Vacuum Suction Press Roll with 30-40mm Rubber Coating and 4mm Drilled Holes for Paper Machine
The vacuum chamber's primary function is to extract air from shell holes. Thinner roll shells made from high-strength metal significantly enhance press dehydration efficiency in vacuum suction press rolls.
The vacuum pressure roller features a 30-40mm thick rubber-coated shell, which provides:
- Uniform pressure distribution
- Reduced felt abrasion
- Increased press line pressure
Production experience demonstrates that smaller axial and circumferential hole spacing with increased hole quantity:
- Significantly improves dehydration effectiveness
- Effectively eliminates embossing phenomena
- Extends felt service life
Optimal vacuum suction press hole diameter (typically ~4mm) balances:
- Sufficient water removal capacity
- Roller structural integrity
- Minimized paper "shadow marks"
