摘要：
A gyratory crusher outer crushing shell (200) and a crushing shell assembly. The crushing shell comprises a radially inward facing crushing surface (209) and a radially outward facing mount surface (225) provided with radially outward projecting contact regions (219,220) to contact the topshell (100) or an intermediate spacer ring (203). A ledge (213) or groove (1000) having an abutment face (300)is positioned at or axially above the upper contact region (219) to positionally support a sealing ring (214) for positioning between the crushing shell and the topshell or intermediate spacer ring.
