rpm optimal ball mill
What is the optimal speed for a ball mill?
The optimal speed for a ball mill is typically referred to as the "critical speed," where the balls are carried to the top of the mill and then cascade down. This critical speed is usually around 65-75% of the mill's critical speed, depending
