Milling Mineral Processing Extractives Hub. In the ASM sector, Stamp Mills are still in common use, especially in gold mining, but the efficient and m odern machines in widespread use are Tumbling Mills, the most common being Ball Mills, large rotating cylinders in which steel balls are loaded and cascade inside the mill as it rotates, effecting grinding.

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 of a mill’s energy budget.

Jan 01, 2009 1. Introduction. A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore. It was developed by Fred Bond in 1952 and modified in 1961 (JKMRC CO., 2006).This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding, and for ball mill.
