New Sun Paper testliner machines in China collect savings and efficiency with Flash Mixing of additives


Sun Paper, one of the leading paper and board makers in China, successfully started up its two new testliner paperboard machines with an annual capacity of 800,000 metric tons at Zoucheng in China. The whole investment included two new production lines PM31 and PM32.

The PM31 is equipped with three ply former. The design speed is 1200m/min, basic weight 110-250g/m2. The main product is Linerboard. PM32 is equipped with a two layer headbox The production is mainly corrugated medium and kraftliner - the range of 90-140g/m2. The design speed is also 1200m/min.
With support from Wetend and other suppliers the project enables Sun Paper to achieve high production efficiency, significant cost savings. Wetend Technologies Ltd supplied total the (10) TrumpJet stations installed for the both production lines. Main goal of the mill to exploit TrumpJet Flash Mixing Reactor Technology was to cut down chemical cost and improve sustainability in savings of water, energy and the chemicals.

Water saving through TrumpJet systems is minimum 1 m3/ton per line. Water and energy saving in a project like this makes investment for TrumpJet Flash Mixing Reactor systems alone already profitable. Significant chemical savings are a great bonus for everything.
