The larger the diameter is, the slower the rotation will be. Ball Mills are generally used to grind material ¼" and finer, down to the particle size of 20 - 75 microns. To achieve reasonable efficiency, the ball mills are to be operated in a closed system, with oversize particles continuously being re-circulated back to the mill and to be reduced.


Ball Mill Introduction. Ball mill works on the principle of impact: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. it is partially filled with balls.
