How to crush waste wires and cables to recycle copper meters and plastics

2021-05-18

A large number of waste wires and cables form a lot of garbage every year, which makes environmental protection problems more difficult. After a series of processing methods, the waste wires can get pure copper rice particles and plastics. How to crush waste wires and cables to recycle copper rice and plastics, so that waste materials can be turned into treasures?

The waste wires and cables are crushed by the dry copper rice machine, and the material can be crushed to a particle size of about 12mm; the crushed material is sent to the material storage silo through the feeder; the silo collects the crushed materials, Provide material source for the automatic feeder; then through the automatic feeder, the materials in the silo are evenly fed to the decomposing agglomerator. The function of the decomposing agglomerator is to run the materials in the machine at high speed, and the materials in the machine are at a linear speed. Reaching 85m/s, while running at high speed, strong high-pressure air flow is generated in the machine, which makes the materials collide with each other in the machine and breaks down the combination. Due to the different properties of metal and plastic, the metal wire rotates at high speed. , The copper wire (or other metal wire) is grouped into small balls.

The machine rotates while generating strong high-pressure air volume to discharge the decomposed materials out of the host; the materials decomposed by the decomposing agglomerator are collected in the collector; the collector is used to collect the decomposed materials and remove the materials that are not included. The hot air is discharged; afterwards, the material is sent to the rotating screen through the feeder. The function of the rotating screen is to make the various fibers in the decomposed material bond with each other in the rotating screen, and gradually form agglomeration. The fibrous material spheres are then screened out through a rotating screen machine to form fibrous spheres to separate the fibrous materials and non-fibrous materials. The material after the fiber is removed is separated into a mixture of copper and plastic copper by a specific gravity air separator. Copper refers to the larger copper particles, and the plastic-copper mixture refers to the mixture of plastic and a small amount of fine copper (because the specific gravity of copper is large, the specific gravity of plastic is small, Therefore, the density of the plastic and the larger copper particles are separated in the specific gravity air separator)

The plastic-copper mixture is separated into a mixture of copper and plastic-copper according to the electrical difference of the electrical conductivity of the two materials by an electric separator. Copper refers to a small amount of fine copper with a smaller particle size, and plastic-copper mixture B refers to a mixture of plastic and fine copper powder; the plastic-copper mixture is separated into a plastic and plastic-copper mixture by a rotating copper removal machine: plastic and trace metals are subjected to secondary electrical selection : After removing the copper from the mixture of plastic and fine copper, according to the electrical difference of the electrical conductivity of the two substances, the copper and plastic are electrically separated to form metal, plastic and trace metal.
