The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x ...

The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out.

A trommel is a rotary cylindrical structure that is rigidly attached to the discharge end of a mill. The intended operation of the trommel is shown schematically in Fig. 1.It contains moulded screen panels or wire mesh and can have different aperture configurations in each axial section depending on the intended duty.
