Abstract

A wear element system, primarily for rock, stone and gravel handling equipment. includes a plurality of wear elements received in support rails. The support rails being fastened to surfaces of the equipment. Side edges of two adjacent wear elements are received in one of the support rails. The wear elements and support rails are shaped to fasten the wear elements in the support rails by means of wedge elements. The wedge elements are pushed down between the wear elements inside the support rails.

First claim

The invention claimed is:

1. A wear element system for equipment handling rocks, stones and gravel, comprising:
a plurality of wear elements received in support rails, wherein the support rails are configured to be fastened to surfaces of the equipment;
side edges of two adjacent wear elements received in one of the support rails, wherein the wear elements and support rails are formed to fasten the wear elements in the support rails; and
wedge elements pushed down between the wear elements inside the support rails to fasten the wear elements in the support rails.

2. The wear element system of claim 1 , wherein the wedge element and the wear elements have a close fit inside the support rail.

3. The wear element system of claim 1 , further comprising end parts are placed at opposite sides of a set of wear elements, wherein each end part is received in a support rail together with an adjacent wear element and wherein a wedge element is pushed down between the end part and the adjacent wear element inside the support rail.

4. The wear element system of claim 1 , wherein side edges of the wear elements have protruding parts placed below protruding parts of a groove of the support rails after mounting of the wear elements and wherein the side edges of two adjacent wear elements are placed inside the groove of each support rail.

5. The wear element system of claim 4 , wherein inclined sides at the side edges of the wear elements abut inclined outer sides of the support rails after mounting of the wear elements.

6. The wear element system of claim 4 , wherein the wear elements are made of an elastic material.

7. The wear element system of claim 1 , wherein the support rails have a central part and inclined sides projecting from opposite sides of the central part, the inclined sides being received in inclined slits of the wear elements.

8. The wear element system of claim 7 , wherein the inclined sides of all but one support rail incline in the same direction and wherein the inclined sides of one support rail inclines in opposite directions.

9. The wear element system of claim 7 , wherein the wear elements are made of a stiff material.

10. The wear element system of claim 1 , wherein each support rail has a central part and a number of inclined lugs projecting from opposite sides of the central part.

11. The wear element system of claim 10 , wherein a layer having a number of openings are placed on the support rails with the lugs of the support rails received in the openings of the layer.

12. The wear element system of claim 11 , wherein the layer is a silencer.

13. The wear element system of claim 1 , wherein each wear element has flanges at two opposite sides of the wear element and wherein each flange has a part projecting upwards and outwards from a lower edge of the flange.

14. The wear element system of claim 1 , wherein each wear element has a flat upper side, wherein a thickness of the wear element is bigger in a central part than at the side edges of each wear element and wherein the difference in thickness between the central part and the side edges of each wear element corresponds with a thickness of the central part of each support rail.

15. The wear element system of claim 1 , wherein the support rails are fastened to the equipment by fastening means selected from the group of adhesive tape, glue, welding or bolts.

16. The wear element system of claim 1 , wherein the equipment is selected from the group of a crusher, screen feeder, hopper or chute.
