Recycling solutions for tires
ANDRITZ MeWa has also shown a pioneering spirit in the processing of scrap tires. The guiding principle for worn, used tires and the waste from manufacturers’production processes is the same – recycling instead of incineration. The secondary raw materials obtained go back directly into new tires or other products.
The objective of tire recycling is to break down the used tires into their individual components – rubber, steel wire, and textiles. ANDRITZ MeWa plants recover the raw materials in a multi-stage recycling process that achieves highest levels of purity.
- Pre-shredding: Universal rotary shear UC: Shreds the tires into hand-sized pieces (70-100 mm)
- Granulating: Universal granulator UG: Granulates the pre-shredded tires to granules measuring 8-10 mm
- Fine granulating: Universal cutting mill USM: Granulating to a size of < 4 mm
- Fine milling to produce rubber powder
- Separation/cleaning after every granulation step
Rubber granulate from used tires
Throughput of the plant: 3-20 t/h (depends on the size of the machine and the material mix)
