Moventas is to supply mechanical power transmission equipment for drum pulpers manufactured by Andritz. This is Moventas’ largest single order for drum pulper ring gears. Start-up inspection services are also included, with deliveries scheduled for 2010. The value of the order will not be disclosed.

The Moventas delivery consists of 15 multi-segmented ring gears, each with a two-stage Santasalo® D-series gear unit and auxiliary drive gear. The agreement also includes start-up inspection services, which ensure the installation of the mechanical drives. The Moventas multi-segmented ring gears are for Andritz customers in China and Korea where the drum pulpers will be used to produce the raw material for recycled paper and board manufacturing.

Moventas has experience and knowledge in multi-segmented ring gear solutions gained over three decades. This, together with a history of long-term cooperation, made Moventas the ideal choice for a technically skilled and reliable partner in ring gear solutions for drum pulpers.

Moventas developed the multi-segmented ring gear concept with a ring composed of many individual segments, rather than two or four seen in traditional designs. The concept offers significant cost advantages in design, manufacturing, logistics, maintenance and replacement investments.

Multi-segmented ring gears are used in grinding mills, kilns, dryers and debarking drums in various industries, including pulp and paper, mining and minerals, steel, sugar, cement and chemicals.
