Zur Lösung-der Aufgabe wird gemäß der Erfindung vorgeschlagen, die Drosselstelle eingangs des einen kleineren zylindrischen Durchmesser als der Misch- bzw» Knetteil aufweisenden Austragteiles des Spindelgehäuses vorzusehen und diese mittels auf den Arbeitsspindel vor den Austragsohneckengängen angeordneten, mit geringstmöglichem gegenseitigem Betriebsspiel nebeneinander laufenden, zylindrischen Drosselbunden mit verhältnismäßig großer axialer Länge durch gleichzeitiges axiales Verstellen beider Arbeitsspindeln gegenüber dem Spindelgehäuse zu steuern.To solve the problem, it is proposed according to the invention, the throttle point at the entrance of the having a smaller cylindrical diameter than the mixing or kneading part Provide discharge part of the spindle housing and this by means of the work spindle in front of the discharge son corner aisles arranged cylindrical throttle collars running next to one another with the lowest possible mutual operating clearance with a relatively large axial length due to simultaneous axial adjustment of both work spindles the spindle housing to control.
In Ausgestaltung der Erfindung wird ferner vorgeschlagen, das Spindelgehäuse in Strömungsrichtung der zu bearbeitenden Masse betrachtet vor der konischen Verjüngung durch eine Querfuge zu teilen.In an embodiment of the invention, it is also proposed that the spindle housing be machined in the direction of flow Mass viewed in front of the conical taper by a Split transverse joint.
Durch die Erfindung werden nicht nur die in der Aufgabenstellung angeführten Forderungen erfüllt, sondern mit der Erfindung wird gleichzeitig auch eine sehr feine Regulierung des Drosselwiderstandes erzielt, der nur abhängig ist von der jeweils eingestellten Länge des zylindrischen Drosselspaltes. Außerdem ergibt die verhältnismäßig große Länge der beiden Drosselbunde eine Gewähr für eine weitgehende Abdich-The invention not only meets the requirements set out in the task, but also with the Invention, a very fine regulation of the throttle resistance is achieved at the same time, which is only dependent on the set length of the cylindrical throttle gap. In addition, the relatively large length results in the both throttle collars a guarantee for extensive sealing
