method for securing an outer shell to a rotary crusher, said outer shell itself, crusher having such an outer shell, and a spacing element for use in securing such an outer shell
"Method and device for attaching a crusher shell". The present invention relates to a rotary crusher comprising an outer shell (4) which must be fixed to a frame (2) disposed within the crusher, and an inner shell which must be fixed to a crushing head and defined together with the crusher. outer shell (4) a grinding space for receiving the material to be crushed. above the fixing of the outer shell (4), a first bearing surface (34) which lies on the outer periphery of the outer shell (4) is laid in a first step against a first contact surface (32). ) of the structure (2). In a second step, a spacing element (28) is compressed to enclose the outer shell (4) between a second bearing surface (50) disposed on the outer periphery of the outer shell (4) and the frame (2). ). satisfactory support is provided at the same time on both the first bearing surface (34) of the outer hull (4) and the second bearing surface (50) thereof.
