Abstract
Abstract A wearing part for use in gyrated crushers. Either the mantle or bowl liner of a crusher are made of a composite in which a backing member with a high tensile strength supports a crushing or working surface having high wear resistance. The working surface is in the form of discontinuous surface members permanently mounted on or cast integrally with the backing body and structurally connected only by the backing body.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
99 words
In a wearing assembly for a crushing part of a crusher of the gyrated head type, a circumferential, generally continuous backing body of a material of predetermined hardness, formed and adapted to extend about and be removably supported against the crushing part, said body having permanently mounted thereon a plurality of discontinuous surface members of a material of greater hardness than the material of the body, said surface members being shaped and positioned to take substantially the entire crushing wear of the material crushed when the crusher is being operated, but being structurally connected only by the backing body.
Claim 2
Dependent Claim
99 words

Claim 3
Dependent Claim
23 words
The structure of claim 1 characterized in that the surface members constitute a series of segments extending about the axis of the crusher.
Claim 4
Dependent Claim
18 words
The structure of claim 1 characterized in that the surface members are physically interlocked with the backing body.
Claim 5
Dependent Claim
18 words
The structure of claim 1 characterized in that the surface members are individually bonded to the backing body.
Claim 6
Dependent Claim
18 words
The structure of claim 1 characterized in that the surface members are cast integrally with the backing body.
Claim 7
Dependent Claim
37 words
The structure of claim 1 characterized in that the backing body and the discontinuous surface members constitute a single continuous mass of metal with the surface members permanently joined to the backing but separated from each other.
