The dirty water created by the washing process is collected and cleaned and can be reintroduced into the circuit, which significantly reduces the water consumption. Herbold Meckesheim offers all the elements required for this circuit.

The hot washing stage serves not only for the removal of adhesives, but also for washing out remaining impurities in the flakes, such as sugar, soda residues, etc.

Swim-sink tanks use the specific weights of the various kinds of plastic to separate them.

The material which is simultaneously washed and granulated in the wet granulator falls into a dewatering screw, which separates the dirt dissolved in the water.

Herbold mechanical dryers for washing lines are highly efficient machines which work on the centrifuge principle. These units achieve excellent drying results, which in the case of many materials dispense with the need for subsequent thermal drying.

One of the last stages of the washing process is to dry the materials to a processing-capable residual moisture content, which can be between 0.5 and 10%.

Foreign body separators work according to the sink-or-swim principle, i.e. according to the different specific weights of the various components of the input materials, so that it either floats to the surface of the water or sinks to the bottom.

The VWE pre-washing unit combines the function of a foreign body separator with a pre-wash of the feed material. In three integrated process steps, the Herbold pre-washing unit separates foreign bodies such as stones, metals, glass, sand and paper from the shredded material, subjects the feed material to an intensive washing process and finally makes any more foreign bodies sink to the bottom
