Hydraulic backflush automatic screen changer

The backflush screen changer is a continuous melt filtration device installed at the outlet of an extruder/melt pump. Its core feature is the addition of a reverse high-pressure flushing function to the non-stop screen changing process. This enables online removal of impurities from the filter screen, significantly extending its service life. It is particularly suitable for processing recycled plastics with high impurity content. Core Structure and Principle Typical Structure: Commonly features

Double-Plate Screen Changer for ∅350mm Pelletizing Extruders

For large-scale pelletizing extruders with a diameter of 350mm (commonly used for modifying, filling, and recycling pellets of materials such as PE/PP/ABS/PS, typically with an output of 10~30t/h), the double-plate screen changer serves as the mainstream continuous screen changing solution for this machine type. The dual-plate screen changer (dual-station plate type) is a continuous screen-changing device specifically designed for large-diameter, high-output extruders. Compared to single-plate a

Dual-Column Screen Changer for HDPE Ceramic Powder Pelletizing Production Line

The dual-column screen changer serves as a critical melt filtration device in HDPE ceramic powder pelletizing production lines. Its primary function is to filter impurities, undispersed ceramic powder agglomerates, and carbonized material from the melt. This ensures the purity and uniformity of the pelletized product while maintaining stable, continuous operation of the production line. Core Functions of the Dual-Column Screen Changer in This Production Line Impurity Filtration After HDPE and ce

Automatic Screen Changer for Wire Drawing Machines

I. High Degree of Automation Fully Automatic Operation: The automatic screen changer enables continuous, uninterrupted filter screen replacement without manual intervention, significantly reducing labor intensity and enhancing production efficiency. Intelligent Control: Through an advanced control system, the automatic screen changer initiates and terminates the screen-changing process based on preset pressure or time parameters, ensuring precise control. II. Stable Material Flow Fluctuation-Fre

Advantages of Plate Screen Changers and Their Application in Extrusion Production

Plate screen changers offer the following advantages: minimal impact on production and short flow paths. The short material path through the changer minimizes temperature and pressure fluctuations after passing through it. This significantly reduces disruption to the production process, ensuring stable and consistent product outputparticularly crucial for materials sensitive to temperature and pressure variations. Rapid screen changes can be completed in under 2 seconds, enabling quick changes w
