And practices prove that the unit energy consumption of wet ball mill can reduce to some degree after adopting the rubber scaleboard, it usually can reduce 10%. What's more, the service life of the rubber scaleboard is 2 or 3 times longer than the alloy scaleboard.The most remarkable thing is that besides reducing energy consumption, the rubber scaleboard can also …

Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
