Plastic recycling plants use compressed air for sorting, conveying, washing and extrusion, in an environment full of dust, moisture and process heat. The equipment must be robust and the air supply reliable across continuous operation.
Key applications
- Optical and air-knife sorting of flakes
- Pneumatic conveying of ground material
- Washing and drying line actuation
- Extruder and pelletising controls
- Baling and packaging systems
Air quality
Control air must be dry and oil-free for reliable valve operation. Sorting and conveying air needs drying to prevent material clumping, with heavy-duty intake filtration to protect the compressor from plastic dust and fines.
Specification notes
Choose machines rated for dusty, humid conditions and clean coolers frequently. Variable speed control follows the fluctuating load of batch washing and extrusion, and redundancy keeps the recycling line moving.
