To understand the discharge of calcite mill, you must first understand the whole operation process of calcite mill, the main motor of calcite mill drives the spindle and turntable to rotate through the speed reducer, and the roller pins on the edge of the turntable drive dozens of grinding rollers to roll in the grinding ring. The large lumpy material is crushed into small particles by the hammer breaker and then sent into the storage bin by the elevator, and the material is evenly sent to the bulk disk on the upper part of the turntable through the vibrating feeder and the inclined feeding pipe.

Calcite Grinding Mill

Calcite Grinding Mill

The material is dispersed around the circle under the action of centrifugal force and falls into the grinding ring raceway, which is impacted, rolled and grinded by the ring rollers and becomes powder through the processing of three layers of ring raceway. The high-pressure blower sucks in the external air into the machine through suction and brings the crushed material into the powder separator. The rotating impeller in the separator makes the coarse material fall back and regrind, and the fine powder that meets the requirements enters the cyclone collector with the airflow and is discharged by the lower discharge valve, which is the finished product; and the airflow of fine dust is purified by the pulse dust collector and then discharged through the blower and muffler.

Calcite mill is to crush and grind the large ore from the mine to get the product with smaller particle size, and to provide a certain particle size for the crushing and grinding process, which is the grinding task. For grinding operations, the larger the product particle size, the higher the productivity of crushing and grinding powder, and the lower the cost of grinding. However, for grinding production, the production capacity of the grinding equipment is reduced with the increase of stone particle size, on the contrary, if the particle size of the given stone is reduced, the production capacity can be increased, and the cost of grinding can be reduced. In general, the energy consumption after crushed ore crushing is less, while the energy consumption after crushing is large. In re-determining the reasonable size of crushed ore, it is mainly related to the size of the mineral processing plant, the crushing equipment used, the crushing process used and other factors. According to the principle of "more crushing and less grinding", it should be appropriate to obtain small crushed ore particles.
