Parason manufactures Variable Rib Design Refiner Plates using special casting & CNC technology that provides maximum uniformity in the refining zone.
The special cast technology provides uniform hardness throughout the variable rib design refiner plates.
This helps the plates to wear uniformly.
This design of variable ribs ensures the minimum shortening or damage to the fiber which gives better strength in the paper with higher breaking length.
There is a base taper in the disc for better throughput & optimization of the hydraulic capacity of the disc.
The SAS design offers close control over the cutting angle of the refiner disc.
