摘要
Two-stage melt filtration wherein a screen pack changer is placed behind a separation head meets the requirement of a high fineness and long useful life of the filter. This allows the cleaning of recyclable plastics scraps with a high degree of contamination at a much lower overall costs because of the continuous prefiltration which prolongs the life of the screen pack system.
