Powder flow behavior analyzer Powder rheometer ASTM D6128 ASTMD6682\
1. Application instructions
1. Describe the flow behavior by analyzing the dynamic data of powder shear. Arch/rat hole structures often appear in the powder industry in processing, storage, transportation and silos.
2. Friction between materials and between materials and solid walls.
3. In the design of the hopper, the size of the discharge opening, the inclination angle of the hopper wall and the pressure of the powder on the hopper wall. Unreasonable design of the hopper will cause great difficulties in production.
4. These behavioral characteristics that affect powder fluidity can be quantitatively analyzed by measuring the internal strength, flow function, friction function, density, time function and other data of the powder to quantitatively analyze the above phenomena and states.

4. How it works
The automatically controlled load is applied to the shear cover and acts on the sample in the annular shear box rotating at a known speed, thereby realizing the flow of the sample and the sample under different pressures.
