Even more interesting for in-house recycling is machine fam- ily number 2, which is dedicated to agglomeration. The Pall- mann Plast-Agglomerator System, PFV, generates fl owable granules with high bulk density from light-weight materials. Here, processing takes place under the melting point, thus material is not thermally stressed. The agglomerates can also be produced from mixed products, i.e. from different plastic materials, additives and fi llers. Pure production waste such as fi lm, fi bers and foam are reusable up to 100 percent. Produc- tion waste consisting of numerous plastics or which contains other materials – such as additives, and fi llers likeminerals and paper – can be transformed into granules which can be used as fi ller and therefore new additives or fi llers are no longer required. Fine grinding is the specialty of the third Pallmann machine family, which makes in-house recycling so interesting. Some applications require powders with a fi neness of 0,5 to 1 mm. This is achieved through fi ne grinding of newmaterial – gran- ulate of 3 to 5mm. If newmaterial is scarce or more expensive, powder is consequently more expensive; the production step from granule to power alone costs up to 30 cents per kg – as a surcharge on granulate pricing. With the Pallmann Disc Mill PKM, a perfect powder can be produced in-house – whether from new material or alternatively from clean recycled mate- rial. „In many countries the ”Pallmann powder” has become a reference. Our customers demand a Pallmann quality powder, most powder suppliers use our PKM in order to achieve the special powder characteristics“, states Michel Marchal. G. Siempelkamp GmbH & Co.
