A mixer or compounder with an elongate barrel (14) having a processing chamber of the configuration of two or more intersecting cylinders (13a,13b) receives material at one end and discharges it at the other. Parallel co-rotating mixer shafts (17,18) extend axially in the chamber and have co-wiping, angularly oriented, mixing members on each shaft, which also wipe the chamber walls. Multiple rotary hydraulic motors (M1,M2), driven synchronously in parallel by the same hydraulic pump system, drive intermediate shafts (48,49) parallel with the barrel shafts, and a gear driving each mixer shaft is driven by gear mechanisms on the intermediate shafts so that each mixer shaft is driven in the same direction of rotation by both hydraulic motors and imparts an increased equal torque to the mixer shafts. |
