You are working in a company produces limestone and handling a stone size reduction process using ball mill to break stone at average 6 mm to smaller size. During the process, many fine particles are produced due to attrition effect. These fine particles are to be removed to reduce dust hazard and ensure quality of product.

A ball mill is a type of grinder used to grind or 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 cylindrical shell rotating about its axis. T

Sep 01, 1989· Int. J. Miner. Process., 27: 125-132. The grindability of an ore in the process of mineral dressing can be determined by use of the Bond work index (Wi). This index is determined on a laboratory-scale using a Bond ball-mill and by simulating dry grinding in a closed circuit until the 250% circulating load has been obtained.
