MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING

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. There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill.
