HGM series ultra-fine powder mill consists of a main mill, powder classifier, powder collector, dust collector, fan, muffler, soundproof room, crusher, hoist, silo, feeder, and other parts.

After the large material is broken into small particles by the crusher, it is sent to the hopper by elevator, and then the material is evenly sent to the bulk material plate on the upper part of the turntable through the feeder and the inclined material guide pipe. When the mill is working, the grinding roller rotates and rolls in the ring. The material is scattered to the periphery under the centrifugal action and falls into the grinding chamber, where it is stamped, rolled, and ground by the grinding rollers in the ring.

As the high-pressure fan continuously sucks the air inside the equipment, the materials after multi-layer crushing are brought into the powder classifier, and the high-speed rotating impeller screens them, the unqualified materials fall back and regrind, and the qualified materials are then The airflow enters the cyclone powder collector. The dust particles with higher density fall and are discharged from the discharge valve at the bottom to become the finished product. The fine dust with lower density enters the dust collector with the airflow and adheres to the surface of the filter bag. The pulse valve controls the high-pressure airflow from the inside of the filter bag instantly The dust adhering to it will fall down due to the vibration of the filter bag, and the conveyor at the bottom will send the materials collected in the two places out for finished product packaging.
