How To Calculate Ball Mill Volume Loading Volume Calculation For Ball Mill 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
Get PriceRod mills are very similar to ball mills except they use long rods for grinding media The rods grind the ore by tumbling within the the mill similar to the grinding balls in a ball mill Rod mills normally carry 35 to 65 rod charge by volume
