As it turned out, designers are now adding secondary or pebble crushers to SAG circuits, on both greenfield and retrofit projects, to increase feed rate to the SAG mill. In other words, crushing plants, from primary to quaternary circuits, are here to stay. There are three main steps in designing a good crushing plant: process design, equipmentDESIGN OF THE AGNICO-EAGLE LARONDE DIVISION SAG MILL by John Starkey, Jean Robitaille, Paul Cousin, James Jordan and Glenn Kosick.

This depends on the mill diameter and the ball size. Feed size necessary to take 80% of the maximum piece of ore that will crushed by the balls. For the big SAG more than 8 meters optimal feed size will be - 50mm. Ball size - 120 ... 125mm. Do not a pebble crushing, the need secondary crushing. 2.
