Screen Changer, also named melt filter is a device containing one or more screens through which plasticized material flows to remove impurities. The screens are supported by Breaker Plate, which is fitted on a carrier plate and can be moved from an operating on-line position to an off-line or non-operating position.

 

Screen Changer can be fitted to any new or existing extruder, melt pump, reactor or any extrusion line for compounding polymers, blown film, cast film, sheet, pipes, profiles, plastics recycling.

 

Different types of Screen Changers are available, to cater for different applications and process requirements. Manual type or slow speed screen changers require the production line to be stopped for a short time to enable the filter to be changed, other types, operating at high speed, can change filter without stopping or slowing down the extrusion process.

 

For the production of blow film, sheet, pipes, etc, continuous flow screen changers are the most suitable type as the melt continues to flow during a screen change.
