result in mills operating at optimum speed if low media charge or low consistency is used in the mill. The use of lifter bars welded or bolted to the mill cylinder in unlined mills reduces media slippage in mills whose rotational velocity is slow. Lifter bars are recommended when the grinding media charge is below 45 percent of the mill volume.

Effect of ball and feed particle size distribution on the ...
Jun 01, 2018· Khumalo et al., 2006 postulated that generally larger sized grinding media would break larger particles quicker but a finer product would be obtained by use of smaller balls. However, use of smaller grinding media is believed to support abrasion and attrition (Katubilwa et al., 2011) which are energy inefficient breakage mechanisms .

Optimization of mill performance by using
Studying the complete evolution of the media angle (βynamic) through the liner lifetime can lead to an improved liner design. However, the example of liner design and grinding efficiency uses the media charge angle only. Other examples will explore the interaction between the pulp and the media load. Influence of slurry properties and load ...
