Melt pump and screen changer

Performance characteristics

1. The double-column four-station screen changer is designed as a four-channel filter structure, and the four filter work at the same time, without interrupting the material flow, without interrupting the products, and realizing the non-stop screen change.

2. The design has the exhaust function of primer, which can prevent the influence of gas generated in the process of changing the screen on the downstream products.

3. The four-channel design greatly increases the filter area of the material and reduces the frequency of changing the screen, which is especially suitable for the application of recycled materials.

4. Reasonable structure design, simple operation, ideal effect, suitable for high capacity, high efficiency, large-scale extrusion equipment continuous operation.

Scope of application

Mainly used in chemical fiber, blown film, flat film, casting film, pipe, plate, wire, fiber manufacturing, pelleting and recycling granulation conditions.
