How To Shred And Sort Mixed Waste?

Typical suitable mixed waste includes:

Home appliance casings (washing machines, refrigerators, air conditioner casings, etc.): Contains steel or iron frames, aluminum or copper heat sinks, and plastic panels.Motor, transformer, and coil housings: A mixture of metal and plastic/insulating materials.Plastic trim and metal frame components in automobiles.

Electronic product casings: Plastic, aluminum alloy frames, and metal accessories such as screws.

These materials typically exhibit characteristics such as a mixture of multiple materials, the presence of plastic or insulation on the surface, and irregular shapes and sizes.For mixed plastic and metal waste, Honest's scrap waste shredding and sorting line typically includes the following steps:

1. Feed shredding (shredding + primary shredding): First, shred or cut larger plastic/metal composite parts to reduce their volume and form a large mixture.

2. Hammer crusher: Further breaks the mixed material into smaller, uniform particles.

3. Magnetic separation: Initially separates ferromagnetic metals.

4. Screening (rotating screen): Separates materials by particle size, such as large, medium, and small particle mixtures.

5. Eddy current separator: Separates non-ferrous metals (such as aluminum and copper) from plastics within each particle size output.

6. Splitting force or air/light/heavy separation devices (such as cyclone/air flow filtration): Helps separate lightweight plastics from heavy metals.

7. Dust removal and environmental protection facilities: This is because plastic or dust can cause pollution during the crushing process.
