2001 The grinding operation in a ball mill is widely used in comminution. This process is extremely capital and energy intensive process and at the same time it is notoriously inefficient. Therefore, simulation can be used as a convenient tool in studying the behaviour and performance of grinding circuits by facilitating the evaluation of various scenarios and identification of optimum
