Abstract
A gyratory crusher includes a frame, a bonnet, a gyratory crusher head, supported by the frame and being spaced relative to the bonnet such that a crushing chamber is formed therebetween, and a hydraulic channel formed integrally within the frame. First and second hydraulic cylinders are attached to the frame and support the bonnet on the frame, and the first and second hydraulic cylinders are connected to the hydraulic channel so as to be in hydraulic communication therewith. First and second hydraulic accumulators are supported by the frame and are in hydraulic communication with the hydraulic channel and the hydraulic cylinders. The hydraulic accumulators and the hydraulic channel are arranged to allow uncrushable material to automatically pass through the crushing chamber.
