The separation will become easy with the liberation process. In the present study the Grinding characteristics of the Bauxite ore were studied by using the ball mill.ball milled bauxite,Ball milled bauxite residue as a reinforcing filler in phosphate-based .Bauxite residue (BR) is an alumina refinery waste with a global disposal problem. Of the 120 MT generated annually, only 3 MT is disposed via utilization. One of the significant challenges to sustainable utilization has been found to be the cost of processing. In this work, using ball milling, we achieved material modification.

Ball mill - WikipediaA ball mill is a type of grinder used to grind and blend 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. A ball mill consists of a hollow.ball milled bauxite,The Votorantim Metais bauxite rod-ball grinding mill - ICSOBAthe grinding phenomena of this mix in a rod-ball mill. For this evaluation several laboratory tests were executed and a model was calibrated. This model was compared with in field information and process alterations were suggested.
