PARASON Variable Rib Design refiner plates are manufactured using Special Casting & CNC technology to provide the maximum uniformity in the refining zone.

PARASON Variable Rib Design refiner plates are manufactured with special cast technology to provide uniform hardness throughout. The plates wear uniformly.
 

•  
  • Suitable for mixed furnish Refining.
  • Normally long fiber & short fiber need to refine separately with different bar patterns as per required SEL & CEL.
  • The VRD design is made to deal with mixed furnish
  • The peripheral velocity for long fiber zone is little lower than HW zone which is need for respective furnish.
  • The retention time for long fiber is higher than short fiber.
  • The rib height for long fibre zone is higher & smaller for short fiber zone to give desired  refining effect
  • This design ensures the minimum shortening or damage to the fiber which give better strength in the paper with higher breaking length.
  • There is base taper in the disc for better throughput & optimization of hydraulic capacity of disc.
  • SAS design offers close control over cutting angle of refiner disc.

• Inlet Coarse Bar Pattern
• Outlet Fine Bar Pattern
• Base Taper
• No Breaker bar
• SAS Design
• No Dam
• Inclined Parting Line Between 2 Zones

• High Fibrillation
• Power Saving /T/oSR
• High Throughput
• No Collar Formation
• Less Fiber Cuting
• No Plate Clashing
