China Yiyu Printing and Packaging Project
China Yiyu Printing and Packaging Co., Ltd
May 8, 2023-Meixin successfully provided a dryer fabric cleaning system for a high-strength corrugated paper machine owned by China Yiyu Printing and Packaging Co., Ltd. The paper machine has a paper width of 3200mm and operates at a speed of 600 meters per minute, primarily producing high-strength corrugated medium, linerboard, and kraft paper of 110-170 g/m². The PF·Clean intelligent dryer fabric cleaning system deployed by Meixin for this project has effectively improved the paper machine's drying efficiency, operational stability, and paper quality.
1. Dryer Fabric Cleaning:
Function：Meixin's PF·Clean intelligent dryer fabric cleaning system is equipped with high-efficiency cleaning heads installed in the wrap angle area between the dryer fabric and guide rolls, maintaining a reasonable gap from the fabric. High-pressure water nozzles spray the fabric surface at a specific angle to loosen and detach adhesive contaminants. Front and rear air knives assist by blowing off the contaminants, while a vacuum extraction system discharges them outside the paper machine. An external air knife thoroughly removes residual moisture after cleaning.
Benefits:
Online cleaning of dirty dryer fabric during normal production without shutdown
No chemical additives throughout the process, environmentally friendly and pollution-free
Improves and maintains dryer fabric permeability, significantly enhancing drying efficiency
Eliminates web breaks, grooves, marks, and holes caused by dirty dryer fabric
Reduces rewinder breaks caused by stickies-related paper defects
Improves production efficiency and paper machine running performance
Helps increase machine speed and extends dryer fabric service life
Leveraging the three core technical advantages of the PF·Clean intelligent dryer fabric cleaning system – "online cleaning, no shutdown required, and no chemical additives"-Meixin has established a clean, efficient, and stable dryer section operating environment for China Yiyu, fundamentally eliminating web breaks and paper defects caused by dirty dryer fabric, and laying a solid foundation for the high-quality production of high-strength corrugated paper.
