Abstract

Fluidized bed medium separation (FBMS) was applied for gravity separation of plastics containing or not C1 for recycle of home electric appliance shredder residue. We employed mixtures of glass beads (G.B.) and polystyrene particles (P.S.) with various mixing ratios as fluidizing particles. Floating and sinking of the plastics were examined by changing the bulk volume fraction and the superficial velocity u0. The plastics were almost completely separated at the conditions of G.B. : P.S. = 8 : 2 and u0/u mf= 1.5 where umf is the minimum fluidization velocity. Similar experiments were carried out by changing dimensional parameters of plastics, such as equivalent volume diameter Dv, flatness ratio Rf and aspect ratio Ra. As a result, it was found that influence of Dv on float-sink behavior was the highest and contribution ratio of Dv was about 75%.
