Methods The characteristics of powder flow behavior were analyzed, and the data model was adopted to pass the automatic control system.

PC

The combination of software, real-time dynamic data acquisition and analysis of the curve through the yield shear function of powder shearing, consolidation, time stress and strain relationship,

Pre-compressed until steady state flow

.

Third, the scope of application: chemical, ceramic processing, food, cosmetics, pigments

Solve the problem

: If the compression arch is subjected to the pressure of the silo, the consolidation strength will increase, resulting in arching; the arched arch materials will mesh with each other in the arch bridge; the adhesive adheres to the arch moisture, and the electrostatic adsorption causes the powder to adhere to the wall. Force-enhanced arching; air pressure-balanced arch: the unloading device is not well sealed, resulting in a large amount of air leaking from the bottom into the bin to balance the upper and lower air pressure; in the storage and conveying system of the powder and pellets, the fluidity of the material, Friction between materials and materials and solid walls; 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, the unreasonable design of the hopper will cause great difficulties in production. These behavioral characteristics that affect the fluidity of the powder cannot be solved by traditional measurement methods; the machine measures internal strength, flow function, internal friction function, density, time consolidation function, wall friction, bond index, and air. Quantitative analysis of the above phenomena and states by dynamic data such as temperature and humidity
