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

Technical data


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.
