Definitions
- FIGS. 4 to l 1 are high-lighted by FIGS. 4 to l 1 as follows:
- a continuous internal mixer comprising a barrel forming two laterally interconnecting substantially cylindrical and mutually parallel chambers having interspaced charging and discharging ends, means for moving material through said chambers, said barrel having a top opening above the interjoining portions of said chambers, rotors extending through said chambers and having blades with cross sections substantially like that of a Banbury-type blade and having at least portions below said opening, and means for rotating said rotors so their blades move downwardly towards each other below the upper junctions of said chambers, said blades being constructed to impart mixing energy to material under radial pressure while this material moves through said chambers under said opening, the latter having a maximum transverse width extending transversely between vertical planes extending through the axes of said two rotors.
