WEAR PROTECTION of the UWP is optimized

The BKG Bruckmann & Kreyenborg Granuliertechnik GmbH has broad experience in the area of wear resistance. Due to continuous improvement of the various components it has been possible, over the last five years, to reduce the cost of wear & tear on the machinery by 50%.

When producing glass-filled plastic compounds, it is inevitable that wear to the machine components will occur. However, the BKG pelletizing systems which have been specially developed for this application offer significant advantages.

In particular when dealing with high material throughput levels of up to 6 t/hour, the fully automatic pelletizer offers a good return on investment. The familiar strand breaks which occur frequently with conventional strand pelletizing equipment, become a thing of the past. Consequently, the personnel requirement is reduced to a minimum while the amount of scrap is greatly reduced. Together with the quick start-up feature of the underwater pelletizer this results in very efficient production.

Further advantages of the BKG system are the compact design and the closed loop system which prevents dust or steam from entering the production area. The underwater cutting of the polymer melt has Finally, the cutting of the polymer in the molten state by the underwater pelletizing process, has a proven track record in the production of PP, PBT, PC and PA compounds with up to 66% glass fibre.

The cutting chamber, water inlet and outlet are fitted with exchangeable wear resistant liners (highlighted in yellow) that may be quickly replaced whenever necessary. The seal cover on the pelletizer casing and the cutter hub are made of a special, wear resistant material.

The rotor lifters, inlet assembly and outlet assembly are manufactured from wear resistant material. These components (highlighted in yellow) are exchangeable and may be replaced as necessary. The dryer screen has a wear-resistant coating.
