ABSTRACT:
A gyratory crusher with a tramp iron relief system having an annular manifold is disclosed. The gyratory crusher includes a frame, with the frame including a circumferential manifold ring having an internal hydraulic channel. A bonnet and a gyratory head are supported by the frame, with the gyratory head being spaced relative to the bonnet such that a crushing chamber is formed therebetween. The bonnet is adjustably mounted to the frame to permit relative vertical movement between the bonnet and the gyratory head. A hydraulic relief system is provided and includes at least one hydraulic cylinder operatively interconnecting the bonnet and the frame and being in flow communication with the hydraulic channel. The hydraulic relief system is arranged to allow uncrushable material to automatically pass through the crushing chamber.
