HengAn has set a new speed record for an Advantage ViscoNip press at its Weifang mill in Weifang, Shandong province, China. The Metso (Finland)-supplied Advantage DCT 200 tissue production line, equipped with the Advantage ViscoNip long-nip press, has been running at a record breaking speed of 2,000 m/min on average for more than one month at the mill.

"We would like to express our appreciation to fellow workers in the front line of Metso and our company for working together as one to reach this outstanding result," says Wu Hanxing, GM, Shandong HengAn Paper Co. "This press unit provides high machine speed and continuous production due to no downtime, giving our corporation an even stronger position in the market."

HengAn also operates an Advantage ViscoNip press in the PM 8 line at its mill in Changde City, Hunan province, and in its PM 6 line at the Anhai mill in Fujian province. The Advantage ViscoNip press yields substantial savings in drying energy consumption. An Advantage DCT 200 tissue line such as the one HengAn operates at its Weifang mill means a saving in energy consumption corresponding to EUR 750,000 a year, the company says.

The ViscoNip pressure unit conforms to the shape of the yankee, and produces a uniform nip load over a very wide range of linear loads from 70 to160 kN/m. Compared with a rigid roll or metal shoe against the yankee, the Advantage ViscoNip press is flexible and accommodating. It delivers the pressure where it is needed, in a uniform manner. This press technology delivers a more uniform profile compared with a suction roll press and the higher sheet adhesion results in improved softness and bulk.

Three more Advantage ViscoNip press units will be started up during 2012 in China: at Fujian HengLi Paper PM 2 in Nanan City, at Xiamen Xinyang Paper PM 1 in Xiamen City, and at Garven Sanitary Products PM 1 in Fyzhou city, all three in Fujian province.
