Trials performed at the Fuchs test centre indicate that with increased sifting surface, the probability of having a long granule falling vertically through the sieve apertures increases. In addition to this, by using inappropriate sifting techniques (for instance a vibrating sieve), these granules will increasingly ‘jump’, into a vertical position and fall through the sieve. Tests showed that the SIFTOMAT offers the best possible conditions for sifting plastic granules, as the sifting movement has no vertical component, as a result of which the jumping effect of the granules is avoided. Additionally, the rectangular shape of the sifter has the advantage that compared to circular units, the sifting width does not increase during the process. Additionally, Fuchs subdivides the sifting surface, the perforated plate, into several segments with perforated and non-perforated plates. Thus, it is possible to adjust the surface of the perforated plates to the required capacity by inserting only as many perforated segments as necessary. The rest of the segments are non-perforated and sieve surfaces that are too large can thereby be avoided. www.fuchsag.com
