The hopper belt conveyor is usually used to transferred the cut fish from the hopper to the meat separator. Generally, eyelink conveyor belts are driven directly on the eyelinks by means of specially developed drive chain sprockets. The chain sprockets will be placed in combination with a roller. In all applications with chains a negative bend of the belt can easily be achieved by means of chain sprockets or wear strips of the hollow pin roller chain. For a moderate length and belt load, drive sprockets with a minimum of 8 teeth are used.
