As believed and understood by every paper maker that refining is the heart for good paper making. PARASON’s focus is always on optimization of available refining resources.  We seek, collect, and process data and bar design implications resulting in implementation of long term improvements in the refining area.

Reduce Refining Energy Consumption with Low Effort Solutions

Improving refining energy efficiency should be a priority in every mill. It’s a win from every angle. With energy efficiency comes lower energy consumption, lower operating cost, and increased operational flexibility.

40″ DDR Disk

34″ DDR Disk

Overhung plate designs with higher outer diameter, increases the capacity of the refiner & cutting edge length of plate. Resulting incresed plate life and improved in pulp quality with enhanced capacity.

Metallurgy of Refiner disc

• There are three basic metallurgical properties required in any Refiner Discs.
• Corrosion resistance
• Wear resistance
• Breakage resistance
• There must be correct balance of these three properties.
• It is necessary to improve the toughness without sacrificing the wear resistance which is a great challenge
• Parason has developed wide range of metallurgy to suit refining of various applications

Newly proposed bar designs go through intensive R & D focused on field requirements like throughput, plate life & energy savings with commitment to customer satisfaction.

PARASON Variable Rib Design refiner plates are manufactured using special casting & CNC technology to attain the maximum uniformity in the refining zone by providing uniform hardness throughout the plates

PARASON Variable Rib Design refiner plates are manufactured with special cast technology to provide uniform hardness, throughout and the plates wear uniformly. Therefore, the plates wear uniformly over time.

• • Suitable for mixed furnish Refining.
  • Normally long fibers & short fibers 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 short fiber 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 gives better strength to 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.

Special Features:

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

Advantages:

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

Application & Salient Feature

PARASON Finedge Milled Bar refiner plates are manufactured using CNC technology to provide the maximum uniformity in the refining zone.

PARASON milled bars are casted in own foundry as a solid piece to provide uniform hardness throughout. The plates will wear uniformly over a time. The zero draft angle on the bars help in maintaining longer hydraulics.

The PARASON precision CNC Milling manufacturing process provides accurate groove width, which allows finer bar to optimize low intensity applications. Plate life is also maximized by re-milling which allows 2-3 life cycles.

Special Features

• Narrow bar width
• Bar width range up-wards.. 1.6mm, 2.0mm, 2.25mm, 2.5mm
• High Cutting Edge Length (CEL)
• Zero draft angle on the bar
• Long life (Re-milling possible)
• Special metallurgy (17-4 PH)

Benefits

• Low Specific Edge Load (SEL)
• Good fibrillation – consistent fiber treatment
• Constant throughput
• Suitable for Hardwood, TMP, Non-wood fibers (Cotton) & Recycle fiber

Application & Salient Features

PARASON Finedge Inlet Curved Bar refiner plates are manufactured using Special Casting & CNC technology to provide the maximum uniformity in the refining zone.

PARASON Finedge Curved Bar refiner plates are specially casted in own foundry to provide uniform hardness throughout. The plates will wear uniformly over a time have a longer bar length. The flow of pulp follows the grooves between the bars results in longer residence time. The result of Finedge Curved bars helps in more gentle refining action which continues over a longer time. Curving the refiner bars at inlet enables them to function better as a pump. The half dams between sectors, further improve the pulp residence time resulting into improved refining.

The PARASON precision special casting & CNC manufacturing process provides accurate groove width, which allows finer bar to optimize low intensity applications.

Special Features

• Longer pulp residence time
• High Cutting Edge Length (CEL)
• Finedge Curved bars function better as a Pump.
• Suitable for hardwood & recycled fiber
• Special metallurgy

Benefits

• Finedge Curved bars-more gentle refining action
• Low Specific Edge Load (SEL)
• Good fibrillation – consistent fiber treatment
• More throughput
• Suitable for hardwood & recycled fiber
