Calcite ultrafine mill Brief description:

It is mainly suitable for ultrafine mill processing of non-flammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤6 such as calcite, chalk, limestone, dolomite, carbon black, kaolin, bentonite, talc, mica , Magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomaceous earth, barite, gypsum, alunite, graphite, fluorite, phosphate rock, Pumice and other more than 100 kinds of materials, fine-grained finished products in the 325-3000 mesh between the arbitrary regulation, the output of up to 0.4-4.5 tons per hour.

Calcite ultrafine mill equipment components:

A full set of configuration including hammer crusher, bucket elevator, storage silo, vibrating feeder, micro grinding machine, frequency classifier, double cyclone powder collector, pulse dust removal system, high pressure fan, air compressor, electrical control system.

Calcite ultrafine mill works:

Work, the host motor through the reducer drive spindle and turntable rotation, the edge of the turntable roll pin drive dozens of roller roll in the grinding ring raceway. The chunks of material are crushed into small particles by a hammer crusher and then sent to the storage bin by the elevator. After being vibrated by the feeder and the inclined feeding tube, the materials are uniformly sent to the bulk material pan on the upper part of the turntable. Under the action of centrifugal force, the material scatters to the periphery and falls into the raceway of the grinding ring, which is impacted by the ring roll, rolled, ground and processed into powder by the processing of the three-layer circular path. The high pressure blower suctions the outside air Inhaled machine, and the crushed material into the separator. Pulverizer rotating impeller coarse material back down and regaining, meet the requirements of the fine powder is with the air into the cyclone powder collection device by the lower part of the discharge valve is the finished product, and with a small amount of fine dust flow is passed Pulsed dust purifier discharge through the fan and muffler.

Calcite ultrafine mill performance characteristics:

  • 1. Efficient, energy saving
  • In the finished product fineness and motor power under the same circumstances, than the jet mill, mixing mill,ultrafine mill, ball mill production more than doubled.

  • 2 wearing parts long service life
  • Roller, grinding ring made of special materials forged, so that the degree of utilization greatly improved. In the case of the same fineness of the material and the finished product, the wear life of the impact crusher and the turbine crusher is 2-5 times longer than that of the wear parts, generally up to one year. The working life of the calcium carbonate and the calcite can reach up to 2 -5 years.

  • 3 high safety and reliability
  • Because there is no rolling bearing in the grinding chamber, no screw, so there is no bearing and its fragile seal, there is no loosening of the screw and the problem of destroying the machine.

  • 4. Product fineness
  • HGM tricyclic medium speed ultrafine grinding fineness of one-time product can reach D97≤5μm.

  • 5. Environmental protection, clean
  • The use of pulse dust collector to capture dust, muffler to reduce noise, with environmental protection, clean features.

  • 6.Compared with HGM8021 Calcite ultrafine mill output increased significantly.
