Get PriceOften, the ball used in ball mills is oversize just in case. Well, this safety factor can cost you much in recovery andor mill liner wear and tear. Here is your Ball Mill DesignSizing Procedure. Calculation of top size grinding media Fred C. Bond Calculation of top size grinding media AZZARONIs Formula
the mill is used primarily to lift the load medium and charge. Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power.
Modern installations draw power of 210 MW. The power in kW required to turn a ball mill is approximated by P 0.285 d 1.073j m n where d is the internal diameter in metres, j is the fraction of the mill volume occupied by media, m is the total mass of media in the mill, in tonnes, and n is the mill speed, rpm.
