<p>The present invention relates to an CRUSHERS. Above-mentioned invention is used to crush every crushable thing such that is not decades occurs environmental, and inferior plastic in order to recycle them easily. And metallic impurities can be filtered off with electromagnet or magnet thus makes only pure plastic pieces. The present invention makes fine plastic pieces over 1st and 2nd crushing process. Therefore it improves the quality of goods when used in producing line. Also, for the crusher crushes over the 1st and 2nd time, crushing work is done in short time and more efficiently. Owing to the sensor installed to hopper part of above-mentioned crusher, the crusher operates only in supplying recyclable plastic, so unreasonable rod is not loaded on the operating part and power waste is reduced, thus improves economical efficiency. Meanwhile, when not in use for long time, sensor senses it and control unit box stops operation of crusher. It leads longer life of machine, enables to set labors in place, reduces usage of industrial water and power waste according to stopping. In addition, shape of punch block, guide block and punch rod of the 2nd crusher is not limited by machines and varies with shapes, thus useful for environmental industry or recycling industry.</p> |
