### THE OPTIMAL BALL DIAMETER IN A 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
