Valmet supplies a forming section rebuild for Ajin P&P in Korea – introduces innovative Sleeve Roll technology

Valmet will supply a forming section rebuild introducing a novel Sleeve Roll technology to Ajin P&P’s Dalseong mill in Korea. The rebuild of the paper machine PM 3 targets production increase and improved end-product quality. The start-up of the rebuilt machine is scheduled for 2020.  

The orders are included in Valmet’s orders received of the second quarter 2019. The value of the orders will not be disclosed.

 “Ajin highly appreciates Valmet’s know-how and strong focus on customer-centric research and development. Valmet has been continuously providing new and innovative solutions to the market targeting for example improved energy, water and raw material efficiency. The Sleeve Roll is an excellent example of this,” says Dr. Jin-Doo Kim, Vice President of Ajin P&P.

The delivery for PM 3 will include modifications to forming section. The existing fourdrinier forming section will be rebuilt into OptiFormer Hybrid by adding a top forming unit that utilizes a novel and innovative Sleeve Roll technology. Sleeve Roll is a specially designed roll, which has a sleeve-like outer layer where dewatering pressure is created with a shoe. Because of Sleeve Roll, the top forming unit is vacuumless. This makes the technology especially suited for rebuilds as it enables unrivalled dewatering capacity and energy savings. All the rebuilt machinery will be automated with Valmet DNA Machine Control System.  

The 5,900 mm-wide (wire) PM 3 produces recycled fluting grades in the design speed of 1,300 m/min and a basis weight range of 90-120 g/m².
