Jiangsu Changfeng Paper Contracts PMP for Press Section Rebuild

PMP (Paper Machinery Producer), Poland, is continuing an active support of the Jiangsu Changfeng Paper’s (JCP) development by implementing State-of-the-Art technology. 

After a successful Rebuild of Jiangsu Changfeng Paper’s (China) PM 3, including three new Intelli-Jet V® hydraulic headboxes, an Intelli-Press® with an Intelli-Nip® Shoe Press, and a new Intelli-Sizer® Metering Size Press in 2014, PMP (Paper Machine Producer), Poland, has been awarded a contract to rebuild the press section of the company’s PM 2, including another new Intelli-Nip Shoe Press. 

Intelli-Nip Shoe Press technology provides a hybrid of energy saving solutions and paper properties, and has recently become a desired solution worldwide, according to PMP. Currently, PMP is executing four projects that include its shoe press solution—in the U.S., Mexico, Columbia, and China.  

This time, project goals for Jiangsu Changfeng Paper are focused on increasing the paper machine’s capacity, by increasing the operating speed from 700 to 850 m/min. Another target is to significantly improve quality parameters of the final product as well as machine runnability.

PM 2, with a reel trim of 4,860 mm, produces two-ply fluting grades. The shoe press technology will play a key role in the final success, bringing ultra-high dryness (expected dryness after press 50%). It is important to mention that 1% more dryness after the press brings 4% steam savings in the dryer section. The shoe press technology enables significant improvement of paper properties (especially bulk and bursting strength) and significantly supports runnability,  bringing extra production days.

PMP’s scope of delivery includes the Intelli-Nip Shoe Module (design nip load of 1,050 kN/m), a plain mating roll of 1,460 mm dia., PM auxiliaries systems such as hydraulic unit for the shoe press, PM controls and panels, and mechanical drives. Structural machine components will be designed for a design speed of 900 m/min. PMP will also be responsible for on-site services, including on-site erection, startup supervision, and training services.

The delivery is scheduled for the beginning of 2017, followed by erection at site and startup.

Jiangsu Changfeng Paper Co. is a producer of high strength corrugated base paper and testliner (3-ply, 90–220 gsm). It has more than 650 employees.
