2650mm Newsprint Paper Machine Solution

The 2650mm newsprint paper machine features a “crawl” speed of 25 m/min, which facilitates paper threading during startup as well as maintenance operations. It is designed for a maximum speed of 500 m/min, with an operating speed of 450 m/min and a dynamic balancing speed of 600 m/min; this tiered speed design ensures a substantial mechanical safety margin for routine operations. The 2650mm newsprint paper machine’s drive system utilizes an AC motor-based, variable-frequency sectional drive, allowing for independent speed adjustment of each section. This ensures stable tension as the paper web moves between the forming, pressing, and drying sections.

This 2650mm newsprint paper machine utilizes a top-wire former, which effectively improves the Z-directional structure of the paper sheet, reduces two-sidedness, and enhances both sheet uniformity and surface fineness—factors that are particularly critical for the smoothness of writing paper and the printability of newsprint. For the rolls used in this 2650mm newsprint paper machine, the journal ends undergo a quenching and tempering treatment prior to precision machining; furthermore, the tapered bearing seats on all rolls and cylinders are precision-ground to ensure a contact area of ​​over 90%.
