FINE GRINDING—DEVELOPMENTS IN CERAMIC MEDIA TECHNOLOGY 53 Introduction The high energy efficiency of stirred mills compared to ball mills is well understood within the industry. The use of tower mills as an energy efficient alternative to secondary and regrind ball milling became a standard flow sheet
The correct sizes are often determined by trial and error, primary grinding usually requiring a graded charge of 10-5 cm diameter balls, and secondary grinding requiring 5-2 cm. Concha et al. (1988) have developed a method to calculate ball mill charge by using a grinding circuit simulator with a model of ball wear in a tumbling mill.
The grinding performance is strongly affected by the size of grinding media (Stehr, 1988, ... Variables affecting the fine grinding of minerals using stirred mills. Minerals Engineering, 16 (2003), ... Ball mill simulation in wet grinding using a tumbling mill and its correlation to grinding rate.
