Screen changer is an essential equipment in the production of PE and PP recycled plastics

The screen changer is a manual or automatic switching device including one or more screens for filtering out foreign particles and contaminants when plasticizing the material flow screen. The filter mesh is supported by an alloy porous plate that is mounted on a plate or column carrier that can be moved to switch between a system working position and an off-line non-working position. The screen changer can be installed on any new or existing extruder, melt pump, reactor or other extrusion line. It can be used to filter any type of polymer, rubber or ceramic melt.

In the plastic extrusion production, there may be various impurities and foreign materials in the raw material and fine crystal particles with incomplete plasticization. In particular, there are paper scraps, aluminum foil, sand, iron filings, copper wire, sawdust, etc. during the recycling of recycled plastics. Failure of defoamers and other impurities, the presence of these impurities if no screen changer for impurity filtration, will cause the decline in product quality, increase the number of defective products and production interruption, and even damage the extrusion equipment to As for the huge waste of raw materials, the production cost and energy consumption are high, the production capacity is relatively reduced, and the labor intensity of workers is increased.
