Plastic Extrusion Filter-Double Plate Type Continuous Screen Changer
PRODUCT DESCRIPTION
A continuous screen changer is a machine that filters out impurities in the polymer extrusion process—without interrupting the process when a dirty screen needs to be changed. It's used in melt filtration processes where debris can clog up screens in a very short time and process disruptions are costly.
