SAG Mill Control . SAG mills can be optimized for maximum ore throughput or maximum grinding energy efficiency. In both cases, precise control of the mill filling percentage is critical (Wills and Napier-Munn, 2006). Maintaining constant mill weight, as indicated by bearing pressure, is one approach to stabilize the mill

SAG mill feed is at its maximum, mill density is high and bearing pressure remains low; SAG mill feed is at its, For example, as ore size increases, the strategy will seek to run lower bearing pressure to maximize the lifting of the larg. Read More
