Purpose:
The anti tearing fabric core conveyor belt is suitable for the fields of coal, mine, port, metallurgy, electric power, chemical industry, etc. it is also suitable for the places with high strength, long distance and large volume to transport sharp hard materials and high blanking height.
Structure:
The anti tearing fabric core conveyor belt is composed of upper covering layer, lower covering layer, polyester or nylon canvas layer, anti tearing layer and side glue.
Features:
The rubber surface of the conveyor belt on the polyester or nylon canvas core or the upper and lower cover rubber surface is added with a horizontally and evenly arranged anti tearing steel curtain or polyester wire mesh as the anti tearing layer, the anti tearing layer is perpendicular to the running direction of the conveyor belt, when the conveyor belt transports hard and sharp materials, the anti tearing layer can prevent the penetration of hard and sharp materials, once the penetration occurs, it can also produce enough resistance to hard and sharp materials Material tear resistance of the tape, so as to effectively prevent the occurrence of belt tear.
