ing media charge. It is important to stress, however, that a simultaneous slippage-free mill charge movement was supposed. With smooth liners and especially with wet grinding this is not the case. So, for example, in his cited paper Uggla (1930) described and explained periodical backwards slippage of the charge. To avoidDuring mill shutdowns, the mills should be periodically surveyed and the actual charge level observed. There is guidance in Moly Cop tools for doing this (spreadsheet: Media Charge level), where three methods are supported: Free height; Chord length; Number of exposed lifters; Charge monitoring. A control chart of mill power draw should be ...CHARGING GRINDING MEDIA - Grinding & Classification Circuits ...The media used in the charge generally describes a tubular mill. Thus, the medium could be steel or cast iron balls when the mill is designated as a ball mill, or it could be steel rods where the mill is known as a rod mill.When no grinding medium is charged it is known as an autogenous mill.Tubular Ball Mills - ScienceDirectاحصل على السعر
