HGM Series Micro Powder Mill

HGM Series Three-rings Micro-powder Grinder Mill is also called superfine grinding mill, it’s a new type superfine powder process grinder designed by Vipeak and based on many years’ grinding mill production experience, this new type grinding mill absorbed advanced machinery manufacturing technology from Sweden and it was made after 20 times tests. HGM series grinding mill is absolute advanced leading machine in grinding mill industry. In addition, this mill 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.

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 airstream with the dust will enter into the lower part of the pulse bag dust catcher, and then being discharged through the rotational discharging device after filtering dust.

Advantage 1
Service life is longer than wear-out part’s of impact crusher and turbine crusher if material and product size are same.
Advantage 2
Under the condition of same material, power and final product size, its capacity is higher than jet mill and stirred mill by 40%.
Advantage 3
Final size of the material processed by superfine mill could reach d97≤5μm.
Advantage 4
No antifriction bearing and bolt inside the grinding cavity, no bearing or sealing element or bolt falling out and damaging machinery situation.
