Continuous Screen Changer with Four Plates Circulation

This series of screen changer consists of four independent breaker plates, each with openings of same diameter and screen pattern. The rotation of these specially treated alloy metal plates gives superior sealing ability and durability. This type of screen changer has slight flow fluctuation during screen changing. It can  guarantee a continuous and stable extrusion production.

Breaker plates move in the same direction one by one, improved filtration performance, convenient to clean.

Equipped with preheating and ventilation design to minimize the effect of possible temperature, pressure, melt flow fluctuation on polymer during screen changing process.

No rupture on film and filament production and changing the screen without stopping the production.

It can be used for pelletizing, pipe, plate, sheet, EPE, EPS, , XPS extruded plate, PVB film, board, squeeze net, BOPET / BOPP, filament.
Years of practical applications show that the significantly effect of PE, PP, drawing, EPE, EPS production, improved products can meet the drawing and spinning of PET and other polyester products.
