedded RTD sensor connected to the DV-I Prime and DV-II+Pro Viscometers and the DV-III Ultra Rheometer. Working temperature range for the Small Sample Adapter is from 1°C to 100°C. Cylindrical Geometry The Small Sample Adapter's coaxial cylinder geometry provides extremely accurate viscosity measurements at defined shear rates. Disposable Sample Chambers and SC4-27D Spindle Disposable 13R chambers, for hard-to-clean materials, are available in a kit that comes complete with 100 chambers and special-sized water jacket (Part No. SSA-DCU). Additional disposable chambers can be purchased in quantities of 100 (Part No. SC4-13RD-100).

What's Included?
Locating Channel Assembly Spindle (304 s/s) (p46) with universal coupling nut Collar assembly with thumbwheel Water Jacket Chamber Tube Tube End Caps
(package of 6)

Optional Accessories
Closed Tube and Spindle made from 316 s/s

Available with EZ-Lock spindle coupling (p50) The Brookfield Enhanced UL Adapter is used with any standard Brookfield Viscometer and Rheometer to make accurate and reproducible measurements on low viscosity materials. Newtonian and non-Newtonian materials can be measured. It is most commonly used with the LV series instrument (at 60 rpm, these models have a full scale range of 1-10 cP with the UL Adapter). The UL Adapter consists of a precision cylindrical spindle rotating inside an accurately machined tube. Its rheologically correct cylindrical geometry provides extremely accurate viscosity measurements and shear rate determinations. The tube has a removable end cap which allows the open ended tube to be used in a beaker or tank. With the cap in place, the closed tube can be immersed in a temperature bath or used with the ULA-40Y water jacket for precise temperature control. Working temperature range is from 1°C to 100°C.

Why replace your current UL Adapter?
The new design saves a significant amount of time on set up and tear down of equipment. The new spindle with universal connector is easier to thread onto the viscometer. The entire assembly can remain in place between tests with only the chamber being removed to prepare the next sample for testing.

Quick & Easy Design Saves Time
Quick & easy attachment of spindle:

Longer coupling nut for better grip and twist action to connect spindle to viscometer. Redesigned bracket for attaching ULA assembly to viscometer. Provides more clearance for finger grip on coupling nut.

Quick & easy removal of chamber:

Detail of UL Adapter: 1. Locating Channel Assembly, 2. Water Jacket, 3. Chamber Tube, 4. Collar with thumbwheel, 5. Tube End Cap, 6. Spindle with universal coupling

Simply loosen thumbwheel, chamber slides down and out. Permits rapid testing of multiple samples by swapping out chambers. Choice of leaving spindle attached to viscometer or disconnecting spindle and removing it with chamber. Water jacket sleeve remains in place attached to viscometer while chamber and/or spindle only are removed. Saves set up time for the operator.

EZ-Lock Option
Enhanced UL Adapter is available with special EZ-Lock spindle coupling for use on standard Brookfield Viscometers/ Rheometers already equipped with the EZ-Lock feature. (p50)

Unique ULA Assembly Design Provides Multiple Benefits:
Sturdy collar attaches to locating channel assembly which is connected to viscometer pivot cup. Sample chamber is held firmly in place by the collar which provides proper alignment for the spindle rotation within the chamber. Universal coupling nut on spindle ensures firm connection with viscometer and automatic self-centering of spindle in chamber during rotation. Direct immersion of chamber in temperature bath is quick and easy. Water jacket grips slide over collar and operator manually aligns the collar/jacket assembly to allow easy insertion of chamber containing sample to be tested.

Helipath Stand

TM

designed for measurement of non-flowing substances

For viscosity/consistency measurement of gels, pastes, creams, putty, gelatin and other nonflowing substances. A Brookfield Viscometer or Rheometer is mounted on the Helipath drive motor and a T-bar spindle is attached to the viscometer using a special coupling. The drive motor slowly lowers or raises the viscometer so that the T-bar spindle creates a helical path through the test sample thus eliminating the problem of "channeling". Compatible with standard Brookfield Viscometers and DV-III Ultra Rheometers Simple to set up and clean Provides a solution for hard-to-measure materials Complete with drive motor, 6 T-bar spindles with coupling, case, lab stand, rod and base

The Helipath Stand can be used with any standard Brookfield Viscometer model, and is supplied complete with a set of six T-bar spindles and a special coupling.

EZ-Lock Option
Helipath Stand is now available with special EZ-Lock spindle coupling for use on standard Brookfield Viscometers/ Rheometers already equipped with the EZ-Lock feature. (p50)

BROOKFIELD _ TEXTURE ANALYZER

What is texture analysis?
Texture analysis is primarily concerned with measurement of the mechanical properties of a product, often a food product, as they relate to its sensory properties detected by humans. Fifty years of texture research has developed a set of definitions relating the sensory properties of a product to the instrumental properties which can be calculated from the results of a two cycle texture profile analysis test. Texture analyzers perform this test by applying controlled forces to the product and recording its response in the form of force, deformation and time. These graphs show two ways of looking at the data from one 2 cycle Texture Profile Analysis test. The force vs time graph clearly shows the force peak resulting from each compression cycle, while the force vs distance graph better displays the response of the sample to the application and removal of strain.

PARAMETERS1
Hardness

SENSORY DEFINITION
Force required to compress a food between the molars. Defined as force necessary to attain a given deformation. Ratio of the height the sample springs back after the first compression compared to the maximum deformation. Net work invested in the non-recoverable deformations of the first and second chews. The net energy required to chew a SOLID food to the point required for swallowing it. Measurement of how a sample recovers from deformation in relation to speed and forces derived.

INSTRUMENTAL DEFINITION
Peak force of the first compression cycle. P1

Springiness Index Preferred for comparing samples of different lengths Corrected Cohesiveness (PELEG, 1976) Corrected Chewiness

Springiness divided by total deformation.

DS __ DT B1 - B2 _____ A1 - A 2

The ratio of the net work of the second cycle B1 - B2 divided by that of the first cycle A1 - A2. The product of hardness, corrected cohesiveness and springiness index Resilience is the ratio of work returned by the sample as compressive strain is removed (known as recoverable work done A2 ), to the work required for compression (known as hardness work done A1). The negative area for the first bite, representing the work necessary to pull the compressing plunger away from the sample. (No adhesiveness is seen in graphs above.) Maximum negative force generated during probe return. The product of hardness and cohesiveness.

B1 - B2 DS P1 x _____ x __ A 1 - A 2 DT A2 __ A1

Resilience (PELEG, 1976)

( )

Adhesiveness

Adhesive Force (Fiszman and Damaio, 2000) Gumminess Applies to semi-solid products only if they have no springiness & undergo permanent deformation Cohesiveness A measurement of how well the structure of a product withstands compression Chewiness Solid foods only
56

The work necessary to overcome the attractive forces between the surface of the food and the surface of other materials with which the food comes into contact (e.g. tongue, teeth, palate). Work required to pull food away from a surface. The maximum force required to separate teeth after biting sample. Energy required to disintegrate a SEMI-SOLID food product to a state ready for swallowing. Related to foods with low hardness levels. The strength of internal bonds making up the body of the product (greater the value the greater the cohesiveness) The energy required to chew a SOLID food to the point required for swallowing it.

B1 P1 x __ A1 B1 __ A1 B1 P1 x __ x DS A1

The ratio of the work during compression (downward stroke only) of the second cycle B1 divided by that of the first cycle A1. The product of hardness, cohesiveness and springiness.

Why Choose Brookfield?
Brookfield Engineering is recognized around the world as offering high quality measurement instruments at an affordable price. Unsurpassed customer support is but one more reason to choose a Brookfield product when you are considering a viscometer, rheometer, texture analyzer or a powder flow tester. To find out about the in-depth service that we provide, ask any customer who has uses one of our viscometers. The CT3 offers the highest performance/cost ratio on the market. Distance accuracy is assured during calibration for each and every CT3 by storing the unique compensation curve for load cell deflection. Each load cell deflects naturally and uniquely as the force builds to the maximum range for the load cell. This unique deflection of each load cell is stored during calibration and applied to the drive system in real time as the test runs. This compensation assures accurate distance travel regardless of the load force recorded. The CT3 Texture Analyzer utilizes uni-axial compression and tension forces in combination with a selection from our extensive list of probes, grips and fixtures to test a wide variety of food, personal care products and industrial materials. Most tests desire to imitate conditions imposed on these products during manufacture, handling, and consumption or use. Characterizing the physical properties of your products in such an analytical manner provides "real life" insight and can be invaluable toward maintaining consistent, high quality manufacturing while minimizing cost. The Brookfield Texture Department can also provide customers with complete texture assessment service. We specialize in the development of novel and innovative test applications and accessories for solid and semi-solid materials, enabling our customers to maximize the practical value of their texture studies within all test environments.

Why Measure Texture?
Consumer products succeed in the marketplace in part because their "textural characteristics" are pleasing to customers. This is certainly true with food products but it also applies to cosmetics, pharmaceuticals, packaging, industrial materials and even adhesive type materials.

BROOKFIELD _ POWDER FLOW TESTER

What is powder analysis?
What are the industrial issues with powders?
The classic problem with powders is their failure to discharge reliably from bins, hoppers, silos, etc., and poor or unpredictable flow in feeders, dosing machines, packing machines, etc. This causes unwanted interruptions in the production process, leading at times to complete plant shutdown in order to correct the flow restrictions and stoppages. It also leads to variations in pack weight, mixture, performance and sensory properties of powder products. Quality Control Departments are constantly dealing with raw materials in powder form, which come from multiple suppliers. The variability in particle size and distribution, moisture content, and basic ingredients requires a battery of incoming inspection tests, none of which assure that proper flow will take place when loaded into the plant equipment. The Brookfield Powder Flow Tester is a single-solution instrument which can resolve this uncertainty. R&D Departments are constantly adjusting formulations of powder products to satisfy customer demand for improved properties: better coating action for paints, enhanced taste for spices, rapid dissolving of chemicals when put into solution. New formulations do not necessarily have the same flow properties, thereby leading to production problems when the process is scaled up to high volume. The Brookfield Powder Flow Tester can predict those problems so they can be prevented.

Particulate materials constitute a large group of solids that can range in size from sub micron particles to large rocks and minerals. Brookfield's Powder Flow Tester measures the flow behavior of bulk solid materials that have a top particle size of 2mm. At least 90% of the sample should consist of particles less than 1mm in diameter. In many instances, powders with larger particles can still be characterized effectively by sieving the material at 1mm and testing the fines (the fines control the flow properties of a material with a wide size range). The generic term used by Brookfield to name these materials is "powder", therefore the name of our instrument is "Powder Flow Tester". Unlike liquids which, under the influence of gravity, tend to have a horizontal surface, powders exhibit a structure, due to internal friction and cohesion, which allows them to form piles with angles relative to the surface on which they are placed. At ambient conditions, powders do not change flow behavior when subjected to variable shear rates, whereas most liquids do. However, pressure controls the strength of a powder (i.e., increases the resistance to flow) whereas a liquid will show limited change in rheology under pressure. In other words, the consequence of subjecting a powder to a compressive force is that the powder will flow less easily; the relationship between the compressive stress applied to consolidate the powder and the strength it obtains is the measurement of the powder flowability, or its "Flow Function". There is a need throughout industry to characterize powder flow properties and flow behavior. The Brookfield Model PFT Powder Flow Tester is a precision instrument of robust design that satisfies this need and more.

How can flow problems with powders be eliminated?
There is a proven scientific method, called the "Flow Function test", which can analyze powders for flow behavior. ASTM D6128 describes this procedure for compressing and shearing powder samples in a defined annular shear cell, using a well-defined methodology established years ago. Test algorithm for powder flow analysis requires compression of the sample contained in an annular cell to a defined axial load followed by torsional shearing. Raw data output shows torsional load values in red. Compression of sample is shown as axial load values in green.

The resulting data produces a "Flow Function", much like what is obtained for liquids when testing with a viscometer to create a "flow curve". Flow Function for powder sample shows "non-flowing" to "very cohesive" behavior at low consolidation stresses and "cohesive" behavior at higher consolidation stresses. Analysis of the "Flow Function" leads to calculation of the critical outlet dimensions of feeders, hoppers, etc., through which the powder will flow. Comparing the "Flow Function", or these critical dimensions, allows powders to be benchmarked, ranked and compared against one another for flowability. The dimensions can also be used to determine whether a particular powder will flow through an existing plant or process, or to determine what the geometry should be if purchasing new solids handling equipment.

Testing Service
for powder applications
To assist you in the evaluation of your powder for flow behavior, Brookfield offers a testing service prior to purchase. Provide Brookfield with samples of your product to obtain a complete test report. Data is presented in both graphical and tabular format for easy analysis and interpretation. The following example shows the report format and type of information that is presented. In the concluding section, calculations for critical arching dimension, rathole diameter and hopper half angle assess the potential for stoppages due to the powder flow behavior or equipment limitations.

Customer Test Report
DATA COLLECTED BY: BROOKFIELD POWDER FLOW TESTER

STANDARD TESTS This report follows four samples sent to our lab for evaluation. The specific graph for each sample is color coded for easy identification. Up to eight data sets can be shown on the same graph.

Bulk Density Graph (230cc Trough) This bulk density graph illustrates the density of the samples over different consolidating stresses. Samples #1 and #4 have almost identical loose fill densities of 900 kg/m³. At 9 kPa of consolidating stress, the density of Sample #1 rises to 1150 kg/m³ and Sample #4 rises to 1200 kg/m³. Samples #2 and #3 have similar loose fill densities ranging from 450-500 kg/m³. At 9 kPa of consolidating stress, the density of Sample #2 rises to 770 kg/ m³ and Sample #3 rises to 590 kg/m³ at 12 kPa of consolidating stress. In general a free flowing powder shows a relatively small change in density with more consolidating stress, while a cohesive powder shows a large change in density.

Flow Function Graph (230cc Trough) This flow function graph illustrates the flowability of the samples over different consolidating stresses. The x-axis parameter is the consolidating stress used to compress the sample; the y-axis parameter is the strength of the powder. Sample (Data Set) #2 is the most cohesive material of all, falling into the very cohesive range throughout all consolidating stresses. Sample (Data Set) #3 powder also falls into this category. Sample (Data Set) #4 is very cohesive at low consolidating stresses (below 1.5 kPa), cohesive at medium stresses (1.5 - 4.5 kPa), and easy flowing at high consolidating stresses (above 4.5 kPa). Sample (Data Set) #1 material is cohesive at consolidating stresses from 0 ­ 4.0 kPa, and easy flowing at consolidating stresses above 4 kPa. Sample 2 clearly exhibits the greatest difficulty for reliable flow behavior.

Wall Friction Angle Graph (230cc Trough) This graph illustrates the angles of wall friction for each powder over different consolidating stresses. At low normal stress (0.5 kPa) all materials had extremely high wall friction angles ranging from 40º to 65º. At a higher normal stress (4.75 kPa), the wall friction angles dropped to a range of 20º to 35º. Wall friction angles above 30º are considered very high and below 10º are very minimal. This indicates that Sample #2, and perhaps Sample #1, will have difficulty with reliable flow on the hopper wall surface.

CRITICAL ARCHING DIMENSIONS SAMPLE (DATA SET) #1 SAMPLE (DATA SET) #2 SAMPLE (DATA SET) #3 SAMPLE (DATA SET) #4

21 mm (0.85 in) 480 mm (19 in) 80 mm (3.1 in) 100 mm (3.9 in)

Internal Friction Angle Graph (230cc Trough) This graph illustrates the angles of internal friction at different levels of normal stress. The angle of internal friction is a measure of the friction between the powder particles as they slide against each other. Sample #1 and Sample #4 have the lowest angles of internal friction and will therefore flow more readily than the other two powders. The angle of internal friction for Sample #2 and Sample #3 is approximately 50º which is relatively high and indicative of potential flow problems.

The critical arching dimension is a conservative calculation of the powder's potential in mass flow behavior to build a stable bridge over the hopper outlet, thereby restricting flow. The arching values above indicate that the hopper opening must be greater than 480 mm (18.9 in) to ensure reliable discharge of all powders. The critical arching dimension for Sample #2 is much greater than the other three powders due to its very cohesive and "sticky" nature, thereby having a much greater tendency to form a stable arch. This calculation also applies to the design of any conveyance device directly downstream of the hopper, such as the spacing between flutes on a screw feeder. The Powder Flow Tester can also be used to calculate the critical rathole dimension which relates to a behavioral problem that may occur under core flow conditions. This calculation requires user input on bin shape, cross section dimension(s), and hopper type (wedge, conical). When this information is provided, the Powder Flow Pro software is able to automatically calculate the rathole diameter, as well as the hopper half angle.

BROOKFIELD _ WHY MEASURE VISCOSITY IN-LINE

Why measure viscosity in-line?
Why Measure Viscosity In-Line?
Practical application of viscosity measurement data often leads to the need for in-process control of viscosity. The installation of viscosity control equipment on a process can provide a level of control achievable by no other means. Variations in viscosity are detected and corrected instantly before they can negatively affect product quality. Real time viscosity control can reduce downtime and material waste by ensuring that the process is operating within its specified viscosity parameters. In many cases, the savings from increased efficiency can pay back the cost of the viscometer in only a few months.

Why Choose Brookfield?
Brookfield builds its Process Control Viscometers to the same high standards of performance and value as its Laboratory Viscometers. Particular attention has been devoted to making these instruments rugged and easy to maintain for long service in demanding industrial environments.

Questions to Consider
1. What is the viscosity range of your material? 2. Is your material Newtonian, Dilatant, Non-Newtonian, Thixotropic or Plastic? 3. What is the minimum, maximum and average pressure requirement of your application? 4. What is the minimum, maximum and average temperature of your application? 5. What is the minimum, maximum and average flow rate of your application? 6. Where in production would you like the viscometer: in-line, on the top of the tank or on the side of the tank? 7. What electrical code requirements do you have: NEMA 1 (general purpose--indoor) NEMA 4 (watertight/dust tight for indoor/outdoor use) NEMA 7 (explosion proof--Class 1, Div. 1&2, Group D) ATEX (explosion proof--Code: EE x d 11B T6) The above parameters may eliminate some of the instrument models because, for example, the viscosity is higher than the range of the instrument or outside of the pressure rating of the instrument. In many cases, more than one instrument may be applicable. Please allow us to assist you in choosing the best viscosity control system for your application.

In-Line Viscometers Provide Automatic Control of Process Fluid Viscosity
There are many ways that viscosity can be measured, such as capillary, vibration and rotational. These methods have different benefits and may work well for process monitoring or control but will likely not give the same values as laboratory or analytical methods. In general, laboratories require a more scientifically accurate measurement, while process control requires a stable, repeatable signal. Process measurements are made both in-line and off-line. A bench-top viscometer has often been used for off-line measurements wherein a sample of the process fluid is drawn and tested under controlled conditions (temperature, shear history, shear rate, etc.). In-line viscometers are immersed in the process stream. They measure and control continuously under process conditions helping to maintain a consistent quality product. The demands of these two environments are different, and it is unlikely the same equipment can be used for both or that the exact same results will be generated. However, if done properly, the results will follow the same trend and can be correlated to the bench top, making in-line measurement useful for ensuring consistent production quality.

In-line measurements give real-time, continuous readings of the fluid's viscosity during processing and consequently provide a means to automate the modification and viscosity control of the process fluid. While it is difficult to control all the factors present in the process that affect the fluids' viscosity (such as temperature, air bubbles, shear history, turbulence, pressure variations, etc.), if these factors are kept relatively constant, then good control can be achieved.
WHAT EFFICIENCIES ARE GAINED BY MEASURING IN-LINE?

TIME



For more information, call or visit our website to request your copy of our Process Viscometers Catalog

Automatic control of the process fluid viscosity insures consistent product all the time and reduces or eliminates human errors and expensive sample testing. Also, it provides for a complete record of how the process varied over a span of time, instead of at just one point in time.
WHAT ARE THE TOP THREE FACTORS TO CONSIDER WITH CHANGING YOUR MEASUREMENT PROCESS?

For process measurements, the critical factors are stability, repeatability, and sensitivity to changes in viscosity. In the laboratory or for analysis environment controls (e.g. temperature, flow, sedimentation, air, etc.) and scientific measurements (controlled shear, geometry measurements and sample preparation) must also be included.
HOW DOES MONITORING THE VISCOSITY AFFECT PRODUCT QUALITY?

Most products are formulated to flow or spread in a controlled manner. Monitoring viscosity at critical shear points ensures that the product will act the same way every time the customer uses it. This is the most tangible indicator of quality.

I've read page 7 regarding model selection, and I've reviewed the models available to me, but I'm still unsure -- can you test my product for me? Brookfield has a test and recommend service wherein we will test your sample and make a product and method recommendation to help get you up and running. Please call us for details. Do I need an accessory? There are no firm rules for determining when an accessory is required. If your test method is not already established within your company, we recommend calling Brookfield so that we may review the best choices available for your specific application. As a general guideline, you may want to consider and discuss with us the accessories shown in blue if any of the following apply to your situation: - The product is similar to the consistency of water. Consider: UL Adapter - The product is similar to the consistency of peanut butter. Consider: Helipath Stand - The product has suspended solids, similar to relish. Consider: vane spindles - The product sample is limited. Consider: Small Sample Adapter accessory or Cone/Plate Viscometer - The product must remain at a consistent temperature. Consider: TC series water bath - The product is wax-like and needs to be melted at a high temperature just like asphalt Consider: Thermosel - The product is very paste-like similar to solder paste. Consider: Spiral Adapter or R/S Rheometer Do I need software? Our software provides an easy way to gather data, plot graphs, export data to Excel and should be considered if detailed records are needed or if you want a more automated process. Software is also ideal for multiple operators and complex or repetitive testing. Do I need a viscosity standard and when should it be replaced? Yes, verification of instrument calibration with a viscosity standard should be done periodically to ensure that your instrument is in calibration and providing reliable results. We typically recommend replacement of standards every 6-12 months depending on the frequency of use and material tested. Is verifying calibration the same as the yearly calibration service that Brookfield recommends? No, verifying calibration is performed by you using viscosity standard fluids in accordance to the procedure outlined in the instrument's operator manual. Our Calibration & Certification Service is similar to getting your car's oil changed and a tune-up. You return your instrument to us, and we clean, adjust and lubricate the internal mechanism. We also replace part of the sensing system when necessary, and certify that the instrument is working properly in compliance with ISO 9000 regulations.

BROOKFIELD _ GLOSSARY

3A A US industrial standard for process equipment design; required certification for clean-in-place capability. Absolute Viscosity The viscosity value associated with a Newtonian material Angle of Wall Friction Represents the friction between the sliding powder and the wall of the hopper or chute at the onset of flow Arching Dimension Minimum hopper outlet size needed to insure that the powder will discharge in Mass Flow instead of forming a stable arch across the opening. ASTM American Society of Testing and Materials Autorange Maximum viscosity value that can be measured using a specific spindle at a designed rpm. Bob spindle used with PVS and R/S series rheometers; also referred to as "bob/stator" because it does not rotate on this instrument. The sample cup rotates instead, causing the shearing action. Bulk Density The mass of the powder divided by its total volume Cohesion A measure of the strength retained by a powder after it has been compacted to a given consolidation level Concentric Cylinder A cylinder within a cylinder. For viscosity measurement, a cylindrical spindle rotates within a cylindrical chamber. Also known as "Coaxial Cylinder" because both cylinders have the same center line. Consolidation The process of applying a normal and a shear stress to a bulk solid to move the particles together in order to observe any increases in its cohesion, bulk density, etc. Core-Flow A first in-last out discharge pattern where the powder flows from the top of the vessel through a vertical channel above the outlet. Powder that is near the walls of the vessel remain stagnant until the level descends to the point where the powder is at the top surface. dyne·cm A unit of measurement for torque. Gap The distance between the spindle and the chamber or cup in which the spindle is rotating.

Hopper Half Angle Maximum angle of the converging hopper wall (from the vertical axis) to insure mass flow. Angles greater (shallower) than this will produce core flow. In-line Process viscometer placement in a pipe. Loose Fill Density The bulk density of the powder in the trough before any stress is applied. Mass Flow A first in-first out discharge pattern where the powder flows at the vessel walls and all the material is in motion. NIST National Institute of Standards and Technology. US Government organization for test standards. Newtonian a material whose viscosity value is the same at all shear rates (e.g. water, honey). Non-Newtonian A material whose viscosity changes as shear rate changes (shampoo, mayonnaise). On-line Use of a process viscometer to provide continuous viscosity measurement of a material. Pneumatic Air operated PP Plate and plate geometry. Rathole Diameter Minimum outlet diameter of a core flow hopper needed to insure that the powder will flow instead of forming a stable rathole. Relative Viscosity The viscosity value of a non-Newtonian material at a defined shear rate. RPM Rotations per minute; a unit of measurement for spindle speed. RTD Resistance thermal detector; type of sensor for measuring temperature sec-1 The scientific unit of measurement for shear rate; expressed as "reciprocal seconds" or "inverse seconds." Shear Rate The velocity gradient in a flowing material; the shape and rotational speed of the spindle rotating in a chamber or cup are used to calculate shear rate.

Shear Stress The force per unit area used to move a material. Spindle Geometry The shape of a spindle. Brookfield spindles supplied with standard Viscometers/Rheometers (Dial Reading, DV-E, DV-I Prime, DV-II+Pro, DV-III+) are disc type. Other choices include Cylindrical, Cone, Plate, KREBS, etc. Torque Range The torque measurement capability of a Brookfield Viscometer/Rheometer measured in dyne·cm; designations such as LV, RV, HA or HB are used to define the Torque Range for a specific instrument. Torque % The amount of torque resistance measured by a rotating spindle immersed in a material. Yield Stress The amount of force required to cause a material to flow.
