Abstract
A pair of concentric tubes having an inlet and an outlet with the outer tube being closed at either end and the inner tube having a plurality of holes with compound angles designed to impart a swirling motion of the air admitted into the interior of the inner mixing tube. The holes are judiciously located around the inner tube for creating a swirling pattern. The inlet of the tubes leads the dry particles of two different compositions intended to be mixed into the mixer and the outlet leads the mixture to the next station utilizing the mixture. Air admitted internally of the outer tube feed the plurality of holes and the force of the air can be controlled to control the transport of the mixed particles.
