PROBLEM TO BE SOLVED: To improve accuracy in screening of ceramics obsolete waste inorganics discarded by a method wherein ceramics are selected into broken ones and unbroken ones, the broken ones are further selected into white ones and brown ones, they are respectively separately stored, a specific amount thereof is cut out to be crushed with crushers ranging over several stages, and classified by wind selection. SOLUTION: Various kinds of ceramics are selected into broken ones and nonbroken ones, the broken ones are further selected into white ones and brown ones, and they are respectively independently stored in separated hoppers. A specific amount of ceramics and pottery is discharged out to be applied to a primary crusher, and then a specific amount thereof is fed to a secondary crusher. Then, the ceramics and pottery after being crushed, which is discharged from the secondary crusher, is refined in a powdery state with a cullet crusher. The ceramics generated in a powdery state are blown together with wind force generated with the secondary crusher, and the powdery ceramics and pottery are classified. The classification is of a four stage type wherein a first mesh is 15 mesh over cap and label group, a second mesh is 2.5×2.5mm mesh, a third mesh is 2×2mm mesh and a fourth mesh is 1.2×1.2mm mesh from an upside. |
