ABSTRACT:
A method and an apparatus for separating of different plastic products, which plastic products are comminuted, purified, and dried in a conventional way. The dry particles are fed to a heated, movable support base. Plastic particles, having a lower softening point, adhere to the support base, and particles having, a higher softening point, flow freely over the particles adhering to the moving support base and can be separated. After separation of these particles, the adhering particles are scraped from the steel belt.
