Jan 01, 1983· Afton claims that the variable mill speed has been useful for preventing liner wear while processing soft ore (Pazour, 1978). Sydvaranger processes iron ore through a 21 by 33-foot variable speed ball mill. The speed range of this mill is from 62 to 82 percent of critical, with normal operating speed at 78 percent.

Table of ContentsVariable Speed DrivesDrive ReliabilityGrinding Circuit Capital Costs Large scale equipment can reduce both capital and operating costs for concentrators. Large semiautogenous mills can be effectively utilized in big mills but they must be kept fully loaded to take advantage of their great potential. With varying hardness ores, controlling throughput is difficult and careful
