Separation Performance of PVC and PP Plastic Mixture Using Air Table

The aim of the research presented in this article was to investigate separation performance of the air table when separating a binary mixture of plastics. Separation using the air table, i.e. a dry mechanical process that grades constituents of the mixture with differences in specific gravity, is employed for separation of the PVC/PP mixture. Moreover, the performance of the laboratory-scale air table is improved by increasing the height of riffles laid on the porous deck.
