Abstract

The extruder uses one motor to rotate only two bladed rotor shafts, viz. a main shaft (1) and an auxiliary shaft (2), both fitted with a row of blades providing a mixing and kneading zone, and worms forming a pre-compression zone followed by a vacuum chamber. Only shaft extends beyond the vacuum chamber and ends in another worm causing final extrusion of the mixt. Both shafts are pref. in the same horizontal or slightly sloping plane. Simple construction and maintenance are provided.
