Grinding analysis of Indian coal using response surface

It is clear from figure that number of balls on fineness has dominant effect than grinding time. With more number of balls and less grinding time one can produce more fine powder. The figure reflects that process will be inefficient if ball mill is operated between 11 and 16 number of balls and 4 to 5.9 min grinding time.Get price
