Many older operations have rod mills in combination with ball mills. Ball mills are a similar shape to that of the rod mills except that they are shorter with length to diameter ratios of 1 to 1.5. As the name implies, the grinding media in these mills are steel balls. The particles size of the feed usually does not exceed 2.5 cm.
In some plants a ball-mill or rod-mill will reduce the ore to, say, 100 mesh and a tube-mill will finish the grinding to 200 mesh or finer. ... but it must be fed with fine ore—say, 1/8 to ¼ inch—to do this properly. Grinding coarse ore in a ball-mill is done by steel balls of three sizes (5, 4, and 3 inches); fine ore is ground in a tube ...

2. Grinding system: Ball mills grind fine ore rocks into a fine powder to release the gold in the rocks. Then, the output material enters the spiral classifier for classification. The large-grained minerals are returned to the ball mill for re-grinding to ensure that 80% of the final output is less than 200 mesh (0.074mm). 3.
