Ball Mill: The equipment to be used for size reduction is ball mill. The ball mill is kind of grinder used for intermediate or fine grinding. Ball mill is a metal cylinder which rotates about its horizontal axis. The coarse material charged along with the metal balls breaks to fine powder by impact of metal balls. 1
Ball mills also tend to have a greater reduction ratio as well as a lower rate of reduction, thus making them more preferable over other kinds of mills [2]. But like any of the other mills, as previously mentioned ball mills have a very low efficiency in terms of utilizing the energy generated towards particle size reduction. The diameter of ...
