Abstract

Apparatus for blending bulk particulate solids comprises a distribution chute bin, a cone section having outer and inner cones, and a flow pattern controller outlet device. The solids may be recirculated from the outlet device to the chute bin for additional blending. The chute bin prevents particle size segregation by causing mixing of coarse and fine particles. The inner cone permits mass flow adjacent the outer cone, and also enforces the flow velocity profile imposed at the bottom of the cones to continue to the top of the inner cone. The flow pattern controller is operable to shift between a blending mode resulting from the difference in the velocity profiles within and around the inner cone and a uniform flow mode useful when emptying the apparatus.
