Core Advantages of Dual-Piston Screen Changers in Plastic Pelletizing
Dual-piston screen changers enable non-stop screen changes through a dual-plunger, dual-flow-channel design, ensuring continuous production. Increased filtration area and a progressive material feed and venting structure enhance filtration efficiency and product quality. Wear-resistant materials and optimized flow channel design extend equipment lifespan while accommodating diverse requirements.
Non-Stop Screen Changing Ensures Continuous Production
The dual-plunger, dual-channel design allows both screens to operate simultaneously. When one screen requires replacement, the other continues functioning, enabling screen changes without production stoppage. This guarantees uninterrupted production while minimizing material waste.
High-Efficiency Filtration and Product Quality Assurance
Increased filtration area: Curved or large-area filter designs (e.g., dual-column four-station versions) significantly expand filtration area compared to traditional single-screen changers, effectively handling high-viscosity materials and fillers (e.g., glass fiber, calcium carbonate).
Product quality assurance: Progressive material feeding and venting structure prevents gas entrapment, ensuring uniform product consistency.
Enhanced Product Quality and Adaptability
Optimized Flow Channel Design: Minimizes material stagnation and degradation risks. The removable orifice plate structure facilitates cleaning of cold material.
Flexible Filtration Precision: Supports rapid switching between 20-300 mesh screens, accommodating diverse requirements from coarse impurity removal to optical-grade precision filtration.
