    Sep 27, 2012 crushing is to feed some coarse ores directly to wet or dry semiautogenous or autogenous grinding mills. (using larger pieces of the ore to grind/mill the smaller pieces), then to pebble or ball mills. Ideally, the liberated particles of iron minerals and barren gangue should be removed from the grinding circuits

    Mar 19, 2017 In the handling of wet, sticky ores such as encountered in tropical areas having distinct dry and rainy seasons, the crushing plant is a section of the mill which must be planned very carefully. Unless this is done, crushing becomes a constant source of trouble resulting in lost production and high milling cost.

  • The Effect of Ball Size Diameter on Milling Performance OMICS

    Approximately only about 20% of the energy generated by the mill is utilized for actual grinding of the ore [2]. This inefficiency is a result of various factors such mill load, rotation speed, type of milling (wet or dry) as well as the size of the steel balls [3]. Mills are also one of the largest energy consumers in processing plants

    Autogenous or autogenic mills are socalled due to the selfgrinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles. It is similar in operation to a SAG mill as described below but does not use steel balls in
