Effect of Grinding Media on Milling
The size distribution of the balls in the mill charge appears to have no significant effect upon the size distribution of the product, nor upon the rate of grinding, provided that the size distribution of the balls is not too unreasonably chosen. Thus, no significant difference in the grinding characteristics can be detected in the published data on the subject between grinding with balls of uniform size and with balls …
Size Of Milling Media Affect Efficiency Of Ball Mill
In this figure, the negative influence of the smaller ball size on the milling efficiency is drawn by an arbitrary positive slope with ball size rather than the dependency of d 4, because in an actual dynamic ball mill situation, the balls already existing in the turbulent medium is moving rather than in stationary state, and thus the effect of the kinetic energy of the sedimenting balls on...
Effect of ball and feed particle size distribution on the ...
It was also observed from the experimental results that in order to increase the milling efficiency of a ball mill, towards optimum production of material in the desired size class, there is a need to correlate the ball size and the feed size distributions.
Factors Affecting Ball Mill 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 length to diameter ratios for a given power rating will yield different material retention times, the longer units being utilized for high reduction ratios, and the …

Ball Mill Loading - Dry Milling - Paul O. Abbe
As with most of the independent variable in ball milling it is best to do some empirical testing and then adjust your parameters. The starting point for ball mill media and solids charging generally starts as follows: 50% media charge; Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = …
