Device for crushing plastic products and/or semi-manufactured products in particular for the purpose of their recycling

摘要

To crush products and/or semi-manufactured products of plastic material, for example polypropylene comprising fiberglass or another armoring fiber or from a non-armored plastic material, a supporting frame of a crushing device has a shared space for a first crushing section including a pair of parallel first crushing rolls each fitted with teeth and a second crushing section including a pair of parallel second crushing rolls fitted with teeth. The second section is positioned below the first section and the axes of the second crush rolls of the second crushing section are in the floor projection positioned approximately perpendicular to the axes of the first crush rolls of the first crushing section. The shared space is interconnected with a vacuum source through a filtering device. A feed hopper has a crushed material conveyor.
