How does slag Vertical roller mill work?

Slag enters the Vertical roller mill through a screw feeder. The material falls to the center of the mill under the action of gravity. The mill plate is connected with the reducer and rotates at a constant speed. The material is evenly distributed on the lining plate of the mill plate through the rotation of the mill plate. Under the pressure of the hydraulic system, the mill roller grinds the slag material and crushes it. .

Under the action of centrifugal force, the crushed slag is thrown to the edge of the mill plate, and most of the slag is blown back to the mill plate to continue grinding under the action of high-speed air in the wind ring. Some powdery materials rise to the separator with the high-speed gas through the middle shell of the mill. In this process, the material and the hot gas were fully exchanged, and the moisture was quickly evaporated, making the remaining moisture less than 1%. Material that has not yet been ground to the required requirements is selected by the separator and sent back to the mill plate for re-grinding. Material passing through the separator enters the dust collector with the air flow.
