Abstract ball mass is an important parameter that is known to have an influence on the outcome of a mechanochemical reaction induced by ballmilling. a standard way of modifying the ball mass is to change the size of the ball made of the same material. in this case, however, a change in mass is accompanied by a simulatneous change in the ball size.

Ball milling is one of the few unit operation that improves with increasing mill diameter. if acceptable results can be obtained with a 12 jar mil, then good result will certainly be obtained with a 72 diameter mill. of course there is the possibility of over milling, obtaining a different particle size distribution or a need to change.
Beyond reduction in crystallite size, ball milling was found to increase the interfacial charge transfer resistance, lower the electrical conductivity, and produce aggregates that influenced performance. computations support that electrolyte diffusivity within the cathode and film thickness play a significant role in the electrode performance.
C closed circuit grinding also closely related to the ability of a ball mill to perform most effectively on a particular material size distribution is the increased grinding efficiency observed with increased circulating load and classifier efficiency.
