Background

The automatic micro powder shaping machine can grind the materials to the ultra-fine granularity above 3000 meshes through fine processing of the materials, and is common equipment for processing micro powder in the market. The motor of the automatic micro powder shaping machine drives the main shaft and each layer of rotary table to rotate through the belt pulley, the rotary table drives dozens of ring rollers to roll and rotate in the grinding ring roller path through pins, large massive materials are crushed into small particles through the crusher and then are sent into the storage bin through the lifter, the electromagnetic vibration feeder evenly sends the materials to the middle part of the upper rotary table, the materials scatter to the circumference under the action of centrifugal force and fall into the roller path of the grinding ring to be stamped, rolled and ground by the ring rollers for crushing, the materials fall into the second layer and the third layer after being crushed through the first layer, the external air is sucked into the crusher through the suction effect of the high-pressure centrifugal fan, and coarse powder crushed by the third layer is brought into the powder selecting machine. The vortex generated by the worm wheel rotating in the powder selecting machine makes coarse particle materials fall back for regrinding, fine powder enters the cyclone powder collector along with the air flow and is discharged by a discharge valve at the lower part of the cyclone powder collector to obtain a finished product, and the air flow with a small amount of fine dust is purified by the pulse dust collector and is discharged by a fan and a silencer.

The gap between the grinding ring and the grinding roller is smaller, so that the materials can be ground and shaped only when entering the gap, large-particle materials cannot enter the gap, and can only enter the grinding gap after being crashed by collision with other materials, and the grinding efficiency of the large-particle materials is low. Or the specification of the material particles entering the micro powder automatic shaper needs to be strictly controlled. Thereby leading to a narrow application range of the micro powder automatic shaper.
