5 Ways To Improve Grinding Efficiency Of Ball Mills – News

Dec 26, 2017 · Mill Geometry And Speed. According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed. Ball mills with different length to diameter ratios for a particular power rating will produce different material retention times.

Total primary milling cost reduction by improved liner design

In primary high ball load milling, the grinding media plays the biggest role in total milling cost. This cost can be drastically reduced by improving the impact condition inside the mill. The impact condition inside the mill is influenced by shell liner design (as well as feed end and discharge design) and the type of discharge.
