SAG Mill Grinding Circuit Design

SEMI AUTOGENOUS DESIGN FACTORSSAG MILL OPERATION EXAMPLEPROCESS PLANT DESCRIPTIONSAG MILL DESIGN AND SPECIFICATIONOPERATING PROBLEMS SINCE COMMISSIONINGDESIGN CHANGES AND FUTURE OPERATING STRATEGIESThe design of large mills has become increasingly more complicated as the size has increased and there is little doubt that without sophisticated design procedures such as the use of the Finite Element method the required factors of safety would make large mills prohibitively expensive the past the design of small mills, up to +/- 2,5 metres diameter, was carried out using empirical formulae with relatively large factors of safety. As the diameter and length of mills increased several crit.

Mill (grinding) Wikipedia

SAG is an acronym for Semi-Autogenous Grinding. SAG mills are autogenous mills but use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42" (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
