Abstract

PURPOSE:To effect a captioned disposal efficiently and continuously by separating effeciently as well as removing perfectly adhered or mixed foreign substances under utilizing differences of specific gravities and reproducing as fuel or pellet type wastes. CONSTITUTION:Plastic wsates are thrown into a roll crusher 2 by a belt-conveyor 1 and are crushed by difference of rotations of a pair of crushing rollers having different rotational directions, then, are thrown into a washing tank 8 and wastes floated by revolving water stream are introduced into a hot-water washing tank 13, thus, adherred substances and mixed foregn materials are separated by sinking. Crushed plastic coming from an outlet of a revolving screen 18 for drying device 17 is thrown into a heavy water tank 20 filled with heavy water having a specific gravity of more than 1.5, thereafter, crushed materials coming through a floating separator 22 are thrown into a water tank 24 having a V-shaped bottom, thereby, crushed vinyl are sunk by utilizing differences of specific gravities and are introduced into a silo 27 in which they are formed into pellet shape. Floated polyethylene and the like are collected and sent to an operating process for forming fuel.
