The overflow type ball mill is suitable for fine grinding and operates in a closed circuit with a classifier. Grate Discharge Ball Mills: In this type of mill, the ground materials are discharged through the grate plate, which prevents the grinding media from exiting the mill. Grate discharge mills are used for coarse grinding.
In the conventional grinding process, the feeding particle size F 80 of rod mill or ball mill (80% of the particle size of materials entering the mill can pass through a certain sieve hole) is generally 12–25 mm, with high energy consumption per unit processing capacity. After the 1980s, a newly conventional grinding-classification circuit ...
