<p>A device to separate materials with different mpt e.g. for the reclamation of plastic waste, plastified in an extruder and coated with a metal foil, was described in the Parent Patent No.2837633. The sepg plates with their milled channels are now replaced by a stack of plain rings, alternating with undulating rings, between which the radial screen slots are formed. This results in a simplified low-cost mfr because the sepg plates now require no machining. The sepg efficiency is maintained, however, at the same high level.</p> |
