Ball Charge and Grinding EfficiencyGrinding

In ball mills all the media is balls with a high SG so the impact of pooling is not as large Additionally in ball mills grinding is primarily through cascading not cataracting compared to an AG.SAG so the slurry pool is not a factor unless density is high which leads to viscosity issues.

Energy Use of Fine Grinding in Mineral Processing

In ball milling the product particle size distribution PSD can usually be modeled as being parallel to the feed PSD on a log linear plot When grinding to finer sizes in ball mills the parallel PSDs mean that large amounts of ultrafine particles are produced This consumes a large amount of grinding energy while producing particles which
