The amount of products in size of -106 micron during different residence times in ball mill and accompanied circulating load ratios were given in Fig. 5. Based on the values shown in Fig. 5, the CLRs were determined as 0, 8, 70, 150, 270 and 480 % for the residence times of 40, 30, 12, 6, 4 and 2.5 mins,

or revolution ( ), which represent a circulating load of 250%. This is on the premise that more ball mill spins will produce finer particles, and therefore less circulating load (circulating load=coarse particles/fines particles). Usually after eight grinding cycles the process stabilizes at circulating load values close to 250%.
