  • Calculation Of Residence Time In Ball Mill

    In ball mills where the grinding time is longer than in a VRM excessive powder flowability can lead to insufficient or inefficient grinding because the material flows too fast through the mill In contrast to ball mills VRMs have a very high internal circulation a short mill retention time and a huge number of classifying steps that carry.The modifications include ball mills and vertical mills as well as preheater kiln and cooler upgrades In case of a new calciner (new preheater) the retention time can be selected properly In case of upgrading projects the calciner volume can sometimes be increased to give improved retention time.
