PROCEDURE AND DEVICE FOR THE RECYCLING OF A MIXTURE OF POLYMETHYL METHACRYLATE AND / OR ACRYLONNITRILE-BUTADIENE-STYRENE AND METHYLLATE OF RETICULATED POLYMETHYL.

摘要

Device for recycling a mixture of polymethyl methacrylate (PMMA) and / or acrylonitrile-butadiene styrene (ABS) and cross-linked polymethyl methacrylate, comprising means (2, 8a, 8b, 8c) for feeding said pressure mixture to a first filtration station (15a), a second filtration station (15b) and a third filtration station (15c) placed in series, said stations being arranged to reduce the size of the crosslinked PMMA particles present in the mixture until below 200 microns, each station comprising at least one filter, characterized in that two consecutive filters are separated from each other, these filters being supported to remain separated when loaded by the pressure of said mixture.
