Indeed, in four to seven weeks of operation, a SAG-ball mill circuit can consume the same weight in steel used to construct the entire milling circuit structure. Improving the wear life of mill liners is one way to tackle indirect energy consumption; it also improves mill productivity as downtime for liner replacement is reduced.

Grinding media consisting of steel balls, with typical diameters from 25 to 75 mm, is already present in the mill along with any rock that has not yet overflowed through the discharge end. Typical power consumption for a 5-m diameter by 7-m-long ball mill is between 2.5 and 3.5 MW.

As one of the commonly used equipment in mineral processing plants, the number and proportion of steel balls in the ball mill affect not only the grinding efficiency and …

continuous ball mills. In an experiment conducted using a wet laboratory continuous ball mill filled with pebbles, cyl-inders and balls of equivalent volume and a 95% calcite feed combined with a 5% quartz, ball load, density and shape were varied. It was shown that decreasing the ball load by 0.5 by weight also decreased the residence …
