In a standard cone crusher, the main shaft is housed in a frame attached to a mantle. A pinion / counter shaft assembly drives a bevel gear that rotates the cone. As material presses against the bowl liner by the mantle or cone, it is crushed into smaller pieces that fall through to the bottom.
The jaw crusher usually works in very severe conditions, that requires heavy load bearings. Generally, the speed and load of bearing are moderate, but, sometimes, the load spikes as uncrushable material passes through the chamber. In addition, due to the shaft deflection, jaw crusher also requests angle adjustability to compensate bearing seats misalignment and tilting.
