Practically, mill speed between 68 and 82% of critical speed. % critical speed is the mill actual speed in RPM divided by nc. Example: 3.98 meter mill with rotational speed of 15.6 rpm then nc = 21.2, % critical speed = 73.6 %. TO DOWNLOAD THE EXCEL SHEET AND ALL THE OTHER USEFUL BOOKS AND RESOURCES KINDLY CLICK HERE

CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

EF5BM=[ P80+10.3 1.145×P80] ( 3 ) The EF4 formula requires both the rod mill and ball mill work index (rod mill Wi is used to calculate the optimal feed size) and because this is a "single-stage ball mill" calculation, the F80 is actually the rod mill feed size (10,000 µm) from Table 1 and the P80 is the ball mill circuit product. The EF5 factor only applies …

Then in ball-wear formula (25), T = 6.9/K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = 6.9Wt/Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/6.9Wt are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.

of a mill, which is related to the mill load. If a particular mill mass setting creates poor mill performance, then a new mass set-point will be needed in order to maximize power draw. A PID controller is able to control only at the given set-point, and is unable to recognize such a development in the circuit. It is also incapable of self-tuning.

ball-on-shell impacts just above the charge toe, owing to the risk of ball-on-liner damage and excessive metal flow. In fixed-speed mills, this may be achieved by increasing charge volume; in variable speed mills, this may be achieved by reducing mill speed; and in both cases this may be achieved by design by increasing the lifter face angle.
