AI Technical Summary
Existing technologies are insufficient for efficiently pulverizing tough materials, especially plant fibers and elastic polymers, resulting in poor pulverization performance.
It adopts a grinding design with pressure plate and material collection trough, which replaces instantaneous impact with continuous static pressure crushing, and extends the material residence time through a throwing-gathering cycle design to ensure multiple crushing.
It improves the cell wall breaking effect of tough materials, is suitable for the pulverization needs of ultrafine drug raw materials, and can flexibly adjust the pulverizing force type according to the material properties to reduce the residual amount in the pulverizing cylinder.
