Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed. Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speed range.

The torque distribution on liners and baffles is affected by lifter height, lifter number, and mill speed. • The changes in the torque and power of a ball mill can be effectively explained using two factors: lifter and particle area ratio.
torque caracteristic of ball mill afvalcontainers-catco. DEM is a highly convenient approach to determine the particle behaviour, torque, and power draw of ball mills in different conditions. Consequently, DEM is used in the present study as a tool to examine the effect of lifters and mill speed on the particle behaviour, torque, and power draw ...
For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
The ball mill has a constant speed, so the torque distribution coefficient of the SMCPMSM is the load power distribution coefficient. l = P s e t / P (17) where l is the torque distribution coefficient; P s e t is the target load power of the system and P is the load power of one module.

The problem with ball mills vs a simulation like ETAP is that the mill initially is a torque load that is dependent on rotation angle until the charge start to tumble. ETAP only simulates the torque vs speed as a curve. Best bet would be to use a torque peak right off zero speed and then drop down to a more constant torque type of load curve.
