Anhui Shanying Paper Industry Co., in the City of Ma'anshan in Anhui Province, China, has completed the installation of two new Valmet containerboard machines. Both machines, PM 5 and PM 6, were recently successfully started up.
The new PM 6 machine (photo) set its 24 hr. average machine speed record of 1,398 m/min 12 days after startup.
"The Valmet board machine is very well equipped and has first-class performance. Our startup has been very smooth. Valmet and Shanying have arranged targeted board machine training for the operators, which is also of great help to us," said Mr. Wang, production manager of Anhui Shanying PM 6.
"Making lightweight containerboard using gap forming technology is new for Chinese containerboard makers. The most efficient European containerboard lines, making high quality lightweight end products, utilize gap forming concepts with excellent results. Now Anhui Shanying has taken this step with Valmet's technology and we are very pleased to cooperate with this forward-looking company," said Mark Singler, director of process technology, Valmet.
Valmet's delivery of PM 6 included a complete 8.60-meter-wide (wire) containerboard machine from headbox to winder. The delivery also included machine clothing and a wide range of process systems. This kind of an extensive overall delivery package from the same supplier enabled the design of a highly energy-efficient production line.
The new PM 6 is equipped with gap forming technology, OptiFormer Gap, which enables a new, higher production speed category for lightweight, high quality containerboard making. The production line also includes two winders. PM 6 produces fluting and testliner grades in the basis weight range of 50-110 gsm and with a design production speed of 1,500 m/min.
Valmet's delivery for PM 5 included a complete boardmaking line from headbox to reel with chemical systems, winder, and roll handling equipment. The new PM 5 is equipped with three headboxes, multi-fourdrinier forming section, center roll-based press section, sizing with film application, and hard nip calender. The production line is completed with a two-drum winder. The delivery also included machine clothing and a wide range of process systems.
The new 7.92-m-wide (reel) PM 5 produces recycled testliner and kraft top liner grades in the basis weight range of 90 to 175 gsm. The design speed is 1,200 m/min.
Anhui Shanying Paper Industry Co. produces and distributes packaging paper products in China. It offers paper and cardboard cartons. The company was established in 1957.
