2500mm Corrugated Paper Machine Vacuum Couch Roller
The corrugated paper machine vacuum couch roller is the final dewatering device at the wet end of the paper forming section. This critical paper mill equipment removes water from the wet web through powerful vacuum suction, significantly increasing sheet dryness before the web enters the press section. The corrugated paper machine vacuum couch roller features a robust stainless steel shell with precision-drilled double-spiral holes that maximize water removal efficiency while maintaining gentle sheet handling.
A dual vacuum chamber design provides flexible dewatering control for different operating conditions. The corrugated paper machine vacuum couch roller is also equipped with a removable vacuum box for easy maintenance and inspection, a built-in cleaning spray pipe to prevent shell hole blockage, and an adjustable suction width from minimum to maximum to accommodate various paper grades. By installing a high-quality corrugated paper machine vacuum couch roller, paper mills achieve higher sheet dryness, reduced steam consumption in the dryer section, and improved overall production efficiency.
