ABSTRACT:
The continuous mixing apparatus for preparing a rubber composition has a mixing chamber accommodating at least one rotor rotating in a stator and extending between an upstream end and a downstream end between which the material progressively passes. The base elastomers are introduced at the upstream end of the mixing chamber by means of volumetric pumps capable of delivering the said base polymers under pressure. It has members for the dosaging and forced introduction of the other components, arranged along the mixing chamber at at least two longitudinally separated positions between the upstream end and the downstream end.
