SELECTING METHOD OF MIXTURE HAVING METAL, RESIN AND INORGANIC FIBER

PROBLEM TO BE SOLVED: To provide a selecting method for selecting from with high purity a mixture of a metal, a resin and inorganic fibers, in a mode capable of reusing them individually.SOLUTION: A selecting method for selecting from a mixture of a metal, a resin and inorganic fibers comprises: a crushing step of obtaining a crushed debris crushed from a mixture of a metal, a resin and an inorganic debris; a refining step of pouring the crushed debris into a pulverizing classifier having a mesh thereby to refine the crushed debris; a resin selecting step of selecting the resin through the mesh from the crushed debris; and a metal and inorganic fiber selecting step of selecting the metal and the inorganic fibers individually from the crushed debris. A metal and inorganic fiber selecting step is performed after the refining step.SELECTED DRAWING: Figure 1 【課題】金属、樹脂及び無機繊維の混合物からの選別を、それぞれが再利用可能な態様で高純度で行う。【解決手段】金属、樹脂及び無機繊維の混合物を破砕した破砕片を得る破砕工程と、メッシュを有する粉砕分級機に破砕片を投入して微細化する微細化工程と、メッシュを介して破砕片から樹脂を選別する樹脂選別工程と、破砕片から金属及び無機繊維それぞれを選別する金属及び無機繊維選別工程と、を含み、微細化工程の後に金属及び無機繊維選別工程を行う。【選択図】図１
