Sealing ring for gyratory crusher

摘要

A gyratory crusher sealing ring assembly having an annular body (209) with a first part (200,201) to mate against a sealing surface (110) provided at an underside region of the crusher head (100) and a second part (202) for mounting the body at a support part (112,117) axially below the head. The sealing ring is configured not to flex or bend in response to the sliding contact between the ring and the head surface. This is achieved as the ring comprises a Young's modulus (E-modulus) in the range 1700 to 4300 MPa and is substantially rigid. The ring is biased against the sealing surface of the head via a bias component (204) or region.
