Understanding the Use of Ball Mills in Wet Grinding
The use of ball mills for wet grinding of various materials is a very common and efficient process. Ball mills are used to grind raw materials, ores and minerals (like lime or limestone) for flue desulphurization, coal and several other raw materials. Ball mills can be of two types, based on the different ways materials are discharged.

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.
