The ball mill slakers are much more expensive than paste or slurry slakers. They are available in sizes ranging from 1000lb/hr to 50 tons/hr. Figure 3 shows an attritor type vertical ball mill lime slaker. The ball mill slakers are equipped with an external classifier, which separates slurry from the oversized grit and impurities. The oversize ...

The ball mill made about one revolution after the power was turned off, and just as soon as the mill stopped, a spout was placed at the discharge trunnion and all of the pulp that flowed out of the mill was caught in tanks. The manhole in the mill was then opened and the whole mill charge dumped into other tanks.

The pilot mill is also equipped with a sensor measuring the 'ball and pulp toe and shoulder angles' (see Figure 3). These data are then used to calculate the total pulp and ball charge angle (see Graph 5). Graph 5 clearly illustrates how the ball charge stays quite compact till about 73% solids as the total media angle does not change.

provides capital and operating cost estimates for each of the comminution circuits . The results showed that the HPGR - ball mill circuit achieved a 21% reduction in energ y consumption over the existing SAG - ball mill circuit at the same P 80 grind size of 160 µm. At a grind of 80% passing 75 µm, the HPGR - stirred mill
