The separation of post-consumer plastics of different polymeric compositions is becoming an
important topic for the reduction of waste and promotion of recycling. The comminution of
plastics creates variable particle shapes which cause difficulties in the separation by a
cyclone. To study the influence of particle shape, tests have been performed to determine
how the partition curve changes with particle shape in cylindrical cyclones. The test results
give a complete picture on the influence of particle shape and size on the cut density d50 …
