How to calculate the grinding time of the ball mill

The pulp should have a volume of 18.5*25%=4.56m3 in the ball mill. Then the minimum grinding time = 4.56/1.35=3.38min Note: When the grinding time is the shortest grinding time, it is ideal when the large block is directly ground to the granule size, and there is no over-grinding phenomenon. This value is only for theoretical calculation. The average grinding time on site is higher than this value. The actual
