The flow behior characterization was described by analyzing the powder shear dynamic data, The powder  arch/rat hole structure is common during the process of processing, storage, transportation, and SiloSuch as compression arch subjected to bin pressure consolidation strength increase lead to knot the arch, The clam shape arch material meshes with each other in the arch of the aperture form arch.The adhesion arch adhere to moisture and electrostatic adsorption cause the powder and the silo wall adhesion to enhance the arch.Air pressure balance arch: the discharge device is not well sealed, causing a large amount of air to leak from the bottom into the chamber and make the upper and lower aire pressue balance.In the storage and delivery system of the powdery and granular materials, the flow of material, Friction between material and material and solid wall;In the design of hopper, The size of the discharge opening, hopper wall slope Angle andThe pressure of the powder to the wall, unreasonable design of hopper  caused great difficulties in production;The behior characteristics that affect the liquidity of the powders cannot be solved by traditional measures.This machine by measuring the internal strength, flow function, internal friction function, density function, Time consolidation function, wall friction, caking index, dynamic data such as temperature and humidity in the air ,quantitative analysis the above phenomenon and state.
