Abstract

The invention relates to a turbo-mixer extruder machine of the type comprising a rotating screw 1 having helicoidal flights, which screw is housed in a fixed barrel 2 forming the extrusion chamber. According to the invention, a set of directing discs 3, comprising blades whose hydrodynamic profile and angle of attack are adapted to the viscosity of the processed compound, are fixed inside the barrel, the flights of the screw taking the place of the blades in the regions of the discs. Application to extrusion with mixing and homogenising effect.
