The screen basket of the WiPa friction washer/separator has been enlarged by up to 30% so that a considerably larger quantity of contaminants and liquids can be separated.

The canted lids ensure continuous turning of the material, which significantly improves the separation of impurities.

The sieve elements have the same dimensions, which saves storage and spare parts costs, as the elements can be interchanged or simply replaced. In the intake 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 of these. Due to identical dimensions of the sieve plates in the front and rear part of the machine, it is possible to change the sieve elements from front to rear.

This saves on spare parts costs, as the screen plates can be used for longer. Separate sieve elements additionally allow the use of different sieve perforations. For example, a larger screen perforation can thus be installed in the feed area of the machine than in the rear area of the machine.

The screen perforation can be individually adapted to the material. Round screen perforations between 2 and 3 mm are used as standard. However, other sieve bars with e.g. conical or angular perforations, as well as special sieve elements for e.g. the preparation of fibers or big bags can be supplied. The new screen design provides a much larger screen area than comparable equipment, significantly increasing separation, washing and drying results.
