The weight of balls is kept constant and size of balls depends upon the size of feed and mill. Working: speed of ball mill. The material to be reduced in size is entered into the machine through a hopper. The electrical supply to the machine is started after a careful closure of the machine feed. The mill is rotated at optimum speed.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.
