ABSTRACT:
Bulk materials are supplied on to a conveyor one after another with the supply port filled with the material. Since the pressure applied to the conveyor surface by the material is constant, what is called the fall error is eliminated. In one embodiment the conveyor is moved while in another embodiment the material is carried by scrapers secured to a chain conveyor.
