ZGM/MPS Coal Pulverizer

Description

MPS & ZGM coal mill refers to the coal mill with working speed of 50-300r/min. MPS & ZGM coal pulverizer is the professional equipment for blast furnace iron making auxiliary material preparation processing, which can provide the suitable auxiliary material - coal powder for blast furnace iron making system. The medium speed coal mill is the most important large-scale equipment in the coal-to-oil pulverizing system, and plays an important role in operational safety and economy of coal-to-oil.

Working Principle

The electric motor drives the grinding disc through the reducer，wand the material enters the center of the grinding disc through the inlet of the lock wind feeder. Simultaneously, hot air enters the grinding disc through another inlet. As the grinding disc rotates, the material moves to the edge of the grinding disc under the action of centrifugal force and is crushed by the pressure of the grinding rollers when passing through the annular groove on the grinding disc. The crushed material is carried away from the edge of the grinding disc by the high-speed airflow, and the large particles fall directly back to the grinding disc to be crushed again. When the material in the airflow passes through the upper separator, the coarse powder falls from the cone bucket to the grinding disc for crushing again under the action of the rotating rotor, while the qualified fine powder leaves the grinding disc together with the airflow and is collected by the dust collection device to become the final product. For materials containing moisture, they are dried when they come in contact with the hot air stream. By adjusting the hot air temperature, it can meet the requirements of materials with different humidity to achieve the desired product moisture. By adjusting the separator, the coarseness and fineness required for different products can also be achieved.
