Calspar Grinding Mill (HGM Series)

Calspar Micro Powder Mill is able to produce micropowder between 47 and 5 microns(400~3000 mesh) Calcite Micro powder grinding mill It is mainly applied to non-inflammable, non-explosive and brittle materials with Mohs hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin, gypsum, talc etc, totally more than 100 kinds of materials. The fineness of Calspar can be controlled between 400~3000 mesh (47~5 micron) Performance and features 1. High efficiency Under the same final size and power, the product capacity of micro powder grinding mill is twice than jet mill and agitation mill. 2. Quick-wear parts with longer life 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 3-5 years. 3. Security 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≤ 5μ M. 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 The whole set Calspar Grinding 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 Electrical control systems. Working Principle With the help of reducer, the electromotor will drive the main bearing and each dial. At the same time, plunger will help dial drive the rollers which are rolling in the ring. Hammer crusher will crush the big materials into small ones, then the elevator will send them to the hopper. After that, the electromagnetic vibrating feeder and feeding pipe will send the materials to the middle of first dial evenly. 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 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.
