  • Bulk Density of Powders Made Easy
    . The greater the change in a material's bulk density from initial fill to final consolidated bulk density, the less likely that the material will flow. But, back to the easy method of realizing bulk density. Recently, Brookfield Engineering developed a Powder Flow Tester. This instrument is used
  • Pharmaceutical Powders Small Sample Sizes Yield Big Results
    of pharmaceutical powders. With the induction of small volume shear cell accessory to its popular Powder Flow Tester, powder sample volumes needed for testing have been reduced from 263cc to a mere 43cc. This small shear cell was specifically designed to address the pharmaceutical industry with no sacrifice
  • Can You Measure Powder Flowability? (.pdf)
    , increase the internal friction) of a powder, whereas a liquid will show limited change in rheology under pressure. The consequence is that the powder gains strength and flows less easily. What are the industrial issues with powders for food processors?. The classic problem is their failure to discharge
  • Pressure Distribution of Stored Bulk Solid Materials
    this type behaviour is the Brookfield Powder Flow Tester (See Figure 1). Using shear cell technology, this device shears a small sample of the powder to measure the frictional forces acting between the powder particles. !
  • Can You Predict Powder Flow Behavior By Measuring Density
    Function (see Figure 3) and a Density Curve (see Figure 4). Powder flow testers, which use shear cell methodology, have been around for a long time. Recent breakthroughs in the design of these instruments have made them much more affordable. In addition, they are now very easy to use, run tests
  • Processing Milk Powder - The Flowability Challenge
    powder. Note in the flow function graph that some of the powders are "easy flowing" while others are "cohesive". The graph plots the strength of the powder (the force needed to cause the powder particles to slide against each other) against the consolidation stress (gravity's effect on the powder
  • A Cure for Hammer Rash: Measuring Powder Flowability with Shear Cell Testing
    Preventing discharge problems in vessels and containers requires a detailed understanding of your powder's flow characteristics. This article explains how a shear cell tester can simplify and speed tests for measuring a powder's flow behavior. With built- in software to quickly analyze the test
  • A Guide to Measuring Paint Viscosity vs Temperature
    in Electrical Engineering. Previously, he had been employed at Measurement Computing Corp. in Norton, MA since 1992 in Sales, Marketing and Technical Support. In his current capacity at Brookfield, he manages all educational seminars and trainings and is lead specialist in Brookfield's new Powder Flow
