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 u_mf is the minimum fluidization velocity. Similar experiments were carried out by changing dimensional parameters of plastics, such as equivalent volume diameter D_v, flatness ratio R_f and aspect ratio R_a. As a result, it was found that influence of D_v on float-sink behavior was the highest and contribution ratio of D_v was about 75%.
