MODULE 5 FUNCTIONAL PERFOMANCE OF BALL

For any process, including ball mill circuits, we can say that output equals input multiplied by efficiency. Output Input x Efficiency In a ball mill circuit, the output can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies.
