wet and dry ball mills

BatchBallMillGrinding. Capacities and efficiencies inwetanddryballmilling at different speeds and ore charges have been discussed in the foregoing pages. The results are summarized in table 16, which shows that in both capacity and efficiency grinding was at its best with small ore charges and high speed.
