Calculate and Select Ball Mill Ball Size for Optimum Grinding
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and

CALCULATION OF MAXIMUM BALL SIZE FOR BALL MILL
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, thenreduce the feed size by using pre-grinding operation.
