Stirred Media Mills In The Mining Industry Material

jun 01, 2020 the ball mill standard grindability test utilises a particular lab-scale ball mill, with dimensions of 305 mm internal diameter and 305 mm length, and 20.125 kg of steel media with a specified distribution of different sizes.ball size vs. grindability. It has been recognized that the grindability of an ore in a ball mill is a function of both feed and mill parameters: work index, largest particle size and size distribution; density of solids and slurry; mill diameter; rotational speed; rowland and kjos defined the largest ball size needed based on these this grindability test or bond ball mill work index procedure is used to determine the bond work index of minus six mesh or finer feed ore samples. these equation application methods are used to process ore samples in a ball mill using a standard ball charge. below describes in general terms the bond work index procedure used by a professional metallurgical testing laboratory.
