Mill Steel Charge Volume CalculationMilling Equations Montana State University

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 millMilling Equations Machining Time Peripheral Milling T m = L A f r T m = Machining Time Min L = Length of Cut A = Approach Distance f r = Feed Rate Dist/ Min Machining Time Face Milling T m = f r
