A gyratory crusher comprises an outer shell (4), which should be fastened in a frame (2) included in the crusher, and an inner shell, which is intended to be fastened on a crushing head and to define together with the outer shell (4) a crushing gap for receipt of material to be crushed. Upon fastening of the outer shell (4) a first abutment surface (34) on the outer periphery of the outer shell (4) is brought in a first step to abutment against a first contact surface (32) on the frame (2). In a second step a spacer member (28) is pressed in for clamping of the outer shell (4) between a second abutment surface (50) on the outer periphery of the outer shell (4) and the frame (2). A good abutment is provided both at the first abutment, surface (34) of the outer shell (4) and at the second abutment surface (50) thereof. |
