Separate
WIPA separation tank
Type WSST
The WIPA separation tanks type WSST are used for separating and separating a wide variety of materials due to their specific density, e.g. for separating PET or PVC from PE or PP regrind.
WIPA separation tank
The process
Explanation using the example of PP/PE separation in PET bottle recycling: The pre-shredded material is fed into the separation tank via 2 screws below the water surfaces. As PET is heavier than water, it sinks to the discharge unit for the sediment and is conveyed out of the machine by a screw or scraper chain conveyor. PP and PE, on the other hand, rise to the surface of the water and are conveyed to the floating material discharge by various paddle drums connected in series and pressed under water several times in order to separate any PET that may still be adhering. A Frictionwasher is usually installed downstream of a separation tank, as this can separate large quantities of liquid from the material.
Modular
The WIPA separation tanks of type WSST are available in various sizes and can be adapted to larger or smaller throughput capacities after installation thanks to their modular, expandable design.

Cleaning and drying
WIPA pre-wash screw
Type EWS
Type DEWS
The WIPA pre-wash screws are used for washing, rinsing, soaking and separating sinking contaminants such as stones, sand or glass.
WIPA pre-wash screw
The process
The material is fed into a pre-wash tank on the underside of the pre-wash screw and pressed under water by paddle rollers. The material is then conveyed to the top by 1-2 screw conveyors. The material moves a lot during transportation, so contaminants such as stones, sand, glass and metals can easily sink. In addition, the adhesions on the
plastic, so that they can be removed more easily.
Different discharge systems can be used depending on the type of contamination. Simple, small contaminants such as stones or glass are removed via a time-controlled pusher system. For larger or long contaminations such as wire, or larger quantities of contamination
scraper chain conveyors or screw conveyors are used to discharge contamination.

Cleaning and drying
WIPA Frictionwasher
Type FW
The WiPa Frictionwasher/separator type FW is used for intensive washing, but also for dewatering plastics.
WIPA Frictionwasher
The process
The material is fed in at the bottom of the Frictionwasher/separator and conveyed to the top by the throwing blades attached to the internal rotor. During transport, the material is repeatedly thrown against the screen basket around the rotor, which cleans the material and separates out water, paper fibers, sand and other contaminants.
Strainer basket
The screen basket of the WiPa Frictionwasher/separator has been enlarged by up to 30% so that a significantly larger amount of contaminants and liquids can be separated.
The edged lids ensure continuous turning of the material, which significantly improves the separation of impurities.
The screen elements have the same dimensions, which saves storage and spare parts costs, as the elements can be interchanged or simply replaced. In the feed area of the machine, the screening elements are subjected to greater stress than in the rear part of the machine, which results in higher and faster wear. Due to the identical dimensions of the screen plates in the front and rear part of the machine, the screen elements can be changed from front to rear.
This saves on spare parts costs, as the screen plates can be used for longer. Separate sieve elements also allow the use of different sieve perforations. For example, a larger screen perforation can be installed in the infeed area of the machine than in the rear area of the machine.
The screen perforation can be individually adapted to the material. Round perforations between 2 and 3 mm are used as standard. However, other screen types with e.g. conical or angular perforations, as well as special screen elements for e.g. the processing of fibers or big bags can be supplied. The new screen design offers a much larger screen area than comparable systems, which significantly increases the separation, washing and drying results.
Rotor
The rotors of the FW series are equipped with replaceable throwing blades. This makes it possible to use a wide variety of materials and geometries, tailored to your material. Another advantage of the replaceable throwing blades is that the rotor itself only acts as a carrier and is subject to virtually no wear. The rotor has a peripheral speed of approx. 30 m/s during operation, which exposes the material to very high centrifugal forces that ensure optimum separation of material and contamination, as well as liquids.

WIPA intensive cleaner
The process
The material is fed in at the top end of the housing. The material is conveyed to the discharge side by the internal rotor and the exchangeable throwing blades mounted on it. As the material enters the machine, it is greatly accelerated, forcing contaminants such as paper fibers, sand and organics as well as adhering water through the holes in the screen basket. To achieve a consistent result, the screen basket is cleaned continuously. Depending on the type and degree of soiling and the use of the machine, different systems can be used to remove the soiling.
