Technology of dismantling and recycling waste wires and cables of cable wire recycling machine
Dry-type cable wire recycling machine dismantling and recycling waste wires and cables can not only avoid environmental pollution, but also save resources, which has important economic value. This paper compares the advantages and disadvantages of different recycling methods, and proposes that the machine dry crushing and sorting of copper rice will become a development trend of waste wire and cable recycling.
The mechanical method resource dismantling technology of cable wire recycling machine equipment is currently a widely used method at home and abroad. It is characterized by simple mechanical equipment structure and mature operation technology. The principle is to use mechanical scissors to crush wires and cables into particles, and then use specific gravity, magnetic or electrostatic separation methods to separate the crushed non-metals and metals.
cable wire recycling machine equipment is divided into dry cable wire recycling machine and wet cable wire recycling machine. The wet process is a more traditional method, mainly using washing shaker sorting technology. This process uses a lot of water in the production process, so this method will cause waste of water resources and secondary pollution. The dry cable wire recycling machine refers to a sorting method that does not need to add water during the sorting process, and mainly adopts relatively environmentally friendly methods such as wind sorting, vibration sorting, and electrostatic sorting.
Dry copper rice mills generally include crushing separation, sorting, dust collection, magnetic separation and other systems. Crushing and separation usually include crushers, pulverizers and other auxiliary equipment. Magnetic separation facilities are usually installed after the crusher and pulverizer. Since the iron obtained after magnetic separation contains some undetached plastic and copper, a set of degumming machine can be installed to realize the separation of iron from plastic and copper. In order to achieve the purpose of removal.
Sorting: including separation equipment, specific gravity sorting equipment and other auxiliary equipment. The separation equipment mainly separates the miscellaneous materials produced by crushing. The gravity separation equipment mainly separates copper and other precious metals and plastics through gravity separation.
Dust collection: including cyclone dust collector, bag dust collection system, all crushers, shredders, separation equipment, specific gravity separation equipment and other equipment that may generate dust should be equipped with dust collection systems. After dust collection, exhaust gas is discharged uniformly,
Magnetic separation: After the crusher and the pulverizer, a magnetic separator is installed to remove iron, increase copper purity and protect knives.
Dry-type cable wire recycling machine crushing and separating wires and cables has the advantages of high automation, large processing capacity, high processing efficiency, and good environmental protection effects, which will become a development trend of waste wire and cable recycling. Dry-type cable wire recycling machine cable wire recycling machine belongs to resource recovery machinery, which has the advantages of high degree of automation, large processing capacity, high processing efficiency and good environmental protection effect. The main basis for the selection of dry cable wire recycling machine equipment refers to the incoming materials and processing volume of the waste wires and cables to be processed.
