For the greatest particle size reduction, ball mills should be operated at their optimal speed. This speed is normally between 50-90% of the critical speed, which is dependent on the application and material to be ground. At the optimum speed, the grinding media falls down the shell of the mill at the highest point thereby generating the ...
