The ball charge and ore charge volume is a variable subject to what is the target for that operation The type of mill also is a factor as if it is an overflow mill subject to the diameter of the discharge port is usually up to about 4045 If it is a grate discharge you will have more flexibility of the total charge

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 The loading or change volume can then be read off the graph below orDetails
The cost of a ball mill conversion from overflow to grate discharge is ‘fairly’ affordable at 65000 for a 13′ x 15′ mill This is only for the discharge head grates and pulp filters rubber A comparison in laboratory of Overflow Discharge Ball Mill VS Grate Discharge Ball MillDetails
