Working principle

Bulk material by hammer crusher to the desired size, by lifting machine into the hopper, the feeding device is uniformly continuous feeding within the host, into the host material diversion tube with inclined to bulk disk on the upper part of the host turntable. The host work, dozens of grinding roller rotation, rolling in the loop. But the material under the action of centrifugal force was scattered to the surrounding bulk disk and fall into the grinding chamber, the ring road was grinding roller stamping, rolling, grinding.

Through the multilayer crushing milled material, the fan airflow into the powder selecting machine for powder classification, in the powder selecting machine impeller role, does not meet the requirements of the fineness of grinding cavity milling material falling back again, meet with airflow into the cyclone powder collector within the Department of separation of powder fineness required material collection, and from the bottom of the discharge device discharges is finished powder. The remaining portion of the powder from the cyclone upper powder feeder into the pulse dust collector, and adhere to the surface of the filter bag, pulse valve to control the high pressure air to make it instantly blowing bag filter bag to internal cause severe swelling fluctuation, powder through the filter bag suddenly jitter drop bombs adhesion, fall in the lower part of the dust remover of the powder. The screw conveyor will powder two collection collection of discharge is finished. Air filter silencer wind machine after discharged into the air. This system belongs to the open system, running under the condition of negative pressure.
