ABSTRACT:
Process and apparatus for the recovery of both cellulosic fibers and plastic material from plastic-coated papers and boards.
This material is wet-pulped in water suspension, and the suspension is then discharged into dilution tanks for floating most of the plastic material at the upper region of the suspension, wherefrom the plastic material is mechanically separated by wire-mesh conveyors, and washed in a rotating screen.
The fibrous suspension is screened in a rotating screen to eliminate the residual plastic material.
