Apr 09, 2015 Product size can be as small as 0.005 mm, but product size is dependent upon the time the charge spends in the grinding zone and therefore the reduction rate is a function of the throughput. The speed of rotation is optimum at about 75 % of critical speed. Some mills are compartmentalized with each subsequent section having a smaller ball size.
