HGM MicroPowder Mill

HGM micro powder mill (Full name is HGM series three-ring & medium-speed micro-powder mill) is the grinding equipment used to process fine powder and super-fine powder.HGM series of three-rings and medium-speed micro powder mill 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.

HGM MicroPowder Mill Applying Area

HGM micro powder mill is widely used in making fine powder or micro 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 grade.

HGM MicroPowder Mill Working Principle

The motor drives the main shaft and every turnplate through the reducer. The reducer drives dozens of rollers to rotate against race way of ring through pin. Small materials crushed by hammer crusher is transported into hopper by elevator, and then vibrating feeder shall feed material to the central part of upper turnplate evenly. The material falls to circle under the centrifugal force and comes down to raceway of ring to be crushed into powder. After grinded in the first race way, the material goes to the second and third turnplate. The blower inhales the external air into the mill and carries the powder after third turnplate into powder-separator. Turbine in the separator makes the coarse powder drop down and regrinded and the fine 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 dusts goes out through blower and muffler after purified by filter.

HGM MicroPowder Mill Features:

1. High efficiency and lower consumption. In the condition of the same material, power and the fineness, its capacity is increased by 40% compared to the jet mill and the mixing grinder.

2. Longevity. In the condition of the same power and the fineness, the spare parts have a longer lifetime, usually more than one year, to the shaft impactor crusher and the turbine crusher.

3. Non-Bearings and non-bolt in the grinding chamber. Because of this, these questions destroying the machines can never exist for bearing, sealing element or the bolts loose.

4.The fineness of final products can add up to 5μm, and screening rate is 97%。
