Sorting / Separation

Herbold Debalers break up compressed bales and briquettes prior to feeding them into shredders or granulators, while Swim-Sink tanks use the different specific weights of the various kinds of plastics to separate them.  The Herbold Heavy Material Separator works on a swim-sink principle. Different specific weights of feed materials will cause them either to float on the water surface or sink to the bottom of the tank.

PVC Label Remover

PVC Label Remover

This innovative system is designed specifically to remove sleeve labels from plastic bottles prior to recycling.

Sink/Swim Tank

Sink/Swim Tank

Swim-sink tanks use the different specific weights of the various kinds of plastics to separate them. Typical applications are the separation of PET or PVC (both sink) from polyolefines, such as PE or PP (both of them swim). The light fraction is transported along the surface of the water by means of paddle drums to a discharge conveyor; the heavy fraction are extracted - depending on its amount - either by a pair of pneumatic valves at the bottom of the tank or by a scrape conveyor mounted below the tank.

Hydrocyclones

Hydrocyclones

Hydrocyclones are used for separation where greater efficiency is required than what is achievable with swim-sink tanks.

Pre-Washing Tank / Heavy Metal Separator

Pre-Washing Tank / Heavy Metal Separator

The function of the pre-washing tank is based on the swim-sink principle i.e on the different specific weights of the various components contained in the feed material that will either cause them to float on the water surface or to sink to the bottom of the tank.

Heavy Material Separator

Heavy Material Separator

The pre-washing unit VWE 600/2 combines the function of a heavy material separator with a pre-wash of the feeding material. The Herbold pre-washing unit separates foreign bodies such as stones, metals, glass, sand and paper using three different integrated process steps. The feed material undergoes an intensive washing step and then, in a third step, makes further foreign materials sink.

Air Stream Separator (SZS)

Air Stream Separator (SZS)

Herbold's SZS air stream separators are used for separating particles of almost constant granule size on the basis of their specific weight.

Herbold Dewatering Screw Type EPS

Herbold Dewatering Screw Type EPS

The dewatering screw is continuously fed with wet and pre-shredded material. Afterwards this material is pushed to the drying chamber and at the same time compressed with the help of a screw with a conical profile. The necessary counterpressure needed for dewatering is applied by a hydraulic ram.
