SAG mills and AG mills have different definitions and operate differently. SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore.
m length (190) single SAG mill equipped with a 20 MW electric motor. The SAG mill product flows to two m (120) by m (240) horizontal screens, whose combined oversize (pebbles) is diverted to two Metso MP 800 cone crushers. The crushed product returns to the SAG mill feed, closing the primary grinding circuit. The horizontal screen ...

The SAG/Ball Mill Circuit has an overall processing capacity of 2300 TPD. A ft x ft, 1500 HP fixed speed SAG Mill is fed with ore coming from four feeders.
Generally, filling the mill by balls must not exceed 30%35% of its volume. The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length. The optimum ratio between length L and diameter D, L: D, is usually accepted in the range
A SAG mill is a type of mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually to times the diameter of the shell. The SAG mill operates in a closed circuit with a screen. The product from the SAG mill is fed to a ball mill, which operates in a closed circuit with a cyclone.
Working Principle of a SAG Mill. The rock and grinding media are placed in the mill and rotated, causing the grinding media to tumble and crush the rock into smaller pieces. The mill operates in a closed circuit with screens that size the ore and send it back to the mill for further grinding. The product from the mill is then sent to a cyclone ...
