Abstract

A wear-resistant lining element ( 1 ) for a surface subjected to wear has an outwardly directed surface ( 4 ) over which material in the form of pieces or particles, such as crushed ore and crushed rock material, is intended to move. The wear-resistant lining element also has a thickness (d). The wear-resistant lining element ( 1 ) comprises elastomeric material ( 2 ) mainly adapted to absorb impact energy and wear-resistant members ( 3 ) mainly adapted to resist wear. The wear-resistant members ( 3 ) are in a plane (P) perpendicular to the outwardly directed surface ( 4 ) designed so that in the direction of thickness (d) they at least partially overlap each other. Moreover, a wear-resistant lining made of a number of wear-resistant lining elements ( 1 ) is disclosed.

Claims (12)

1. A wear-resistant lining element which is intended for a surface subjected to wear and which has an outwardly directed surface, over which material in the form of pieces or particles, such as crushed ore and crushed rock material is intended to move, and which has a thickness, the wear-resistant lining element comprising:

elastomeric material mainly adapted to absorb impact energy; and

wear-resistant members mainly adapted to resist wear,

wherein the wear-resistant members in a plane perpendicular to the outwardly directed surface are designed so that in the direction of the thickness they at least partially overlap each other, have a bottle-like shape with a neck portion and a bottom portion, and are arranged alternately with the neck portion upwards and downwards, the bottom portion being wider than the neck portion.

2. A wear-resistant lining element as claimed in claim 1 , in which the wear-resistant members are made of a ceramic material.

3. A wear-resistant lining element as claimed in claim 1 , in which the wear-resistant members are arranged in rows in the outwardly directed surface.

4. A wear-resistant lining element as claimed in claim 1 , in which the outwardly directed surface mainly consists of the wear-resistant members.

5. A wear-resistant lining element as claimed in claim 1 , wherein each wear-resistant member has a wear surface forming a part of the outwardly directed surface constituting a wear surface of the wear-resistant lining element.

6. A wear-resistant lining element as claimed in claim 1 , wherein the wear-resistant members are embedded in the elastomeric material of the lining element.

7. A wear-resistant lining for a wall subjected to wear, over which material in the form of pieces or particles, such as crushed ore and crushed rock material is intended to move, which wear-resistant lining is made of a number of wear-resistant lining elements, the wear-resistant lining elements comprising:

elastomeric material mainly adapted to absorb impact energy; and

wear-resistant members mainly adapted to resist wear, wherein the wear-resistant members in a plane perpendicular to the outwardly directed surface are designed so that in the direction of the thickness they at least partially overlap each other and are aranged alternately with a first portion directed upwards and a second portion directed downwards and, respectively, the second portion directed upwards and the first portion directed downwards, said second portion being wider than said first portion.
