The starting point for ball mill media and liquid charging is generally 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% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58% ...

A series of wet grinding experiments have been carried out using a stirred ball mill to systematically investigate the effect of processing conditions on the final particle size distribution and grinding kinetics. A sub-micron particle size down to 350 nm was achieved, while the grinding energy efficiency or enhanced grinding rate was shown to be …

Based on tests performed with different amount of water as milling additive, 25% was determined to be the optimum. When water was increased to about 50%, powder started to stick to the wall of the ball mill vial and milling was adversely affected. In wet milling, a powder water ratio of 1:10–15 was found more effective.
