Oct 25 2017 The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency a Mill Geometry and Speed – Bond 1954 observed grinding efficiency to be a function of ball mill diameter and established empirical relationships for recommended media size and mill speed that take this factor into account.
Ball Mills are generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers such as screens spiral.

The balls and material of the ball mill tank should have the same weight to achieve stable operation improve the grinding efficiency and reduce the vibration of the ball mill. Two ball mill jar grinding experiments can also be used when there is insufficient material.
Nov 27 2020 A ball mill rotates its long shaft and drive a jar which is placed on it. The friction of the rubber surface of the shaft can rotate the jar. The grinding beads grinding balls in the jar will constantly hit the sample due to gravity and mechanical force. After a long period of rotation and impact the sample gradually changes from large pieces to small pieces and small pieces to powder.
