the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure Ad this can be used to establish the essential features of a model for mill
Stirred mills were first introduced in the 1950`s as an alternative to ball mills in a regrind application. Since then they have been used to grind a range of materials from limestone to coal to sulfide concentrates. A laboratory tower mill was used to investigate the effect of some variables on the power requirements of a plant mill.

The ball mill is very similar to the SAG mill, except it has a larger proportion of steel balls to assist in the grinding process. Following grinding in the ball mill, the material is returned via the sump (8) to the secondary hydrocyclone (9) for resizing.
Grinding in small plants, as in larger installations, has proven to be the most costly of all unit operations from both capital and operating standpoints. Therefore, grinding deserves the most scrutiny of all operations during the design procedure. A recent survey by a major grinding mill manufacturer reveals that more than 80 autogenous or semiautogenous mills having between 100 and 1,000
