Clean, reliable 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 fibres are separated off by friction. The soiled material is 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 stabilise the process in the event of fluctuating moisture content of the input material.
