Here are some things to consider when making the choice between an HPGR-ball mill circuit and a SAG-ball mill circuit. ===Work index ratios === Having a hard ore is not a valid reason for choosing an HPGR circuit, the ore must be hard in a certain way. More specifically, it should have a rod mill work index greater than the ball mill work index, and a ball mill work i...") | ||||
