Many industrial surveys have established that a significant portion of the total cost of metal production is expended in comminution processes. The grinding operation in a ball mill is a capital- and energy-intensive process. Hence, a marginal improvement in the efficiency of mill operation will be of immense economic benefit to the industry.
