Jun 25 2018 · 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.
It was also observed from the experimental results that in order to increase the milling efficiency of a ball mill towards optimum production of material in the desired size class there is a need to correlate the ball size and the feed size distributions.
