Ball mills with two different sizes were considered in this study, one small and another large. The simulations with the two mills have the same conditions as the real ones by Valderrama et al. (1996) and Kalala and Moys (2004), respectively, in terms of mill size, particle size, mill speed fraction (mill speed as a fraction of critical speed) and fill level fraction.

Key considerations. Numerous factors must be considered when selecting a mill liner design, including required grinding action, mill size as well as ore and grinding media characteristics, among others. These considerations will help determine the best liner material and geometry. Depending on the mill size and material being ground, a lining ...

Unless you have used a different and harder material, if the grinding process slows down or yields lesser output as compared to normal, it may be an indication that your ball mill liners may need a change because they may be internally damaged. You should keep a track of your time period and output to keep a lookout.

Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners. Typically, a ball mill lining has a more rounded profile, often like a sine wave, and the size of the waves is selected based on the size of grinding media used.
