Fig. 10, Fig. 11 results obtained by us on variation of S ** with ball load for 70% and 55% critical mill speed. It can be seen that at 70% critical speed the maximum S ** value is observed at a J value of about, while at 55% critical speed the maximum value is observed at a J value of about
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and nonferrous metals. The ball mill can grind various ores and other materials either wet or dry.

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell''s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical ...
The Critical Speed is used for the determination of ball mill ideal operating speed. But for comparison, rod mills would operate between 50% to 95% of the critical speed. The faster the mill speed, the greater the wear on the rods and liners.
The critical speed of a SAG mill is the speed in RPM''s at which centrifugal force causes the material being ground to be held against the inside of the shell. ... When setting up a ball mill, it ...
