AMIT 135 Lesson 6 Grinding CircuitMining Mill Operator

AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill. Because of the range of mill sizes available AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. A diagram of types of AG/SAG mills
