ADG screen changers dramatically cut waste

    March 4, 2015
    Self-cleaning screen changers:  ADG Solutions is offering these improved continuous, self-cleaning screen changers from Fimic Officine Meccaniche srl. The units are especially suited for reclaim extrusion streams and other applications where contamination is a problem. The melt filtration unit, positioned at the extruder outlet, can remove contaminates as small as 150 microns. As contamination builds up on the screen, inlet pressure increases to set point, triggering a scraper that removes contamination from the face of the screen filter.

    What's new?  The control programming. Screen changes typically channel polymer melt through a discharge valve to purge contaminants from the unit. These units store the contaminants from up to six scrapings and discharge all the accumulated contamination at once. The units also feature laser-cut screen plates for durability.

    Benefits  Dramatic reduction in the amount of polymer needed to purge contaminants filtered from the process stream. The amount of wasted resin can be cut in half or even two-thirds.
