Ball Mill Footing Calculations
3 easy steps to calculate ball mill capacity
· Ball mill drum dimensions. Specify the length and capacity of the drum. If not available, specify the length and diameter of the drum. Step 3 (the final). Grinding bodies. Specify the weight of grinding bodies. You can simply specify a fill ratio for the drum if you do not know the exact weight of grinding bodies. Done!
