conveyor belt for mining

conveyor belt for mining 1.Tensile strength: 6Mpa to 24Mpa. 2.Thickness: 5mm to 20mm conveyor belt for mining Specifications

Cotton canvas is woven by cotton fibers both in warp and in weft, its elongation is relatively low, it is good in mechanical fastening and adhesion with rubber, which has relatively little deformation under high temperature, suitable for short-distance and light-load transportation.Polyester cotton conveyor belt is the upgraded product of cotton conveyor belt. And its resistant tension body is woven by polyester cotton fibers in warp and cotton fibers in weft. Its comprehensive physical and mechanical characteristics are obviously better than those of cotton conveyor belt, especially the belt body is thinner and lighter, the belt has better anti-shock. This the belt has better use function can reduce energy and material consumption for users. It is suitable for medium, short-distance and moderate-load transportation of materials.
