MAS DRD = A Sustainable Solution for Plastics Recycling

The MAS dry cleaning technology for plastic is a modern and extremely economical alternative – or an optimal supplement – to conventional wet washing lines. Based on the tried-and-true DRD (Double Rotor Disc) technology, the plant combines the cleaning centrifuge with thermo-mechanical drying in OneStep. This special design allows for economic use in a wide range of applications:

  • As a stand-alone drying and cleaning solution for a wide range of plastic film and fibers
  • Downstream of a wet cleaning plant to improve the quality of the washed flake even further (for example, LLDPE stretch film)

The Process

After coarse shredding of the plastic waste, the dry cleaning unit is continually fed from the buffer silo with batches of up to 60 kg. The plastic material rotates in a cylindrical chamber, is engulfed in hot air and kept in suspension. Turbulence ensures an excellent drying effect (constant average moisture content of 2 %). At the same time, impurities such as sand, soil, paper or fibers are separated off by friction. The contaminants are continually discharged via tangential screens as part of the process.

The whole process is fully automated and controlled by an easy to use PLC system. The required performance and retention time can be adjusted individually to reflect the moisture content and degree of contamination. Sensors stabilize the process in the event of fluctuating moisture content of the input material.
