Mode Of Operation Of Sag And Ball Mills

or SAG mill. Development of ever larger SAG units has helped in the processing of lower grade ores and the simplification of the crushing section - elimination of secondary and tertiary crushing and of the milling section - in terms of the numbers of ball and rod mills used previously. Principle of Operation The mill operates as a wet .
