10 difference between bowl mill and ball tube mill

  • Cement Kilns: Size Reduction and Grinding

    Rawmill systems typically require a feed of maximum size 510 cm, so a crushing stage is first required. In the kiln, the finelydivided rawmix is sintered, The reliance on pebble media during this period helped preserve the distinction between "ball mills" and "tube mills".
