<p>Apparatus for treating powdery rubber mixtures to form processed intermediate products comprises volumetric metering means; a filling extruder; a mixing and plasticizing portion located at the downstream end of the filling extruder and having a central toothed spindle, toothed planetary spindles and an internally toothed housing; and forming out means shown as an extruder cascade connected to the mixing and plasticizing portion and extruding material through a perforated plate with cutting blades. The mixing and plasticizing portion is of only short length and can effect intensive working but does so for only a short period of time on the material passing therethrough so that the material is not damaged by being over-heated.</p> |
