However, in this situation the ball mill has to supply this energy and it has a different (higher) work index than the crusher (ie the ball mill is less energy efficient than a crusher and has to input more energy to do the same amount of size reduction). Hence from equation 7, to crush to the ball mill
Pebble mills are a type of ball mill and are also used to reduce the size of hard materials, down to 1 micron or less. Because of their fairly simple design, ball mills and pebble mills are less likely to need costly repairs (unlike other crushing or extraction equipment) making them an attractive option for businesses on a budget.
