Abstract

An example arrangement on a crushing roller of a crusher may be configured to receive a crusher tooth that is used to generate a crushing action. The crusher tooth may project at least partially out of a surface of the crushing roller. In some examples, the crushing roller may include a receiving pocket that receives a tooth root of the crusher tooth. Moreover, at least one bracing means may be disposed in the receiving pocket substantially or completely recessed beneath the surface of the crushing roller. The bracing means may help brace the tooth root in the receiving pocket. In some cases, a fastener may be used to secure the bracing means in the receiving pocket.

First claim

1 .- 10 . (canceled)

11 . An arrangement for receiving a crusher tooth on a crushing roller of a crusher, wherein the crusher tooth is used to generate a crushing action and projects at least partially out of a surface of the crushing roller, the arrangement comprising:
a receiving pocket incorporated in the crushing roller, wherein the receiving pocket receives a tooth root of the crusher tooth that extends into the receiving pocket; and a bracing means disposed in the receiving pocket so as to be substantially or completely recessed relative to the surface of the crushing roller, wherein the bracing means braces the tooth root in the receiving pocket.

12 . The arrangement of claim 11 wherein the tooth root and the bracing means are incorporated in the receiving pocket adjacent to one another.

13 . The arrangement of claim 11 wherein the receiving pocket comprises a pocket wall, wherein the bracing means braces the tooth root against the pocket wall.

14 . The arrangement of claim 11 wherein the bracing means is form fit to the tooth root.

15 . The arrangement of claim 11 wherein the crushing roller rotates in a rotation direction, wherein the bracing means is disposed behind the crusher tooth in the receiving pocket relative to the rotation direction of the crushing roller.

16 . The arrangement of claim 11 wherein the bracing means comprises a bracing wedge that braces against the tooth root by at least one screw-action member.

17 . The arrangement of claim 16 wherein a base of the receiving pocket comprises a threaded bore in which the screw-action member is screwed to draw the bracing wedge into the receiving pocket towards the base of the receiving pocket.

18 . The arrangement of claim 16 wherein the bracing wedge is braced away from a base of the receiving pocket by the screw-action member so as to generate a clamping action of the bracing wedge with the tooth root in the receiving pocket.

19 . The arrangement of claim 11 wherein the bracing means comprises a wedging lock that has a rotary member and two pressure-exerting jaws, wherein the two pressure-exerting jaws are forced apart from one another by rotation of the rotary member so as to generate a clamping action of the tooth root in the receiving pocket.

20 . The arrangement of claim 19 wherein the rotary member comprises a tool mount for engagement with a turning tool for manually and/or robotically adjusting the wedging lock between a closed position and an open position.

21 . A crushing roller for a crusher, the crushing roller comprising:
a crusher tooth for comminuting material, the crusher tooth protruding from a surface of the crushing roller; a receiving pocket disposed in the crushing roller, wherein the receiving pocket receives a tooth root of the crusher tooth; and a bracing means disposed in the receiving pocket so as to be substantially or completely recessed relative to the surface of the crushing roller, the bracing means for securing the tooth root in the receiving pocket.

22 . The crushing roller of claim 21 wherein the receiving pocket is a milled receiving pocket.

23 . The crushing roller of claim 21 further comprising at least one optical or radio-technology system for detecting a position of at least one of the crusher teeth or the bracing means configured as a wedging lock.

24 . The crushing roller of claim 21 further comprising a fastener for securing the bracing means in the receiving pocket.

25 . The crushing roller of claim 24 further comprising a cover secured above the receiving pocket for protecting at least one of the bracing means or the fastener.
