BRF - Basic model for continuous melt filtration in modern plastics recycling

The BRF is the entry-level model for continuous filtration technology. Its effective melt flow combined with an optimized discharge system ensures high quality in processing all common polymers including LDPE, LLDPE, HDPE, PP, PS, ABS, etc. with low to high contamination levels. Thanks to their robust screens, the new continuous melt filters of the BRF series also make a major contribution to cutting operating costs in day-to-day production – especially when processing melts with mineral components.

Suitable for Compounding, Recycling,Extrusion 

Applications

The melt entering the filtration system is fed through rheologically optimized flow ducts onto a screen disk, and passes through the conical holes in the disk. Any contaminants are trapped on the disk, and are immediately removed by a rotating stripper and routed to the controlled discharge system.

Application areas

  • Packaging film
  • Bottle flakes
  • Food packaging
  • Detergent containers
  • Bags
  • Pipes
  • Batteries
  • Vehicle bumpers
  • Base plates
  • Agricultural sheeting

Advantages

  • Robust screens for longer life
  • Also suitable for mineral contaminants
  • Controlled dirt discharge in a safe process environment
  • Flexible application options based on different screen fineness grades
  • Innovative control unit for user-friendly operation

High performance Melt Filters – The ECO Series

The continuous melt filters in the ERF series are suitable for materials with up to 16% by weight contamination and are guaranteed to remain in use for long periods without changing the filter. Our ERF melt filters are capable of processing a wide range of polymers (e.g. LDPE, LLDPE, HDPE, PP, PS, ABS, PC / ABS, TPE, TPU, POM). All solid or elastomer foreign particles such as paper,wood, aluminum, copper, rubber, silicone, or high-melting polymer composites are efficiently removed.
The classic application for ERF melt filters is repelletizing lines, but they are also successfully employed for sheet and profile extrusion. ERF melt filters can in principle be used in any extrusion line – either single or twin-screw and irrespective of the type of pelletizing system or other downstream unit. Three different sizes enable throughputs from 150 to 10,000 kg/h depending on the application.

CSC-R - Screen changer with curved filter screens

MAAG’s CSC-R large scale screen changer with curved screens is designed for the use of one-way filter screens which do not require cleaning after the simple and safe screen change. The screen bearing pistons belong to MAAG’s modular filter system and its patented design use 75% of the piston surface as active filtration area. Also this filter execution can be installed for vertical or horizontal melt flow directly at the reactor discharge melt pump or pelletizer booster melt pump to avoid additional piping for reduction of melt residence time.

Suitable for Resin & Virgin Polymer Production

CSC-C - Polymer filtration for polymer production, polymer processing and extrusion

MAAG’s CSC-C large scale screen changer with candle filter elements is the right choice if short melt residence time, small footprint and a simplified candle change are required. Depending on the polymer type, melt viscosity, reactor throughput, and filter fineness, the screen changer size and number of pistons are customized to the application. The patented design allows the use of pleated micronex® candle filter elements with fiber metal felt (FMF) media, or cylindrical Multinex candles filter elements with interchangeable filter sleeves.
