HGM Three-Rings & Medium-Speed MicroPowder Mill

Brief instruction of Three-rings and Medium-speed Micropowder Grinder:
HGM series three-ring medium speed micro-powder mill is a new type of mill for making super fine powder. It is the latest type of products in the world that adopts Swedish techniques to meet the requirements of grinding industry and market in our country. It is specially designed for customers of super fine powder.

Working principles of three-ring medium speed micro-powder mill:
The main motor drives main shaft and every turnplate through reducer. The reducer drives dozens of rollers to rotate against race way of ring through pin. Small pieces crushed by crusher are transported into hopper by elevator, and then vibrating feeder will feed materials to central part of upper turnplate evenly.
The materials are scattered around under centrifugal force and fall down to raceway of ring to be crushed into powder. After ground in the first race way, the materials go to the second and third turnplate.
The high pressure centrifugal blower sucks external air into the mill and carries the powder after third turnplate into classifier. Turbine in the classifier makes the coarse powder drop down for regrinding.
The finer powder shall go into cyclone powder collector together with air current and go down through discharge valve as final product; at the same time, air current with a little dust goes out through blower and noise reducer after purified by impulsed deduster.
