“Essentially, this order was about proven technology combined with the support that we can offer as a global company,” says Stefanie Müller, Area Sales Manager, Bruks Klöckner GmbH, part of Bruks Siwertell. “The customer already knows the capabilities of our equipment and has good experience with it at other pellet mills. Drum chippers are a core component of plants like these. They form part of the wet side of the facility and basically reduce the log to chips.
“At around 2.4 m in diameter, this was one of the biggest drum chippers that we have ever manufactured,” Müller continues. “Logistically, large deliveries such as these, require significant planning and expertise, especially for individual pieces of equipment that are over 100 t and have to make a transatlantic journey.”
At its new location, the type DH 1050 (800) x 1450 K-14W(T) is able to produce up to around 1.5 million tpy of wood chips at a homogenous chip size of between 8 and 11 mm. It offers a capacity of 272 tph and delivers 855 m³/h loose chips, handling tree-length logs between 3.1 m and 15.2 m, short wood, and forest clean-up. For this particular facility, the chipper will predominantly process softwood tree species.
“For pellet plants to compete for sustainable fuel production, they need consistent performance, reliability, and efficiency from their wood-processing equipment; this is exactly what our systems ensure,” Müller concludes.
Bruks Siwertell manufactures drum chippers at its Bruks Klöckner company in Hirtscheid, Germany. More than 11 000 chippers, of various sizes, have been delivered worldwide and are key to many processed wood industries.
