Abstract
A conveyor system for solid bulk materials such as cement, alumina, and rock which combines the principles of a fluidizing gravity conveyor and a vibratory conveyor wherein the air supplied to the plenum chamber of the conveyor is rapidly and continuously pulsed in an on-off manner. The apparatus may take the form of a conveyor section with a pair of plenum chambers and the fluidizing gas alternately supplied to the two plenum chambers, or the invention may be used in a storage and material discharge vessel wherein a pair of conventional fluidizing gravity conveyors are employed along the length of the vessel with the pulsing taking place by alternating the supply of gas between the two conveyors.
