2009-6-1 At product sizes finer than 80% passing 75 μm, the efficiency of ball mill grinding rapidly decreases. The practical limit to ball mill product fineness is considered to be 40–45 μm (Gao and Weller, 1994). Although ball mills can still be found in the regrind circuits in a number of mineral processing plants, their energy consumption isget price

Dec 18, 2013 fine grinding, to p80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. this grinding is typically done using stirred mills such as the isamill or stirred media detritor. while fine grinding consumes less energy than primary grinding, it can still account for a substantial part get price
2019-5-10 Factors Influence Ore Grinding Mill Efficiency. According to statistics, the energy consumption of the crushing and grinding operation accounts for about 65% ~ 75% of the total energy consumption of the concentrator, and the steel consumption accounts for almost 100%. Therefore, it is of great economic and social benefit to correctly selectget price
