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.

HGM series of three-rings and medium-speed micro powder grinder 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.

Main 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 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 5μm, and screening rate is 97%.
