  • How Ball Mill Ore Feed Size Affects Tonnage Capacity

    Jul 26 2017  The grinding mill output will vary considerably with the Work Index If the feed size was 13 000 micrometers for the same grind production size theoretical output from Fig 21 would change from about 90 000 tons per day on the 13 Work Index down to 65 000 tons per day on the 16 Work Index.

  • Jet mill

    A jet mill grinds materials by using a high speed jet of compressed air or inert gas to impact particles into each other Jet mills can be designed to output particles below a certain size while continuing to mill particles above that size resulting in a narrow size distribution of the resulting product Particles leaving the mill can be separated from the gas stream by cyclonic separation.
