Product Description
Paper Machine Grooved Press Roll Rubber Coated
Grooved Press Roll Basis Information
Compared with ordinary press rolls, the grooved press roll offers superior dewatering capabilities with lower linear pressure and increased rubber layer thickness. This design reduces the middle height of the roller, preventing uneven water content at the paper edges that can cause ribbed channels.
Key operational considerations:
Wet paper sheet and blanket should separate quickly at the press section outlet
Blanket must separate rapidly from the grooved roller to prevent moisture return
Grooves must be kept clean to prevent blocking
Proper water drainage from grooves is essential
Requires soft doctor blade to remove high-pressure water from grooves
Grooved Press Roll Function
The press section's primary function is mechanical dewatering of the fiber mat. Increasing dry content before the dryer section improves process efficiency and reduces energy costs, making effective dewatering crucial for cost-effective paper manufacturing.
Each paper machine requires individual analysis for optimal cover quality, hardness, and surface characteristics due to varying sheet structures and dewatering requirements.
Grooved Press Roll Optimization
Key optimization factors include:
Flow path length minimization for efficient dewatering
Surface quality combined with suction holes/blind-drilled holes/grooves arrangement
Clothing design for enhanced dewatering
The interplay between clothing, surface design, and conditioning must be optimized as a system. Custom groove geometries can significantly improve:
Blind hole drainage efficiency
Hydraulic pressure reduction
Marking minimization
Micro groove designs can shorten flow paths and homogenize pressure distribution, with open surface areas reaching 48% on suction press rolls and 42% on standard press rolls.
