Plate Type Screen Changer

The Plate Type Screen Changer is a high-performance filtration device for plastic extrusion lines, utilizing a sliding plate (often hydraulically driven) that houses two or more breaker plates, each containing a filter screen pack. This design allows one screen to be in the melt flow path for filtration while the other is offline for replacement, enabling a continuous, non-stop production process, even during screen changes. It features robust, pressure-activated sealing to handle melt pressures up to 500 bar without leakage, is suitable for high-output applications and various polymers (like PP, PE, PVC), and often incorporates an air venting system to eliminate bubbles, ensuring consistent melt quality.
