2018-5-10speed of a mill is typically in the range of 74 to 78 of the critical mill speed. This is a direct function of the mill diameter, which means that the rated speed for mills of the same diameter do not vary significantly. Therefore, the higher power density values discussed above, consequently lead to higher torque density values within these GMDs.
