Dear Groves,
 

Take kefid vertical mill as an example: the main motor through the reducer drive disc rotation, while the wind from the inlet into the mill, the material by the screw feeder under the mouth of the middle of the disc, under the action of centrifugal force, the material From the center of the disc to the edge of the uniform movement, through the grinding wheel on the grinding roller area, by the roller rolling, large pieces of material directly crushed, the fine material by the extrusion of the bed after the formation of intergranular crushing.
 

The crushed material continues to move toward the edge of the disc until it is removed by the strong airflow at the air ring, and the larger particles are re-dropped onto the disc to continue crushing. The material in the air stream passes through the upper separator, Separate the role of the blade, the coarse particles back to the grinding mill on the grinding, qualified fine powder with the air together with the grinding, the system collector to collect, was collected powder is ultra-fine grinding mill product.
 

Mixed with the material of iron and other debris with the material movement to the edge of the disc, because of its own weight can not be blown by the wind, fell to the bottom of the mill was installed in the bottom of the disc scraping plate scraped into the slag discharge.
 

Regards!
