Hydraulic Screen Filter Changer

At Laizhou Yuening Machinery, we build hydraulic screen filter changers specifically for continuous plastic recycling and extrusion lines. These double-pillar hydraulic units are designed to eliminate downtime caused by clogged filters, letting you replace screens without stopping production. Built for heavy-duty use with materials like BOPP, PE, PP, EPS, ABS, and PS, they're made to handle the high temperatures and pressures of 24/7 granulator and extruder operation.

Unlike gear-driven models, these hydraulic changers use a double-pillar design for smooth, reliable operation. The system can be operated either hydraulically or manually, giving you flexibility on the shop floor. What really matters in daily use is that the line keeps running-no stops, no pressure drops, no lost production. The heavy-thickened, high-quality construction means these units hold up to the demands of continuous runs, with strong wear and high-pressure resistance. The high-precision filter design improves filter quality and increases the effective filtering area, which directly translates to cleaner melt and better-quality plastic pellets.

Key features that make these hydraulic changers practical for recycling lines include:

• Non-stop screen changing capability to eliminate production downtime
• Double-pillar structure with automatic adjustment seals for consistent sealing performance
• Oval-style filter design that doubles the filtering capacity for higher output
• Precision guide grooves that let filter plates install accurately without manual adjustment
• Compatibility with high polymer extrusion rates, supporting different production criteria

These hydraulic screen filter changers are most commonly used in plastic granulator lines, where they filter out impurities to ensure clean, uniform plastic pellets. They work with both hydraulic and gear mold heads, and are built to handle the high throughput of industrial-scale recycling operations. For many customers, these units have cut their screen-related downtime by hours each week.

Every unit is inspected before leaving our factory, with outgoing inspection video provided for your records. They come with a 1-year warranty on core components, including the engine and motor, so you can rely on them for continuous use in your workshop.
