2021-4-23  In primary-secondary HPGR circuits, the secondary circuit can be closed with a screen to provide a consistent top size and gradation for optimizing HPGR performance. Closed circuited secondary crushing can also bring benefits if cones are used in tertiary crushing, too. However, the cost of the additional equipment is not always welcome.

SHEDDING LIGHT ON SECONDARY CRUSHING B. Putland,

2014-10-1  Secondary crushing of the SAG mill feed, when implemented correctly, has been shown to significantly reduce SAG mill and total circuit specific energy. Very fine feed, good process control and or the presence of some coarse rock in the feed (partial secondary crushing) has been required to make a successful project. The reason secondary crushing works is relatively simple. The
