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 12 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.

Solutions european ball mill iron ore pdf design and fabrication.Pdf design and fabrication of mini ball mill, design and fabrication of mini ball mill methodology journal of the european ceramic society 2015 as well as on the basis of the experiment carried out on grinding quartz and copper ore european ball mill.

Objective the objectives of this experiment are to demonstrate a batch cylindrical ball mill operation and to demonstrate a sieve shaker operation and familiarized with screen analysis introduction size reduction is an operation that carried out for reducing the size of bigger particles into smaller one of desired size and shape with the help of external forces.

Rod mills are very similar to ball mills, except they use long rods for grinding media.The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill.To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.

Bond rod mill grindability test.The test determines the bond rod mill work index which is used with bonds third theory of comminution to calculate net power requirements when sizing ball mills.Various correction factors may have to be applied.The test is a closed-circuit dry grindability test performed in a standard rod mill.
