<p>PURPOSE:To recover a pulverized resin by pulverizing the waste of a glass fiber-reinforced resin, forming a separated mixture by a superhigh-speed eddy current or pressure vibration, blowing the ionized air against the mixture by a vibrating feeder to separate the mixture into glass fiber and resin and dropping the glass fiber by a wire net. CONSTITUTION:The formed waste is coarsely crushed, and the coarsely crushed material 4 is recovered (A) through a cyclone 3. The material 4 is introduced into a pulverizer 6 and pulverized, and a pulverized material 7 is obtained (B) as a mixture of the glass fiber and resin by the superhigh-speed eddy current generated at the rear of an impeller and the high-frequency pressure vibration. A vibrating screening machine 13 is provided with a vibrating screen 13a consisting of a 6-mesh wire net, while the oversize 14 contg. the glass fiber in the pulverized material 7, fine glass fiber and primary fraction 15 are sieved by the wire net, the glass fiber is positively charged and the resin is negatively charged. The materials are destaticized (C) by blowing the air ionized by a corona discharge in a destaticizer 12 and separated (D) by a vibrating feeder 18.</p> |
