In traditional long radius elbow installations, the pellets slide along the elbow wall at a high velocity. The strong centrifugal forces press the pellets against the outer metal surface. This causes friction which creates heat that melts the outer layer of the pellets, resulting in a thin film build-up along the surface of the wall. This build-up eventually breaks loose, forming unwanted streamers and fluff that lead to product contamination. Abrasive materials wear out the elbow walls quickly due to these high frictional lorces. The Pellbow® is especially designed to minimize damage to the elbow and the conveyed product.
Pelletron's experienced Bulkmatology® team provides Pneumatic Conveying and DeDusting solutions for the Plastics Industry. Whether it's de-bottlenecking existing systems or designing complete turnkey plants from the ground up, Pelletron's extensive know-how and experience ensures that solutions are efficient, cost-effective and meet the industry’s highest standards of quality.
Pelletron developed the DeDuster® for removal of dust and streamers. Pelletron offers various types and sizes of DeDuster® for all kind of applications. Pelletron provides dilute,-dense and STRANDPHASE® conveying systems, as well as a complete component program of medium and high pressure rotary, diverter valves and Pellbows®. Pellbows® are especially designed to minimize damage to elbows and conveyed product. Pellbows® avoid the creation of streamers and reduce dust, and are available in wear resistant versions as well.
