Continuous screen changer with Backflush System
The continuous melt filtration screen changer will automatically control the servo motor to automatically rotate, exhaust, and feed. Continuous production is possible without turning off the machine to change the screen, thus avoiding down time, and improves the production efficiency. The continuous melt filter is often used in film blowing machines, wire drawing machines, tube extruders, and other plastic extrusion equipment.
In the plastic granulation and extrusion industry, melt filters are a large part of a continuous rotary extrusion system, and are also key to determining the quality of granule products. Leeny’s melt filters can be installed into a broad range of extrusion systems, such as plastic granulators, aluminum plastic plate extruders, XPS extruders, film faced plywood extruding machines and more.
Suitable plasticsThe continuous melt filtration screen changer is suitable for PP, PE, PS, PA, PVC, PC, PET and other plastics.
