Double-column screen changer

Screen changer is commonly used in the following production lines (1), from plastic resin synthesis reaction device to bulk particle extrusion granulation production line.

(2) Ceramic extrusion production line.

(3) Polymer (plastic, rubber) molding production lines, including film blowing, casting, sheet, pipe, profile, plastic recycling, granulation, wire drawing, underwater granulation, masterbatch granulation and extrusion coating production lines.

(4) Suitable for various granulators, extruders, film blowers, wire drawing machines, sheet extruders and tube extruders.
