Limestone ultrafine mill

Project Background

It is mainly suitable for ultra-fine powder processing of non-flammable and explosive brittle materials with medium

Limestone ultrafine mill for the material:

It is mainly suitable for ultra-fine powder 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 powder finished products in the 325-3000 mesh between the arbitrary regulation, the output of up to 0.7-7.5 tons per hour.

Limestone ultrafine mill features:

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.

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.

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.

Product fineness can reach D97≤5μm at one time.

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

Limestone ultrafine mill equipment components:

Limestone Mill - Complete set of stone processing equipment including hammer crusher, bucket elevator, storage hopper, vibrating feeder, micro-grinding machine, frequency classifier, double cyclone powder collector, pulse dust removal system, high pressure Fans, air compressors, electrical control system.

Limestone ultrafine mill works: At 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 through the processing of the three layers of 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.
