Crossing shearing force collides the inner wall of powder particle and pulverizing chamber, so that powder particle be made to be crushed, sinks to of bottom
Grain can be rotated upwards by throwing disc, to promote contact of the high pressure gas with particle, smashed powder enter screen-dividing machine into
Row screening, particle is biggish to be entered feed hopper by air conveying device and is crushed again, so that the product grading made is uniform,
Pulverizing chamber is cleaned by spray head, it is convenient and simple, and the dust occurred when cleaning is reduced, after the water after cleaning is by filtering
Particle can still be recycled, it is practical.
