Double Piston Continuous Screen Changer for Plastic Extrusion Machine

Working principle of this GM-DP-E series continuous screen changer

As the polymer melt enters the main body ofthe screen changer, the melt stream is divided equally and flows into the two channels ,go through the two breaker plates, and the impurities are intercepted by the screen mesh, and when screen changing is required, one of the pistons with blocked screen pack is pushed out by hydraulic unit , and the other is still on the working position, we replace the fresh screen and then the piston with new screen is pushed into the working position, at this time, the air bleeding system also begin to work.  The other piston screen change is the same with above.  This type of continuous screen changer maintains a continuous melt flow.
