Abstract
A hammer bar for use in a rotor of a crusher comprises a body, which is adapted to be mounted in the rotor to extend parallel to the axis of the rotos, and tools, which are detachably mounted on the body and comprise each at least one retaining rail extending in a longitudinally extending retaining groove formed in the body. To facilitate the insertion and removal of the tools, the body consists of two parts, which define between them a joint extending along and adjoining said retaining groove, and clamping means are provided for clamping said body parts against each other at said joint.
Claims6
A hammer bar for use in a rotor of a crusher, the rotor having a drive shaft extending in an axial direction, and the hammer bar comprising
- (a) an elongated body extending in the axial direction and defining a retaining groove extending in said direction, the elongated body consisting of
- (1) two body parts defining therebetween a joint extending along the retaining groove in said direction, the joint dividing the elongated body into said two body parts,
- (b) supporting members engaging outer surfaces of the body parts,
- (c) a supporting plate extending in the axial direction between the supporting members and radially inwardly of the outer body part surfaces,
- (d) a plurality of tools juxtaposed in said direction along said retaining groove, each of said tools comprising
- (1) a retaining rail engaging said retaining groove, and
- (e) clamping means comprising drive means arranged between the supporting plate and supporting members for pressing the outer surfaces of the body parts against the supporting members and the body parts against each other at said joint whereby the two body parts are wedged between the supporting members.
