  • Mill Grinding Wikipedia

    sag is an acronym for semi-autogenous grinding. sag mills are autogenous mills that also use grinding balls like a ball mill. sag mill is usually a primary or first stage grinder. sag mills use a ball charge of to 21%. the largest sag mill is in diameter, powered by a grinding is easily enabled in autogenous mills by attrition. also, autogenous mills have grate discharges, so as to retain the coarse grinding media in the mill while dispatching the fine particles. the other benefits of using autogenous grinding include reduction of metal wear, and elimination of secondary and tertiary crushing steps.autogenous grinding work is conducted in a separate pilot setup. the crude ore is crushed to a maximum size of in. and screened into sizes. the primary mill is ft. in diameter. the length can be varied from ft. to ft. in andor in. increments. the secondary grinding circuit uses a ft. diameter by ft. long pebble or ball mill.
