Abstract
A vertically oriented generally cylindrical vessel or hopper holds dry granular materials which are mixed together by applying repeated short bursts of pressurized air from nozzles in an air manifold which direct the air substantially parallel or slightly inward to the longitudinal axis of the hopper to repeatedly lift and drop the materials in the hopper to create a tumbling action. Adjustable throttling valve means are provided in the pressurized input to the manifold to control the air flow to and the pressure at the manifold.
