The screen changer is a manual or automatic switching device that includes one or more screens for filtering foreign particles and impurities as the plasticized material flows through the filter. The filter is supported by an alloy perforated plate that is mounted on a plate or column carrier that can be moved to switch between a working position of the system and an offline inoperative position. The screen changer can be installed on any new or existing extruder, melt pump, reactor or other extrusion line. It can be used to filter any type of polymer, rubber or ceramic melt

We adopt the quick screen changer of hydraulic system ensure the continuously working of screen changing.Double position combined with special sealing structure guarantee stable operation of screen changer.

The hydraulic automatic screen changer switches the screen plate or the screen column back and forth by a complicated hydraulic station. The hydraulic automatic screen changer has the advantages of compact size, good back pressure sealing and quick change of mesh speed, and its deficiency is relatively easy to accept: high cost and complicated hydraulic structure.
