What is the transition period

The conveyor belt section between the head and tail rollers of the conveyor and the set of supporting rollers is called the transition section. In the transition section, the conveyor belt changes from groove shape to parallel or from parallel to groove shape, and the edge of the conveyor belt is stretched to generate additional tensile stress. The smaller the length of the transition section, the greater the additional tensile stress, which will cause the edges of the conveyor belt and the side rollers to cause wear and tear. As a result, the conveyor belt will fatigue prematurely, and even cause the edge of the conveyor belt to break. In order to ensure that the partial elongation of the edge of the conveyor belt does not exceed the elongation of the conveyor belt, the length of the transition section should not be too small. For the fiber core conveyor belt, the transition section length is taken as 1.3 times the distance between the rollers; because the allowable elongation rate of the steel cord conveyor belt is 0.2%, the transition section length is calculated according to the formula l≥2.67cc b, where b is the bandwidth , M; d is the groove angle of the idler, rad. If the value of l is much larger than the distance between the supporting rollers, several transition roller groups should be installed between the roller and the group of supporting rollers to prevent the belt from sagging and sprinkling.
