Fig. 8 shows that the small 10 mm ball size is superior in generating more material in the fines size class, from both feed sizes used. If an objective function was to maximize the production of fines e.g. in the cement industry, the A.R shows that use of smaller ball sizes would give superior results.

The fineness of any sieve or screen depends upon the width of the wire used. The wire used in 10 mesh sieve will be thicker than the wire used in 60 mesh sieve. A thick wire can't make a fine sieve and a thin wire can't make a thick sieve. Fine sieves above 400 mesh, the particle size is described in microns.

The action of ball mill is very simple. The material to be ground is fed from the top. When the mill is rotate about its horizontal axis, the steel balls strike against the perforate curve plates and in doing so, they crush the materials. This crush material passes through an inner sieve plate and then through an outer sieve plate.
