The dynamic balancing speed of the 4650mm kraft paper machine reaches 500 m/min, while that of the reel drum is as high as 1,200 m/min, providing ample mechanical margin for stable, high-speed operation. The heaviest moving component weighs approximately 30 tons and measures about 8 meters in length, with full consideration given to ease of installation and maintenance. The 4650mm kraft paper machine exhibits an average cross-machine shrinkage rate of approximately 4.5% and a pulp recirculation rate of 10%, effectively controlling sheet shrinkage and fiber loss.
This 4650mm kraft paper machine features a two-level layout with a scientifically sound structural design, ensuring high space utilization and facilitating operation, maintenance, and production line configuration. This 4650mm kraft paper machine employs variable-frequency speed control to automatically match the optimal power output to varying basis weights (80–160 g/m², with a rated basis weight of 110 g/m²) and machine speeds, effectively reducing electricity consumption per ton of paper produced.
With its comprehensive performance—featuring a wide web width, high speed, high-precision dynamic balancing, and an AC variable-frequency sectional drive system—this kraft paper machine has become an ideal choice for many paper mills.
