  • 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
  • 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. !. Microsoft Word - Pressure Distribution of Bulk Solid Materials.doc
  • 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
  • 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
  • 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
  • Induced Anistropic Behavior in a Schulze Direct Shear Tester (.pdf)
    for decades. Initially this value. was measured using a tester developed by Jenike [1]. The initial shear cell provides a means of. measuring the yield locus of powder material, but is difficult to use and requires trained. technicians to achieve reasonable data. One of the limitations is the small
  • A Guide to Measuring Paint Viscosity vs Temperature

The choice of rota-. check this when ramping speeds, look for this hysteresis. If. training and is lead specialist in. Brookfield’s Powder Flow Tester. tional speed must provide
  • 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
