Then, cone crushers make the pieces even tinier, getting the ore ready for the next steps. Next up is grinding, which is done in special mills like grinding mills, ball mills, or rod mills, depending on what we need. The goal is to get the ore just the right size so we can get as much valuable stuff out of it as possible.
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. In other plants a ball- mill or a tube-mill will do all the grinding, but it must be fed …
Rod Mill Fines Content. The presence of "fines" in open circuit rod mill feed has long been recognized as an important factor for both stable and efficient mill operation. Although addition of extra fines to rod mill feed was common practice in the past, few details have been reported. The fortunate exception is the experience at Frood Stobie.
When calculating rod mill power for a rod mill-ball mill circuit, do not allow for improvement in the ball mill performance due to receiving rod mill feed. If the rod mill feed is produced with open circuit crushing, apply a 1.2 inefficiency factor to the power calculated for the rod milling stage only.

This method is popularly employed in fine grinding processes such as ball mills or rod mills. In these mills, the material is blended with grinding media, for instance, balls or rods made of steel. The rotation of the mill makes the media grind and wear out the material, thus lowering its size in stages.
