Automated line for sorting PET bottles, Al and Fe cans
This automatic sorting line is designed for a capacity of 4,500 kg/hour and is used to treat waste material kept in “yellow bins”, i.e. PET bottles, aluminum and iron cans.
Firstly, material bales are unpacked and the material passes through a trommel screen.
Afterwards, ferrous cans are separated by a pair of very strong DND-AC TIGER overband magnets.
The reliable separation of aluminum cans is performed using the ECS-C RAM eddy current separator with a concentric rare earth rotor. Before being processed by the ECS separator, the material is spread on the conveyor belt by a vibrating feeder (the uniform material distribution is a prerequisite for the proper functioning of the ECS separator).
Finally, the PET bottles are sorted by color using a NIR / VIS spectrophotometer.
The individual types of the sorted materials are pressed.
The functionality of the entire sorting line and its parts is monitored by a camera system. The advantage of such a system is the possibility of remote access to individual control elements of the sorting line.
- The separation line capacity: 4.5 t/h + 3.5 t/h (Al packaging)
- Guaranteed separation
Output
The treated waste is sorted into the following material fractions:
- 3D PET bottles
- Aluminum cans
- Iron cans
The sorting line consists of the following equipment:
- Conveying system
- ECS-C 1000 RAM eddy current separator with centrically mounted rotor - for conveyor belts of 1,000 mm width
- NIR / VIS spectrophotometer
- Trommel screen
- Accumulation storage boxes
- Automatic baler
- Crushers
- Steel construction
- Complex control system with PLC outputs directly on the sorting line
- Remote access
- Camera surveillance
This line is designed for sorting waste from yellow bins — material whose main components are PET bottles, aluminium and steel cans — at a capacity of 4,500 kg/h. Compared to the 5 t/h line, it offers a more compact solution with an ECS separator for a belt width of 1,000 mm and two DND-AC TIGER self-cleaning magnetic plates; the municipal waste line is recommended where the input mix also contains organics, paper and light fraction.
The line is designed to process 4,500 kg of material per hour; for aluminium packaging it reaches a capacity of 3,500 kg/h. The guaranteed separation efficiency is 95 %.
Separation takes place in three successive steps: ferromagnetic steel cans are first captured by two DND-AC TIGER self-cleaning magnetic plates placed above the conveyor belt. Aluminium cans are then separated from PET bottles by the ECS–C 1000 RAM eddy-current separator with a concentrically mounted rotor for a belt width of 1,000 mm; PET bottles are finally sorted by colour using a NIR/VIS spectrophotometer.
The vibrating conveyor distributes the material evenly across the belt just before it enters the ECS separator. Uniform layer distribution is a prerequisite for correct eddy-current separation — without it, the efficiency of aluminium can recovery could be reduced.
The separated steel and aluminium cans are processed by pressing equipment and crushers directly within the line. The result is three clean secondary raw materials — 3D PET bottles, aluminium cans and steel cans (pressed and crushed) — ready for direct sale.
The line is equipped with camera surveillance and a PLC-based control system; remote access to the controls is also included in the delivery, enabling operators to monitor operations and diagnose any issues without having to be physically present on site.
Every sorting line is designed and manufactured to order according to the specific type of material, its granulometry and the required capacity. We also supply lines for sorting municipal waste, plastic waste, glass and other materials — the equipment configuration is always tailored to the specific application.
The delivery covers the entire process — from site survey, design and custom manufacture through installation, commissioning and operator training to authorised service for the full service life of the equipment. We provide a warranty of up to 10 years on magnetic components; prior to ordering we offer free testing of your material with a guaranteed turnaround of three days.
