METHOD FOR RECOVERING PVC AND URETHANE FOAM FROM COMMINGLED TRIM WASTE USING ELUTRIATORS

摘要

METHOD FOR RECOVERING PVC AND URETHANE FOAM FROM COMMINGLED TRIM WASTE USING ELUTRIATORS A method and apparatus for reclaiming urethane foam and polyvinyl chloride plastic material from composite plastic articles (18). The articles pass through a granulator (23) and pass through a first elutriator (36) where two streams of particles are formed. A denser stream passes to a second elutriator (50) where at its exit (56) substantially pure polyvinyl chloride particles are passed into bin (58). A less dense stream of particles pass to a screen separator (C4) where intermediately sized particles are sorted onto conveyor (74) which passes substantially pure urethane foam to baler (76).
