Automated line for sorting municipal waste, plastics and paper

The automatic sorting line for municipal waste, plastic and paper. Designed capacity: municipal waste - 31 t/h, plastic waste - 6 t/h.

Ferromagnetic metals are separated by a pair of overband magnets DND-AC LION and DND-AC JAGUAR.

Subsequently, the material is evenly spread over the entire conveyor belt width (1,500 mm) by a vibrating feeder and is processed by a non-ferrous metal separator. In order to achieve the best possible separation results we have equipped the ECS-E 1500 RAM eddy current separator with an eccentric rare earth rotor. This separator can effectively separate non-magnetic metals from inert material.

The material will be sorted into three material fractions (described in more detail below). A part of the municipal waste ends up in landfills, but most of it is subsequently recycled (metals, plastics, precious metals) or used as input material for the production of solid alternative fuel (SAF) for (mainly) heavy industry.

Finally, the plastics are sorted by color using NIR spectrophotometers and pressed into bales.

The separation line capacity:

• 31 t/h of municipal waste
• 6 t/h of plastic waste
• The sorting line is designed for a capacity of 100,000 tons of municipal waste per year
• Guaranteed separation efficiency: 95 %.

Output

The treated waste is sorted into the following material fractions:

• Heavy fraction - it is intended for subsequent disposal in a landfill
• Metals, plastics – materials to be recycled
• Light fraction - input material for SAF production

The requirements for the possible use of the light fraction as fuel:

• Separated organic fraction
• Separated metals, glass, soil and aggregates
• Hard plastics - sorted by color
• Plastics for secondary use

This sorting line consists of the following equipment:

1. Conveying systems
2. Metal detector
3. DND-AC Mp3 F LION and DND-AC Ms5 F JAGUAR overband magnets
4. Vibrating feeder
5. ECS-C 1500 BULL - non-ferrous metal separator - eddy current separator with an eccentric rare earth rotor – for conveyor belts of 1,500 mm width
6. NIR / VIS spectrophotometer
7. Steel construction
8. Complex control system with PLC outputs
