### 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 the media tumbling from the top of the pile (the shoulder) to the bottom (the toe ...

Cataracting at high speeds are used to convert potential energy into kinetic energy of impact on the toe of the charge and does not produce as much very fine material as the abrasive grinding of cascading at lower speeds. Most of the grinding in the mill takes place at the toe of the charge, where not only direct impact of the cataracting medium on the charge, but also the ore packed between ...
