Valmet will supply a forming section rebuild introducing novel Sleeve Roll technology to Ajin P&P’s Dalseong mill in Korea. The rebuild of the paper machine PM 3 will result in a production increase and improved end-product quality. The start-up of the rebuilt machine is scheduled for 2020.
The delivery for PM 3 will include modifications to the forming section. The existing fourdrinier forming section will be rebuilt into OptiFormer Hybrid by adding a top forming unit that utilises 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 improves dewatering capacity and results in energy savings. All the rebuilt machinery will be automated with Valmet DNA Machine Control System. The 5,900mm-wide (wire) PM 3 produces recycled fluting grades in the design speed of 1,300 m/min and a basis weight range of 90-12gsm.
