Abstract
A wear and shock resistant multi-strata panel for lining a conveyor chute bearing aggregate, coal, and other bulk materials. The panel comprises a plurality of generally planar layers, and a plurality of panels may be used to line a chute. The layers are comprised of and sequentially arranged in a topmost ceramic layer, a corrosion-resistant first metallic layer, an elastomeric cushioning layer, and a bottom-most corrosion-resistant second metallic layer proximal to and in intimate contact with the chute support structure, or chute surface. The layers are consecutively bonded together to form a panel attached integrally to the chute structure.
Claims22
A chute liner for use in lining the impact surface of a bulk material conveyor chute comprising:
- a) a first layer, said first layer of ceramic material arranged for direct contact with the aggregate bulk material being moved through said chute;
- b) a second layer, said second layer of metallic material disposed directly underneath said first layer and arranged to couple closely with said first layer;
- c) a third layer, said third layer of elastomeric material disposed directly underneath said second layer and arranged to couple closely with said second layer;
- and
- d) a fourth layer, said fourth layer of metallic material disposed directly underneath said third layer and arranged to couple closely with said chute.
