We offer them with either a hammer mill or a ball mill. Our 45 tph system comes with a ball mill only. The hammer mill version of our turnkey ore processors is less initial cost, but higher maintenance cost (1015/ton, plus down time). It will produce ground material with 70% passing a 30 mesh screen and 50% passing a 50 mesh screen.
