Abstract
To provide a high-efficient apparatus for minimizing the volume of dust to be buried in the ground or processed in incineration process by crushing a waste article such as wasted electric appliances, separating an individual material component, and discriminating and extracting valuable resources. Motor and other waste articles separated at a metallic lump separation station are cooled down by a cooling apparatus, and put into a soft crushing apparatus where articles are crushed at low temperature. After the residual articles, including housing and so on are crushed primarily by the coarse crushing apparatus, they are forwarded to the soft crushing apparatus. The coarse crushing apparatus mainly supplies the shear action and, on the other hand, the soft crushing apparatus uses a mixed and integrated mechanical interaction other than shear action including compression, friction, twist and distortion actions, which results that a composite material structure is broken down and separated into individual material components and that those material components are processed by individual materials in the later process done by the metallic material separation apparatus and the plastic mat…
