Dual-Column Non-Stop Screen Changer
The dual-column, dual-channel design enables one screen to operate while the other is replaced without halting production. This ensures continuous manufacturing processes, prevents material interruptions and speed reductions caused by screen changes, and enhances overall production efficiency.
The dual-column, dual-flow-channel design enables simultaneous operation and replacement of screens without production stoppage. This ensures continuous production, prevents material interruptions and speed reductions caused by screen changes, and boosts production efficiency.
During screen changes, the backup screen remains operational while the hydraulic system precisely controls column movement. Material flow pressure fluctuations are minimized to within ±5%, guaranteeing stable extrusion processes.
The large filter surface area delivers high filtration efficiency, effectively removing impurities and particles from plastics or rubber to guarantee product quality. Simultaneously, the expanded filtration area accommodates greater impurity loads, extending individual filtration cycles and reducing screen change frequency.
The main body of the dual-column screen changer is typically constructed from high-quality alloy steel treated with nitriding. This ensures a robust structure with strong load-bearing capacity, excellent wear and corrosion resistance, and extended service life.
The screen change process features high automation and user-friendly operation, reducing labor intensity for workers. Equipped with safety shielding, it effectively safeguards operator safety.
The dual-column screen changer is suitable for applications including chemical fiber production, blown film, cast film, and cast sheet manufacturing, as well as pipe, sheet, wire, and fiber production, pelletizing lines, and recycling. It meets the high-temperature, high-pressure, and high-extrusion demands of any polymer material and is compatible with extruders of various standards.
