  • Two-shaft continuous mixing apparatus
    Patent number: 5143448
    Abstract: A two-shaft continuous mixing apparatus includes a housing containing two rotors having substantially horizontally aligned centerlines and a material passage formed so as to communicate with a mixing chamber in which the rotors rotate, the material passage extending nearly horizontally from a discharge port of the mixing chamber. The material passage has an upper surface forming an edge with the mixing chamber, and a lower surface forming an edge with the mixing chamber. The material is thereby scraped off the edges and flows through the material passage as the rotors are rotated.
