It is a continuous conveying machinery with flexible conveyor belt as material carrying and traction component. An endless conveyor belt surrounds the driving roller and the redirecting roller. The upper and lower branches between the two rollers are supported by several rollers. The material is placed on the upper branch. The friction between the driving roller and the belt is used to drag the conveyor belt and the material to run. It is suitable for conveying bulk materials and finished items in horizontal and inclined directions. It can also be used in assembly lines for certain process operations. It has a simple structure, stable and reliable operation, strong adaptability to materials, large conveying capacity, low power consumption and wide application.
