  • Tips For Addressing Load Point Challenges And Increasing

    oct 12, 2018 transition distance is the length of conveyor belt used to transform from a flat shape exiting the pulley to the trough shape used to carry material. often transition distances are compromised to save space, but this can cause many problems, including premature conveyor belt wear, premature pulley lagging wear, conveyor roller failure, and transferring from power to gravity sections. when transferring a package from a power conveyor to a gravity curve, a straight section of gravity conveyor at least as long as the longest package to be conveyed should precede the curve. this is recommended because the force of the belt may be greater than the force of the curve, resulting in the package overshooting the curve.

    the transition distance is the length of the section between head or tail pulley and the first troughing idler. In some cases, intermediate idlers are placed along the transition distance to favour the passage of the belt from the flat to the trough shape.the transition roller is installed between the roller and the first set of standard rollers, so that the conveyor belt will gradually become grooved or flattened out of the groove shape, reducing the additional stress caused by the groove on the edge of the conveyor belt, and also preventing the conveyor belt from being flattened.
