The chunks of material are crushed to the required granularity by the hammer crusher and then sent to the bunker by the hoisting machine. The materials are fed into the host machine through the feeding equipment in an even and continuous manner. The material entering the host machine falls onto the upper part of the host turntable with the inclined draft tube On the bulk tray.
When the host is working, dozens of grinding rollers rotate in the loop and roll. The material in the role of centrifugal force scattered by scattered around the plate and into the grinding chamber, grinding ring in the ring stamping, rolling, grinding.
After multi-layer crushed and milled material, with the fan air flow into the separator for powder classification, under the action of the separator impeller, the material does not meet the fineness requirements fall back into the mill cavity and re-grinding, in line with the fine Degree of the required material will then enter the cyclone powder collector with the separation of part of the powder collected by the bottom of the discharge device is the finished product powder discharge. The rest part of the powder from the cyclone dust collector into the upper part of the pulse dust collector, and adhesion to the surface of the filter bag, pulse valve to control the high-pressure airflow blowing instantaneously to the inside of the filter bag caused by the dramatic expansion and fluctuation of the filter bag, through the filter bag Suddenly jitter bounce off the adhesion of the powder, falling powder in the lower part of the precipitator, the two collected by the screw conveyor to collect the discharge is the finished product. After filtering the air flow through the muffler discharge to the air. The system is an open system, operating under negative pressure.
New design of the grinding roller grinding curve, to enhance the grinding efficiency. In the finished product fineness and power of the same circumstances, the production capacity than the jet mill, mixing mill, ball mill and other high doubled. Product fineness can reach d97≤5μm at one time.
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 service life of the wearing parts is 2-3 times longer than that of the impact crusher and the turbine crusher, and the service life of the calcium carbonate and the calcite can be 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.
Can be widely used in calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomaceous earth, heavy Spar, gypsum, alunite, graphite, fluorite, phosphate rock, potassium ore, pumice and other materials more than 100 kinds of grinding.
The use of pulse dust remover and muffler can reduce the dust pollution, reduce noise, meet the national environmental standards, the surrounding environment without pollution.
