For efficient operation of ball mills necessary to observe the right balance between balls size and feed material size. If the feed material contains many large lumps and grinding balls can’t crush them, it leads to a gradual accumulation them between the balls. As a result, mill suspends own operation. In these cases, need to reduce the size of crushed material or increase the size of the

For the feed sample sizes investigated, the three ball mix was more effective for the coarser feed due to the presence of the 50 mm balls whilst with a finer feed the binary mix gave the optimal amount of size class of interest. These results prove that a close control of feed and ball match is of paramount importance if one is to improve the efficiency of milling circuits.
