Abstract
The present disclosure concerns a belt conveyor roller wear liner superposable against an outer peripheral surface of a roller cylindrical body, the roller wear liner comprising: a shock-absorbing matrix; and a plurality of inserts, spaced-apart from one another and embedded in the shock-absorbing matrix with external surfaces of the inserts and the shock-absorbing matrix, extending between the inserts, being exposed outwardly, the roller wear liner being substantially ring-shaped. It also concerns a corresponding belt conveyor roller assembly, a corresponding belt conveyor and a corresponding method.
Claims20
A belt conveyor roller wear liner superposable against an outer peripheral surface of a belt conveyor roller cylindrical body, the roller wear liner comprising:
- a shock-absorbing matrix having a belt-facing face;
- and
- a plurality of inserts embedded in the shock-absorbing matrix and spaced-apart from one another, at least one of said plurality of inserts comprising:
- a belt-contacting face;
- an opposed inner face;
- wherein the belt-contacting face of said at least one of said plurality of inserts and the belt-facing face of the shock-absorbing matrix define together a substantially continuous belt-contacting surface of the roller wear liner;
- and
- wherein said at least one of said plurality of inserts has a perimeter and comprises a peripheral wall extending between the belt-contacting face and the inner face, a retention groove being formed in the peripheral wall and extending along at least a portion of the perimeter.
A belt conveyor roller wear liner superposable against an outer peripheral surface of a roller cylindrical body, the roller wear liner comprising:
- a shock-absorbing matrix having a belt-facing face;
- and
- a plurality of inserts, spaced-apart from one another and embedded in the shock-absorbing matrix, each of the plurality of inserts having a belt-contacting face;
- wherein the belt-contacting faces of the plurality of inserts and the belt-facing face of the shock-absorbing matrix form together a substantially continuous belt-contacting surface of the roller wear liner;
- and
- wherein the roller wear liner is substantially ring-shaped and extends partially along less than about 50% of a length of the roller cylindrical body when superposed against the outer peripheral surface of the roller cylindrical body.
A method for manufacturing a belt conveyor roller wear liner, comprising:
- providing a wear liner mat and a plurality of inserts, each of the plurality of inserts comprising a belt-contacting face and an opposed inner face;
- securing the inner faces of the plurality of inserts to the wear liner mat, the plurality of inserts being spaced apart from each other;
- placing the wear liner mat with the plurality of inserts secured thereto in a mold;
- and
- injecting a shock-absorbing material in the mold to form the roller wear liner comprising a shock-absorbing matrix embedding the plurality of spaced-apart inserts;
- wherein the belt-contacting faces of the plurality of inserts are exposed outwardly when the roller wear liner is removed from the mold.
