General conveyor belt: overlay: tensile strength of not less than 15Mpa, ultimate elongation of not less than 350%, the amount of wear ≤200mm3, longitudinal sample interlayer adhesion strength between the fabric layers is not less than the average of 3.2N / mm, covered with plastic and between the fabric layer is not less than 2.1 N / mm full-thickness longitudinal elongation at break of not less than 10%, with reference to the whole thickness of the longitudinal force the elongation is not more than 1.5% Nylon (NN), polyester (EP) conveyor belt: cover layer : tensile strength of not less than 15Mpa, ultimate elongation of not less than 350%, the amount of wear ≤200mm3 layer between the adhesive strength between the longitudinal sample fabric layer is not less than the average of 4.5N / mm Guiyang conveyor belt manufacturers, plastic cover with a cloth layer between not less than 3.2 N / mm full-thickness longitudinal elongation at break of not less than 10% of the conveyor belt manufacturer, the whole thickness of the vertical reference force elongation of not more than 4%. The second method is to install the self-aligning roller group, self-aligning roller group has a variety of types such as the intermediate shaft type, four-link, vertical roller conveyor manufacturers such as Kunming, the principle is the use of block or roller in a horizontal plane in the direction of rotation of the transverse thrust block or automatically adjust the belt Shiyan conveyor belt deviation manufacturers aim to reach the heart, which the forces and carrying idlers skewed by the same force of circumstances. Usually in the total length of the short conveyor belt conveyor using this method is more reasonable two-way run-time or because of the shorter belt conveyor easier deviation and not easy to adjust. And long belt conveyor is best not use this method, because the use of the life of the belt would aligning roller group have some impact.
