Weigh Belt Converyors, Continuous Weighing Conveyor Systems

A weigh belt conveyor is generally a slow speed conveyor installed with a single or two idler belt weigher. Weigh Belt Conveyors provide continuous weighing with better accuracy than a belt weigher. This is due to the generally slower belt speed. These weighers provide the advantage of requiring only minimal headroom and length.
