Processing polymer additives with this pelleting press
Amandus Kahl
The polymer industry uses a great variety of additives. They are used to stabilize polymer structures, to prevent damage to the final product by heat, shear energy and oxidation, for pigmentation and for ultraviolet (UV) protection. Many of these additives are already processed on Kahl flat-die pelleting press (photo). In the flat-die pelleting press, the pan grinder rollers rotate on a horizontally arranged flat die (disc die). They press the product from above in the axial direction through the bores. Materials, dimensions, surface profile and number of rollers can be varied according to product and throughput. The press is available from laboratory scale up to production capacities of more than 1 ton/h. The pellet diameter is typically 2–3 mm. Hall 10, Stand H08 — Amandus Kahl GmbH & Co.
