This equipment is used to process various large radiators (copper and aluminum water tanks) or motor rotors (with shafts) less than or equal to 15cm in size. The material is roughly crushed by the first crusher, and then crushed by the second crusher. The crushed material is 3cm in size, and the iron is separated by magnetic separation, and then air-separated by air. The equipment has novel structure, beautiful and unique appearance, and large production capacity; the whole line is controlled by PLC program, and one feeding can be completed by multiple machines; it is equipped with automatic shutdown and overload automatic alarm device. The successful development of this treatment line has greatly liberated productivity, improved the quality of metal recovery, and at the same time recovered the advantages of iron. The most important thing is to effectively solve the overflow of dust during the treatment process and reduce air pollution.
