    Mill Speed Critical Speed

    Too fast and inefficient media movement (known as cataracting) will generate high impact but also greatly increase mill wear. Even faster speed will result in the media centrifuging inside the mill and virtually no milling or movement of media or product will occur. In most cases, the ideal mill speed will have themedia tumbling from the top of the pile (the shoulder) to the bottom (the toe) with many impacts…
