Start-up ahead of schedule
PM 40 started up shortly after PM 39, and the two projects were executed by the same installation and commissioning team. The close collaboration between Voith and Sun Paper (sunpapergroup.com) and considerate planning has led to PM 40’s ahead of schedule start-up. Impressive was that it only took 39 days from I/O test to paper rolled-out.
A transportation challenge was the MG cylinder, one of the key components of the MG paper machine, which has a diameter of up to 20 feet. Extensive surveys and analysis have been conducted to ensure its safe delivery and all equipment arrived sound and timely.
Combination of latest technologies
PM 40 contains Voith’s latest technologies, i.e. the headbox, carbon fiber breast roll with hydrodynamic bearings, innovative Nipcorect™ Fullflex roll, MG cylinder, hood equipment, and soft calender.
The Yankee cylinder gives the paper an exceptional smoothness, which is very important for further processing.
The Nipcorect™ Fullflex roll is used as a press roll at the Yankee cylinder and allows ideal line load distribution over the whole width.
Innovative calendering concept ensures the specialty papers’ final smoothness.
The PM concept has optimum CD profiles, excellent fiber orientation with ideal dewatering capacity, high efficiency, and best quality. With a paper width of 4,800 mm and a design speed of 800 m/min, PM 40 will produce MG paper with a basis weight range of 25-80 g/m².
MG paper developed for the future
While society is calling for less usage of plastic products because of environmental concerns, paper has become one of the best alternatives to replace plastic. Paper is recyclable, degradable and can be reused dozens of times. PM 40 will produce MG paper which is environmental-friendly and serves as a new trend in the transformation and upgrading of the packaging industry. With distinct in design and usage, PM 40 is a tailor-made machine concept in smart combination with a modular system and will achieve an efficient and stable paper production of green products.
