ABSTRACT:
Particulate materials are blended in a vessel which has a plurality of vertically extending conduits therein. The conduits are provided with a plurality of openings within the vessel, and terminate in a common collection zone. Certain of the openings are provided with baffle means to permit particles to enter the tubes when there is flow of particles through the tubes from higher elevations. The locations of the openings and the baffle sizes are selected such that the total flow of particles through the conduits at progressively lower elevations in the vessel increases substantially as a linear function with respect to vertical distance measured downwardly. An inverted cone can be employed in the bottom of the vessel to provide more uniform mixing of materials that do not flow through the conduits.
