Valmet to supply another containerboard-making line for Shanying

The new production line (PM 23) with a wide automation package follows the delivery of the previous OptiConcept M board machine (PM 21) announced in December 2017 and the three winders announced in February earlier this year. PM 23 is an 8,600 mm wide (wire) board machine and is designed to produce high-quality fluting grades. By increasing its fluting and testliner production capacity (PM 23 will output 1,200 tonnes daily), Shanying is aiming for bigger market shares. The start-up of PM 23 is scheduled for the end of year 2019.

“Compared to conventional production lines, both of the new production lines will be able to significantly reduce carbon emissions as well as energy consumption,” said Timo Saresvuo, senior sales manager at Valmet.

Valmet’s delivery for PM 23 will be quite similar to PM 21 including a high-speed OptiConcept M containerboard-making line from broke collection to reel. PM 23 producing fluting grades will include OptiFormer Gap former with shoe blade technology equipped with OptiFlo Gap headbox enabling high capacity at high speed, which is the key feature of efficient lightweight containerboard manufacturing. Former with shoe and blade technology gives good strength properties, uniform CD profiles and excellent board formation. 

The headbox and former are followed by OptiPress Center roll-based press section, OptiRun Single dryer section, OptiSizer Film sizer, OptiCalender hard nip calender, OptiReel Pope reel and OptiCart Stream parent roll cart with transfer rails. The delivery will also include related ventilation equipment, runnability components, Valmet DNA machine control and process control systems, and a Valmet IQ quality measurement system. The machine will be delivered with a Valmet fabrics package and an additional production support after takeover.
