Small particle size in the order of micrometer of event nanometer size is preferred. The raw materials were ground from the big particle size to the smallest possible by using multistep grinding. In the laboratory, the common method to be used as the ball mill. This work aims to design a simple horizontal ball mill.

The same cylpebs size distribution and load were assumed to be applied in the second compartment of the new mill design. Simulation result showed that, 10% capacity increase can be achieved with 16% material retained on 0.045 mm in the mill discharge when the mill was converted to a two-compartment mill.

was to locate the variation of ball filling in the mill. Ball Charge Program Abrasion In this section, ball abrasion was calculated via manufacture`s ball charge program.
