    Calcite mineral mill, heavy calcium mineral mill

    Calcite mineral mill, heavy calcium mineral mill

    Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate.
    Calcite is the primary mineral in metamorphic marble. It also occurs as a vein mineral in deposits from hot springs, and it occurs in caverns as stalactites and stalagmites.
    Calcite powder is heavy mass calcium carbonate, also be called “heavy calcium” for short. Calcite powder usually used as filler, widely for artificial floor tiles, packing, and rubber, and plastic, and paper, and paint, and paint, and ink, and cable, and building supplies, and food, and medicine, and textile, and feed, and toothpaste such as daily chemical industry, for fill agent up to increase products volume, reduce production cost.
    Calcite mineral mill:
    1) High capacity
    2) Low consumption
    3) Finished fineness adjustable
    Detailed Product Description about Calcite mineral mill
    Calcite mineral mill 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, and talc etc, totally more than 100 kinds of materials. Product fineness can be controlled between 300~3000 mesh (47~5 micron) 
    Comparable with ball mill, Calcite mineral mill has features of low cost, high capacity, easy operation; Comparable with Raymond mill for coarse powder up to 325 meshes, it can produce fine powders between 47 and 5 microns (300 to 3000 meshes)
    Performance and features of Calcite mineral mill
    1. High efficiency
    Under the same final size and power, the product capacity of micro powder mineral mill is twice than jet mill and agitation mill.
    2. Long lifetime of wearing 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 DMC-120 pulse dust collector and muffler reduce the pollution and noise of the dust, which has reached national environment protection standard
    Production Line Configuration of Calcite mineral mill
    The whole set HGM Calcite mineral mill 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 Calcite mineral 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.
