HGM series of three-rings and medium-speed micro powder grinder is a new type of making micro powder machines through more than twenties times research and improvement, depending on two decades of hard work & experience and inputting the latest mechanical techniques of Sweden. It is an incorporated one of the two countries and a leader of the grinding industry nowadays.

1. HGM Series of Three-rings and Medium-speed Micro-powder Grinder is widely used in making
fine powder or ultra-fine powder, and the raw materials should be non-inflammable and non-
explosive under the Moh's hardness less than 6 grade such as limestone, calcite, dolomite,
kaolin, bentonite, talc, illite, pyrophillite, barite, meerschaum, fluorite, potash ore, etc. The
lifetime of spare parts is relied on the hardness of raw materials, and is lowered once the Moh's
hardness is up to 4-6 grades.
Features of of HGM series Three-rings and Medium-speed Micro-powder Grinder:
Applications: 325-2500mesh fine powder grinding
Field of application: Agriculture, biology, construction materials, glass / ceramics, mining,
mineralogy, metallurgy
Feed material: medium-hard, hard, brittle, tough
Size reduction principle: pressure
Material of grinding Ring and Rollers: manganese steel, Chromium - molybdenum Alloy
Dust Filter System: With Bag Dust Filter
Durability: depending on feed material
Working Principle of HGM series Three-rings and Medium-Speed Micro-powder
Grinder:
The material in the Silo will fall down into the Feeding tube evenly through the Vibrating Feeder,
and then fall onto the upper scattering plate, after that will scatter on the gap between the
roller and ring. The material into the inner wall of the rollers will be reground, and then fall
down onto the lower scattering plate. And the fine powder conforms to the standard will be
discharged into the Dispersive Twin-pipe Cyclone Separator, and then be discharged. And the
massiveness will enter the grinding wall to be reground. The air current with the dust will enter
into the lower part of the Pulse Bag Dust Catcher, and then be discharged through the
Rotational Discharging Device after filtering dust.
