is ball mill a closed system

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
