ball mill loading by volume percent

20 08 2017  Thinner mill liners result in a larger volume inside the mill This means you can have a higher charge level Using composite liners also cuts the weight of the liners to about 50 percent of standard steel cast liners making it possible to work with a higher ball charge level without increasing the total weight of the mill.
