During milling e.g. of PET bottles with the paper labels there appears impurities in the form of a paper dust and shredded chips, which are undesirable at the successive stages of PET materials processing in the insulation boards production technology. To liquidate that situation it is used the pneumatic dust removal system removing the a/m impurities from the main stream of the milled materials.
The pneumatic separation system of USP400 Type is assigned for the cooperation both with TRYMET equipment and it can be adapted to the cooperation with the equipment of the other manufacturers as well.
