CALCULATION OF MAXIMUM BALL SIZE FOR BALL MILL GRINDING

Jun 15, 2018%age of mill in critical speed = 70%. Specific gravity of the feed = 2.2 gm/cm3. Mill effective diameter = 2.23 m. 335 is a constant used for dry grinding with steel balls in the mill. Actual size of media is taken is lower than the calculated value. It is around 80 to 90 mm. If you Wants to reduce the maximum ball size, then reduce the feed size by using pre-grinding operation.
