description :

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

HGM series of three-rings and medium-speed micro powder grinder is widely usedin making fine powder or micro powder, and the raw materials should be non-inflammableand non-explosive under the Moh's hardness less than 6 grade such aslimestone, calcite, dolomite, kaolin, bentonite, talc, illite, pyrophillite, barite,meerschaum, fluorite, potash ore, etc. The lifetime of spare parts is reliedon the hardness of raw materials, and is lowered once the Moh's hardness is upto 4-6 grade.


The mainframe through reducer makes the main shaft and all the turntables rotatingwhich lets the rollers and the ring rolling and rotating with dowel pin.First the large ones of the materials is crushed into small ones by the hammer crusherand the later is transmitted into the hopper by elevator, then the vibratingfeeder sends the materials onto the middle of the upper turntable in a stableand well-proportioned way, which are separated under the centrifugal force andfall into the raceway where they are crushed, grinded, rolled. Through the firstprocess, enter into the second turntable then the third one.Hyper centrifugerindrafts the air inside and carries the larger powder into the electing powder machine.The vortex made by rotating turbine of the electing powder machine letsthe larger ones recycled back into the grinding chamber for regrinding, then smallerones enter into the cyclone collector and final products are discharged bythe discharge valve, airflow with little fine dust is refined by pulse dust catcherand discharged through the blower and the muffler.
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 milland the mixing grinder.
2. Longevity. In the condition of the same power and the fineness, the spare partshave a longer lifetime, usually more than one year, to the shaft impactor crusherand the turbine crusher.
3. Non-Bearings and non-bolt in the grinding chamber. Because of this, these questionsdestroying the machines can never exist for bearing, sealing element or thebolts loose.
