Abstract
A valve for controlling the flow of particulate solid material, especially a hot, friable, granular material. The valve comprises a fixed vertical feed tube and a concavo-convex valve member mounted for rotation about an axis forming an obtuse angle with the axis of the feed tube. The rotatable valve member is positioned so that its dished inner surface confronts the lower end of the feed tube and is essentially perpendicular thereto to block flow of material through the valve when it is in its closed position. The rotatable member has one or more openings therein that can be positioned in registry with the bottom of the feed tube to open the valve and permit the solid material to flow therethrough.
