ABSTRACT:
A mixing device for mixing a first and second material together to create an output mixture. The device includes a first chamber containing the first material coupled to a mixing chamber defined between a rotor and a stator. The rotor is disposed inside the stator and rotates therein about an axis of rotation. The first chamber houses an internal pump configured to pump the first material from the first chamber into the mixing chamber. The pump may be configured to impart a circumferential velocity into the first material before it enters the mixing chamber. At least one of the rotor and stator have a plurality of through-holes through which the second material is provided to the mixing chamber. Optionally, a second chamber is coupled to the mixing chamber. The second chamber may house an internal pump configured to pump the output material from the mixing chamber into the second chamber.
