Introduction to the Composition and Structure of the Double Cylinder Hydraulic Screen Changer for Plastic Extruder

The double cylinder screen changer for plastic extruder consists of a main body and two core shafts, each symmetrically equipped with one or more filtering channels. The filtering channels on these two core shafts can be in the working position at the same time, and also allow the filtering channels on one core shaft to be in the working position, while the filtering channels on the other core shaft are in the non working position, to achieve non-stop screen changing.
