Abstract
A closed conveyor for transporting finely divided solids, such as grain and the like, comprising feed and discharge sections interconnected by a transport conduit and a return conduit. Sprockets are provided in the feed and discharge sections and a cable is trained about the sprockets and through the two conduits. The cable is equipped with material-engaging flights of area less than the cross-section of the conduit. Each sprocket is provided with material-engaging blades which serve to stir, fluidize and impart movement to the material being transported to render it as a fast-flowing dilute suspension. Lugs are provided on the cable between the flights and are positioned to be engaged by complemental lug-engaging elements on the sprockets. Each pair of lug-engaging elements on the sprockets fits between but in contact with a pair of lugs on the cable. The sprocket elements are notched to accept the cable lugs. By fitting between cable lugs, the sprocket elements restrain the cable from overrun and thus prevent direct contact between the cable and sprocket. Means are provided for driving the sprockets at high speed to fluidize and accelerate the material in the feed section. Altern…
