HGM Series Three-ring Medium-speed Micropowder Grinder
On basis of more than 20 times experiments and improvement, introducing the latest mechanical techniques of Sweden, HGM Series Micropowder Grinder is Superfine Grinding Mill, it is the latest industrial superfine powder processing machinery.

HGM Series Three-rings and Medium-speed Micro-powder Grinder can grind calcite, limestone, calcite, dolomite, kaolin, bentonite, talc, ilite,pyrophilite, barite, meerschaum, fluorite, potash ore and other more than 200 kinds of materials that Mohs hardness is below 7, non-explosive,non-flammable minerals.

The mainframe through reducer makes the main shaft and all the turntables rotating which 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 crusher and the later is transmitted into the hopper by elevator, then the vibrating feeder sends the materials onto the middle of the upper turntable in a stable and well-proportioned way, which are separated under the centrifugal force and fall into the raceway where they are crushed, grinded, rolled. Through the first process, enter into the second turntable then the third one. Hyper centrifuger indrafts the air inside and carries the larger powder into the collecting powder machine. The vortex made by rotating turbine of the collecting powder machine lets the larger ones recycled back into the grinding chamber for regrinding, then smaller ones enter into the cyclone collector and final products are discharged by the valve, airflow with little fine dust is refined by pulse dust catcher and 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 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%.
