Abstract
Particulate blending apparatus including a vessel, the lower end of which is a downwardly tapered funnel-like section. A vertical divider divides the tapered section into first and second compartments. A vertical tubular member is centrally disposed in the vessel so that the lower end thereof provides an inlet into the vessel and the upper end opens into the upper portion of the vessel. First and second openings are provided on opposite sides of the vertical tubular member at the lower end thereof through which particulate materials may flow by gravity into the tubular member from the first and second compartments, respectively, of the tapered section. A blower may be connected to the lower end of the tubular member providing a stream of air therethrough by which particulate materials entering the tubular member through the first and second openings may be entrained therewith exiting through the upper end of the tubular member for redeposition in the vessel. Valve assembly may be provided by which the flow area of the first and second openings may be varied so that the mass flow of particulate materials from the first compartment may be substantially different than the mass flow of particulate materials from the second compartment.
