This model includes a phantom cyclone effect in the equations due to the ball mill being calculated by difference and not being calculated by the normal Bond equation The resultant operating work index of the ball mill will vary according to the ratio of the ball mill, rod mill and crushing work index values and is in the range of 80% of …
C = distance of centre of gravity or charge from centre of mill in feet a = dynamic angle of repose of the charge N = mill speed in RPM HP = A x B x C x L Where A = factor for diameter inside shell lining B = factor which includes effect of % loading and mill type C = factor for speed of mill
3.3 Ball Mill Design The ball mill designs also follow the Bond/Rowlings method with comparison with other methods. Again the method of use is the same 3.4 SAG/BM Combined design This is the combined model of the SAG and BM models. The difference is that a provision in the BM model allows for the fact that finished product is in the BM feed.
