Crushing shell

Abstract

The invention relates to a crushing jacket (20) of a cone and / or gyratory crusher for mounting inside a crusher upper part (30), wherein the crushing jacket (20) has a central longitudinal axis (M) extending in the longitudinal direction of the jacket, wherein the crushing jacket (20) has a material feed (24.1) on its upper side (O) and a material discharge area (24.2) on its opposite lower side (U), and wherein the crushing jacket (20) has a base part (21) with an outer clamping surface (28).To reduce the number of parts and the assembly effort, the invention provides that the base part (21) has a support section (25) with radially outwardly projecting fastening projections (26), wherein the fastening projections (26) are spaced apart from each other in the circumferential direction of the support section (25) by means of spacing areas, wherein at least one clearance is provided in each of the spacing areas, which allows passage in the direction of the central longitudinal axis (M) from the underside (U) towards the top side (O) and wherein the radial extent of the clamping surface (28) outwards is at least partially greater than the radial extent of the fastening projections (26) outwards.
