There exists a speed of rotation (the "critical speed") at which the contents of the mill would simply ride over the roof of the mill due to centrifugal action. The critical speed (rpm) is given by: nC = 42.29/√d, where d is the internal diameter in metres. Ball mills are normally operated at around 75% of critical speed, so a mill with.
Each mill has its optimum circulation loading which is determined from operation at different total feed set-points and will be higher for large diameter mill, large separator and use of additive. 16/10/2007.

The closed-circuit grinding system, all ground materials are led into a separator and classified into refined powder (products) and coarse powder (return powder). The coarse powder is returned to the ball mill and ground again with newly-fed raw materials. Following benefits can be realized with this technology: Grinding.
