The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill

and with the decreased grain size, the necessary ball size also decreases (Olejnik, 2010; 2011) For each grain size there is an optimal ball size (Trumic et al, 2007) The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding In both
