01062012 Besides particle size reduction, ball mills are also widely used for mixing, blending and dispersing, amorphisation of materials and mechanical alloying [1, 49, 51]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 efficienciesMODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLINGPlanetary ball mills are smaller than common ball mills, and are mainly used in laboratories for grinding sample material down to very small sizes Vibration mill Twin and threetube vibrating mills are driven by an unbalanced driveBall Mill an overview ScienceDirect Topics
