HGM series Micro Powder Grinding Mill absorbed the European advanced technology and many engineers’ ripe experience, combining with the actual requirement and proposal of our customers’, have been developed on the basis of our professional engineers’ hard researching. It is mainly applied to grind non-inflammable, non-explosive and brittle materials with Mohs hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin, gypsum, etc, totally more than 100 kinds of materials. Product fineness can be controlled between 0.047mm (47 micron) and 0.005mm (5 micron).
Compared with jet mill, agitation mill and ball mill, if the fineness and motor power is the same, its product capacity is twice than others.
2. Longer lifetime of spare partsThe roller and ring are made of special material, which improve the grinding efficiency a lot. For same material and final size, the lifetime of its wearing parts can reach to more than one year, about 2-5 times as long as that of vertical shaft impact crusher and turbo-mill. Especially when handling calcium carbonate and calcite, the lifetime can reach 2-5 years.
3. High safety and reliabilityThere are no rolling bearings and bolts in grinding chamber, so problems caused by bolts shedding or wear of bearings and seal components will never happen.
4. High fineness of productsThe product fineness can reach D97≤5 micron.
5. Pro-environmentThe application of pulse bag filter and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard.
The whole set HGM Micro Powder Grinding Mill consists of (see sketch 1) hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone, pulse bag filter system, high pressure positive blower, air compressor and electrical control systems.
