Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different
crystal forms of calcium carbonate. A few of limestone are composed from skeletal fragments of marine organisms such as coral or foraminifera.
Limestone is usually processed in fine or super fine powder by limestone mineral mill, mine mill. Limestone mineral mill, mine mill is a main kind of stone grinding mill. Limestone grinded by CLIRIK limestone mineral mill, mine mill has numerous uses: as a building material, as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints, and as a chemical feedstock.
1) The Application of limestone mineral mill, mine mill:
HGM125 limestone mineral mill, mine mill 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 325~2500 mesh.
2) Working Principle of limestone mineral mill, mine 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 materials 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.
3) Performance and features of limestone mineral mill, mine 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=<5um.
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.
