Novel system for providing a homogeneous mixture of materials comprising an internal mixer, an extruder, a cavity transfer mixer, means for discharging a mix from the internal mixer directly into the extruder, said extruder and cavity transfer mixer being juxtaposed in fluid-tight arrangement whereby material traversing the length of the extruder passes directly into the cavity transfer mixer, means for injecting material into the cavity transfer mixer for admixture with material traversing therethrough from the extruder, output means for removing the resulting homogeneous mix from the cavity transfer mixer, and motor means for operating said internal mixer, extruder and cavity transfer mixer, said motor means comprising means for separately driving and varying the speed of said cavity transfer mixer, whereby said cavity transfer mixer is adapted for operation at varying speeds higher than said extruder.
