In a copper ore mine in Choapa Province,Chile, pebble crusher plays an important role in the copper ore processing. After the trucks feed the raw copper ore into hopper, the primary jaw crusher will crush the raw copper ore and then the minerals will be transported by conveyor belt system into the SAG mills. In order to improve the SAG mill performance , pebble crusher can be installed before the SAG mills, The pebble crusher can raise the throughput and the positive effect is immediately obvious. The output and copper-in-concentrate increases despite a lower average ore grade of 0.88% Cu, mainly because of the pebble crusher added to the grinding circuit.

In a iron ore mine in Western Australia, This iron ore mining project features an open-pit magnetite mine and processing facility. KEFID cone crusher is used as pebble crusher in the crushing process. The iron ore is fed to the crusher and then is sized to 140 mm and conveyed to an coarse ore stockpile. The coarse iron ore which is smaller than 13mm is conveyed into the plant, so the SAG mills can reduce the iron ore size further more, these iron ore larger than 13mm will be sent to short head cone crusher as pebble crusher to be crushed again.
