Ajin P&P takes a new leap in high-quality board production with the start-up of BM 2 with Sleeve roll technology

Sep 5, 2024

Beginning of September 2024 marks an important milestone for Ajin P&P's Hyunpoong mill in Korea. Their BM 2 was successfully started-up after rebuilding the two-ply forming section into an OptiFormer Multi by adding novel Sleeve roll technology with Valmet Sleeve Roll Belt to the combining position of the two plies. This was a repeat order from Ajin P&P for the Sleeve roll technology from Valmet, following the BM 3’s forming section rebuild in 2021.

“I have a high confidence on Valmet technologies and their project deliveries based on the long co-operation and history together. I was positive that we will succeed also in this BM 2 project. By systematical and hard work before and during shutdown, installation, and start-up we reached all common performance and safety targets. With Sleeve roll technology Ajin P&P can make a leap forward to produce even higher quality board.” Dr. Jin-Doo Kim, CEO of Ajin P&P.

Novel Sleeve roll technology in combining position

Sleeve roll is a forming section technology that creates extremely high dewatering pressure to the board web. The pressure increases flow rate out of the combined web and allows densification of the web. The densified web improves ply-bond strength, eliminates need for using wet end starch and allows high ash content to be used. This innovative technology redefines dewatering by harnessing the power of compression already in the forming section, reducing the need for energy-intensive vacuum methods that conventional forming technologies rely on.

The rebuilt machinery is automated with Valmet DNA Machine Control System.

The 4,650 mm-wide (wire) BM 2 produces test liner grades in the design speed of 1,000 m/min and a basis weight range of 115–250g/m².

Sleeve roll technology

The journey to innovate board and paper machine technology has led to the breakthrough known as Sleeve roll technology. This innovative technology redefines dewatering by harnessing the power of compression already in the forming section, reducing the need for energy-intensive vacuum methods that conventional forming technologies rely on.

Valmet receives a repeat order for a forming section rebuild with Sleeve roll technology from Ajin P&P in Korea

Valmet will supply a forming section rebuild with an innovative Sleeve roll technology and machine control system to Ajin P&P's Hyunpoong mill in Korea.

Rebuilding for better packaging

“A company that makes the world beautiful” with packaging – Ajin P&P’s slogan becomes even more true now that the company’s smart factory plan has just been approved by the Korean government.

Valmet's novel Sleeve roll technology awarded first prize at ATIP Innovation Contest

Valmet won this year's prestigious 'Palme d'Or' Innovation Award with its novel Sleeve roll technology and Valmet Sleeve Roll Belt. The award was given by the French Paper Industry Technical Association (ATIP). The innovation contest was arranged in connection with the ATIP Conference and Exhibition in Paris, France on December 8-9, 2022.
