Abstract: A conveyor system for conveying materials includes an upper conveyor and a lower conveyor. The upper conveyor includes a first pulley, a second pulley spaced from the first pulley and first endless belt extending about the first and second pulleys. The lower conveyor includes a third pulley, a fourth pulley, a fifth pulley and a second endless belt supported about the third, fourth and fifth pulleys. The third, fourth and fifth pulleys support the second endless belt such that the second endless belt at least partially wraps about the second pulley of the upper conveyor against the first endless belt to sandwich materials therebetween and to elevate the materials from the lower conveyor to the upper conveyor.
