Ball Mill - an overview ScienceDirect Topics

Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.

MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING

2018-12-9  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.
