Screw-type extruding machine with discharge pump.

摘要

The invention relates to a mixing and processing device which is equipped with a separately drivable gear pump as the discharge means. …In order to avoid the deposition of material between the processing device and the discharge pump, a gear pump (5) overhung at one end face is flanged, by this end face, directly onto the discharge (41) of a screw extruder (4) in such a way that the infeed of a melt takes place directly into the suction chamber of the gear pump (5). As a result of this transfer without dead space, it is no longer necessary to carry out cleaning operations after standstill periods or when the material is changed. ……
