Comminution, which leads to liberation, includes two types of random and non-random breakages. The contribution of random and non-random breakage is very important in modelling the liberation phenomenon.After the crushing process a ball mill is one of the most important equipment used for secondary grinding. Size reduction is carried out through Impact of the balls, this is the main working principle of a Ball mill. The cost of installation and the consumed power in a ball mill is much lower which makes it very economical in a grinding circuit.
