Types of Ball Mill. There are several types of ball mill grinding machines, each designed for specific applications. The most common types include: Overflow Ball Mills: These mills have a horizontal cylindrical shell with an outlet at one end. The materials are fed into the mill through the hollow trunnion at the other end.

Rod mills generate small amounts of fines, as fine particles typically accumulate in the space between rods without enduring comminution [2]. Effective grinding of this material occurs in the ball mill compartment, generating finer fragmentation. The Bond Rod Mill Work Index (BRMWI) test was only possible for Blend 5 (Table 2) due to excessive
