    TECHNICAL NOTES 8 GRINDING R. P. King. 8-2 &ROOLVLRQ 5ROOLQJ ZLWK QLSSLQJ The critical speed of the mill, & c, is defined as the speed at which a single ball will just remain against the wall for a full cycle. steel balls in a ball mill, or large lumps of ore in an

  • Ball Mill Critical Speed & Working Principle

    19-6-2015· If 75 percent of critical speed is considered desirable for efficient grinding in a 2.4 meter (8 foot) diameter mill, then the same will be true for a 5.0 meter (15½ foot) diameter mill. At least in terms of effective charge motion, then, there is no justification for resorting to lower mill critical speeds at larger mill diameters.
