Similar to the ball mill work index, the rod mill work index is a tumbling test that includes both attrition and abrasion breakage mechanisms. Unlike the ball mill work index, the size of the feed to a rod mill test (10 mm–12 mm) is closer to the size of the crushing test.

W is the work index measured in a laboratory ball mill (kilowatt-hours per metric or short ton) P80 is the mill circuit product size in micrometers F80 is the mill circuit feed size in micrometers.

Eagle Iron Works' Attrition Mills are designed for highintensity, grainongrain scrubbing. As sand slurry enters the feed cell of the Attrition Mill, turbine blade propellers force the material grains to constantly abrade each other while moving the material from cell to cell within the machine, resulting in

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

The ball mill work index laboratory test is conducted by grinding an ore sample prepared to 100% passing 3.36 mm (6 mesh) to product size in the range of 45-150 µm (325-100 mesh), thus determining the ball mill work index (WiB or BWi).

3.6.1.1 Ball Milling A ball mill is a type of grinder used to grind and blend bulk material into QDs /nanosize using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell.
