The system combines the washing and grinding of plastic waste such as bottles (PET), film (pre-cut in a guillotine) etc. One application is also the treatment of the sinking fraction of the float/sink-process.   The patented principle of the system is derived from the mechanical design of the Costarelli densifier, and combines the shredding effect of the rotor blades and the washing caused by injected water and the mutual friction of the plastic particles. Tangentially injected air avoids that the plastic particles stick to the side walls of the drum.

The process is batch-wise. The material is loaded from the top and after the washing cycle discharged through a laterally located hydraulically operated flap. The residual humidity is about 20 % so that the material must subsequently be dried. We recommend centrifuges or thermal dryers.

The washing water is discharged through the bottom of the drum. A sieve separates the material from the residues of the washing process. The water can be recirculated before it has to be treated in a simplified water recirculation- and treatment plant.
