Application of HGM100A ultra fine grinding equipment: HGM100A ultra fine grinding equipment is mainly applied to 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 325~3000meshes. Production Line Configuration of HGM100A ultra fine grinding equipment: The whole set HGM100A ultra fine grinding equipment (calcite carbonate grinding equipment, chalk grinding equipment, limestone grinding equipment, dolomite grinding equipment, kaolin grinding equipment, bentonite grinding equipment , talc grinding equipment, mica grinding equipment, magnesite grinding equipment, pyrophyllite grinding equipment, ceyssatite grinding equipment, barite grinding equipment, gypsum grinding equipment, alunite grinding equipment, granite grinding equipment, fluorite grinding equipment, phosphate rock grinding equipment, kalium ore grinding equipment , float stone grinding equipment) consists of hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems. Working Principle of HGM100A ultra fine grinding equipment: The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings. The high pressure centrifugal blower will inhale air from outside and blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse material return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler. Performance and features of HGM100A ultra fine grinding equipment: 1. High efficiency 2. Longer lifetime of spare parts 3. High safety and reliability: 4. High fineness of products 5. Environment friendly
