The world’s largest steel yankees to C&S Paper Yunfu


Group Andritz has received an order from C&S Paper Yunfu, Luoding, Guangdong Province (China), to supply two PrimeLineST tissue machines, each equipped with a steel yankee. Start-up is scheduled for the end of 2013. The tissue machines have a design speed of 1,900 m/min and a width of 5.56 m. The steel yankees will be 18 ft in diameter with a shell length of 6.2 m, making them the world’s largest steel yankees for tissue. Andritz’s scope of supply also includes the complete stock preparation plant as well as automation and drive systems. These will the first PrimeLineST machines in China. The design of the PrimeLine ST is to reduce energy consumption in the drying process, which uses relatively cheap steam only. A large, high-precision steel yankee is combined with a steam-heated hood to achieve the maximum possible output at stable runnability, and this is achieved with significant cost savings.
