This GP330 offers installed power up to 315 kW, with a cavity feed opening of 238 mm which is able to accommodate feed sizes produced by the primary crusher. “With variable eccentric stroke the unit can be optimised to suit several types of processes. The cone crusher chamber can be configured to operate from a secondary position in the plant all the way to a final stage quaternary crusher,” explains Marais. All operation data of the cone crusher is logged continuously and can be accessed by the standard on board Metrics monitoring system.
