Closed circuit ball mill – Basics revisited - ScienceDirect

Apr 01, 2013· 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).Cited by: 14

Ball Mills - an overview | ScienceDirect Topics

For many decades the two-compartment ball mill in closed circuit with a high-efficiency separator has been the mill of choice. In the last decade vertical mills have taken an increasing share of the cement milling market, not least because the specific power consumption of vertical mills is about 30% less than that of ball mills and for finely ground cement less still.
