Granite powder milling medium speed mill

Granite is the most widely distributed plutonic intrusive rocks. The main mineral components are quartz, feldspar and biotite, lighter in color, gray and red meat is the most common, with granular and massive structure. Granite is both beautiful and compressive strength and high quality construction materials.
Granite powder milling medium speed mill which is designed by Clirik engineers and technicians on the basis of multiple innovation, test and experience over two decades, has absorbed many advantages of home and abroad mill manufacturing technique. It has been proved by thousands of customers that our machine has outstanding features and stable quality. Our granite powder grinding equipment can upgrade its production and the additional value which is suitable for our customer to use. It is the ideal equipment for fine milling.

There are five types of Shanghai CLIRIK HGM series granite powder milling medium speed mill, they are HGM80, HGM90, HGM100, HGM100A and HGM125. The finished production fineness can be reached 300meshes~3000meshes, 5-47 micron. The capacity (ton/hour) ranges from 0.4T/H to 12T/H.

>>Introduce of Granite powder milling medium speed mill:
Illite grinding mill finished product fineness: 300 mesh ~ 3000mesh.

>>Application of Granite powder milling medium speed mill:
Granite powder milling medium speed mill is mainly applied to non-inflammable, non-explosive and brittle materials with Mohs'  hardness 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.

>>Device of Granite powder milling medium speed mill:
Granite powder milling medium speed mill mainly consist of hammer crusher , micro powder main unit, Frequency conversion classifier, powder collector, pulse dust cleaner, high pressure positive blower, air compressor, muffler, electrical apparatus control system, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder.

>>Features of Granite powder milling medium speed mill:                          
1.   High efficiency
Under the same final size and power, the product capacity of ultrafine mill is twice than jet mill and agitation mill.
2.    Longer lifetime of spare parts
The 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 reliability:
There are no rolling bearings and bolts in grinding cavity, so problems caused by bolts shedding or wear of bearings and seal components will never happen.
4.    High fineness of products
The product fineness can reach D97≤5μm.
5.    Environment friendly
The application of pulse dust collector and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard.

>>Working principle of Granite powder milling medium speed 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 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.
