MEI Blog: Where are SAG mills going? - Barry A WillsTurbo Pulp Lifter (TPLTM) - An Efficient Discharger to

Aug 25, &#; In our recent conversation, Prof Alban Lynch was very sceptical about where semi-autogenous grinding (SAG) mills have gone, and thinks they have taken us along the wrong track He feels that they may be attractive in terms of high productivity, but says that "their energy efficiency is poor, and I feel that these immense machines are going to turn into very large ball mills"pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of the SAG/AG grinding mills The general arrangement of AG/SAG mills discharge system is shown in Figure 1 BREAKAGE DISCHARGE Figure 1: Schematic of a typical sag mill operation.

Simplifying wet grinding with Metso AG/SAG mills AG/SAG mills are often the optimum solution for wet grinding (achieved in a slurry 50 to 80 percent solids) AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening, a rod mill, and some or all of the work done by a ball millThe high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores feasible Future circuits may see increasing use of high pressure grinding rolls (Rosas et al, ).
