This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by xm = k1d2. The variation of a with ball diameter was found to be of the form a = k2 / d1.5. Both k1 and k2 vary with mill diameter, and simple power laws have been assumed, k1 ∝ D0.1, k2 ∝ D0.6.

2013-12-01 The ball diameter of 5 mm is optimal at 50 rpm of rotation speed (the resultant average particle size of the milled powder is 2.3 μm), ball diameter of 3 mm is optimal at 100 rpm (1.4 μm), and 2 mm is optimal at 153 rpm (0.84 μm).

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. As well, mills with different ...
