separation and recovery process of plastic films and cellulose fiber present in waste from papermaking from post-consumer chips

摘要

SEPARATION AND RECOVERY PROCESS FOR PLASTIC FILMS AND FIBER OF CELLULOSE PRESENT IN THE WASTE OF PAPER MANUFACTURE FROM POST-CONSUMPTION EDGE. Waste from papermaking from post-consumer waste is dosed by an inlet hopper over the feeding mat of the separation tank, in which very dense or large volume contaminations are removed in the first region of the tank and the fiber cellulose and plastic films move to the second region. In this region, the flotation of plastic films occurs, which are removed by a mat. The cellulose fiber is removed with the circulating water. The films are then ground, washed and centrifuged to remove excess surface moisture. Then they are compacted in a continuous compactor and are ready to serve as raw material for the plastics processing industry.
