Abstract
Particulate materials are blended in a vessel provided with a plurality of vertically extending conduits therein. The vessel comprises a downwardly converging frustoconically shaped bottom wall which defines the lower region of the vessel. The conduits are provided with a plurality of longitudinally extending compartments having openings within the upper region of the vessel. The lower ends of the conduits and the compartments therein extend through the bottom wall, each communicating via a corresponding connecting conduit with a solids outlet at the open bottom of the bottom wall. At least one drain conduit communicates between a corresponding opening in the bottom wall and a corresponding compartment at a location below the bottom wall. A baffle is disposed within the vessel separating the upper and lower regions and comprises a downwardly converging inverted generally conical portion spaced above the bottom wall and defining therebetween a downwardly converging annular passage. Extensions of the compartments are contained within the connecting conduits. Various arrangements of positioning and spacing of drain conduits and corresponding openings in the bottom wall are disclosed t…
