PURPOSE:To make screening operation lesser in man power and higher in effi ciency and to reduce a treatment cost by constituting the above method of synthetic resin bag pulverizing stages, steel can recovering stage, aluminum can recovering stage and refuse recovering stage for recovering other refuse and fine pieces of the pulverized synthetic resin bags together. CONSTITUTION:This method consists of the synthetic resin bag pulverizing stages 3, 5 for pulverizing the synthetic resin bags housing the steel cans, aluminum cans and other refuse to the desired fine pieces by means of rotating blades 19, the steel cans recovering stage 29 for screening and recovering the steel cans by magnetically attracting the steel can from the steel cans, aluminum cans and the other refuse, the aluminum cans recovering stage 49 for screening and recovering the aluminum cans by the eddy current generated in the aluminum cans by a permanent magnet and the AC magnetic field acting on the aluminum cans by a rotating permanent magnet and the refuse recovering stage for recovering the other refuse and the pulverized fine pieces of the synthetic resin bags together. |
