Print Print this article | Send to Colleague

Hengan Group, Jinjiang, China, has started up the world's largest steel Yankee dryer for tissue production. Supplied by Andritz, Graz, Austria, the PrimeDry Steel Yankee (4.9 m dia and 6.2 m shell length) is installed in the new Andritz PM 15 tissue machine, and enables safe and energy-efficient machine operation, the company notes.

"We have eight Andritz tissue machines in operation. PM 15 with the world's largest steel Yankee for tissue is now the icing on the cake," says Zhang Qunfu, chief engineer at Hengan Group. An additional Andritz machine with a steel Yankee will be started up later this year at Hengan, one of the leading tissue producers in China.

PM 15 (a PrimeLine W6 model) has a design speed of 2,100 m/min, a width of 5.6 m, and is equipped with energy-saving components such as Yankee head insulation and a re-evaporation system. Andritz's scope of supply also includes the complete stock preparation system and machine controls. The machine was started up two weeks ahead of schedule.
