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"
