Abstract

Es wird ein Mischer zum kontinuierlichen Mischen, Einfärben und Homogenisieren von viskosen Stoffen beschrieben, welcher nach dem Prinzip einer Vielwellenschnecke mit vorzugsweise zweigängigem Dichtprofil arbeitet und dessen Wellenkränze mit verschiedenen Fördergeschwindigkeiten arbeiten, so daß die Maschine mit verschiedenen Teilmengen dosiert beaufschlagt werden kann, deren Summe der Wellenanzahl entspricht und deshalb eine überlagerte Längsmischung Farb- und/oder Schwankungen einzelner Mischungskomponenten im Verarbeitungsgut auszugleichen in der Lage ist. Außerdem wird ein Verteilergetriebe für derartige Mischer beschrieben.
