Vulco 174 Mill Lining Systems Weir

our elastomer laboratory experts are continually developing new compounds for improved mill liner performance and wear life. vulco compounds are produced for use across ag, sag, ball, rod and scrubber mills. options include impact resistant alloy inserts of cast and rolled metals for the most arduous grinding applications, or ceramic and rubber mill discharge designs to prevent grate rod mills are very similar to ball mills, except they use long rods for grinding media. the rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.sag mill is an investment that can produce handsome returns if extra production is needed or simply to give the mine the option to mill the hardest ores at design throughput rates. typical tests required to define a hardness variability function, are given below in figure the
