ABSTRACT:
A feeder distributor is mounted above an annular crushing chamber of a gyratory crusher and operates to distribute feed uniformly around the entire circumference rather than at one revolving point. A rotating cylinder has a rotating bottom plate of larger diameter connected to it by ribs leaving a circumferential opening between the cylinder and the plate. The circumferential opening is sized to prevent the flow of material when the cylinder and plate are not rotating. When rotating, the material is thrown off of the plate around the entire circumference of the plate by centrifugal force. This provides good continuous distribution of material around the entire crusher chamber regardless of the feed rate into the cylinder.
