Cone Crushers. Cone crushers, similar to gyratory crushers, process smaller particle sizes. An eccentric shaft, driven by a gear and pinion, powers the main shaft's oscillation. This oscillation causes the cone head to move between open and closed discharge settings. Crushing happens through continuous compression between the liners.
