The way in which the mill liners tumble the ball charge determines how the balls will grind the ore and the liners themselves wear. Tumbling characteristics of the grinding media is determined by height, slope and radius of curvature of the liner surface. Hence the design of,Energy Use of Fine Grinding in Mineral Processing,,18/12/2013· 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 of a mill’s energy budget.Ball Mill Design/Power Calculation - 911 Metallurgist,19/06/2015· If P is less than 80% passing 70 microns, power consumption will be; Ball Mill Power Calculation Example #1.
