Marble Grinding Mill is a new type machine to grind Talc Stone into super thin Powder. The final Powder size can be from 5micron to 47micron as per 97% passing rate. Marble grinding mill is mainly applied to non-inflammable, non-explosive and brittle materials with Mohs hardness scale under seven, such as calcite, chalk, limestone, dolomite, carbon black, bentonite, kaolin, talc, mica, magnesite, illite, pyrophyllite , roseite, sea-foam, attapulgite , rectorite, diatomite, barite, gypsum, alunite, graphite, fluorite, rock phosphate, kalium ore, pumice etc. totally more than 100 kinds of materials. Finished powder products are in the 325meshs -3000meshs, and yield can be up to 0.5-12 tons per hour. There are five types of Shanghai CLIRIK HGM series marble grinding mill, they are HGM80, HGM90, HGM100, HGM100A and HGM125. Performance and features of Marble grinding mill, stone grinding mill 1. High efficiency 2. Long lifetime of wearing parts 3. High safety and reliability 4. High fineness of products 5. Environment friendly Working Principle of Marble grinding mill, stone grinding mill 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 powder 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.
