Abstract: The method and apparatus of the invention are for collecting particulate material which falls off the underside of the lower return run of a belt conveyor, and returning that material to the carrying run of the conveyor. An elevator is mounted around the conveyor at the position of a support roller for the lower run, where there is vibration and material is dislodged. The dislodged material is conveyed to a chute over the upper rim of the conveyor without any scraping contact with the underside of the lower run.
