Get Pricemar 19, 2017 We can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media. while the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
Get Pricemaximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. figure shows that there is no linear relation between mill absorbed power and ball filling degree.
