Grate Discharge Ball Mill: This type of mill usually works with a high circulating load and thus produces very little extreme fines. The specific power consumption is therefore less than for an Overflow Mill. A Grate Discharge Mill will also have 15—25 % higher capacity per volume unit as compared with an Overflow Mill.
