ABSTRACT:
Scrap sheet floor covering is recovered for reuse through the use of a Henschel mixer. The mixer grinds the prediced scrap in the presence of a plasticizer to separate the asbestos containing backing material from the vinyl layer. The resultant blended mix can then be used as a raw material in the manufacture of fiber-filled vinyl tile.
