    In a closed mill circuit the oversize particles are returned from the post milling processes to be remilled whereas with an open circuit the process has no feedback loop. In dry grinding systems, the material from conventional crushing and screening operations is subject to coarse and fine grinding primarily in roller mills or ball mills to reduce the material to the necessary product size range.

    Practical implications. It can be observed that for a ball mill circuit closed with cyclones, circuit relative capacity is not expected to increase significantly by increasing circulating load from 250% to 600%. This is because of the reduction in classification efficiency from 50% to 30% as calculated by Eq. (11).
