Working principle and characteristics of vertical mill
The working principle of a vertical mill involves the rotation of a grinding table with rollers attached to it. Raw materials are fed into the table and ground between the rollers and table. The ground materials are then blown by hot air through an outlet in the mill's casing. The force generated by this process creates pressure on the grinding ...
