Besides the ball mill that we used, there are several other devices can be used to reduce the size. There are cutter mill, hammer mill, vibration mill, roller mill and fluid energy mill. Cutter mill is an equipment that used the principal of cutting method whereby it able to produce the particle size from the range of 100µm up to 100 000µm.For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower.
