Why ultra-low intensity

Better plates, better pulp

Finebar refiner plates represented a breakthrough in low-consistency refiner technology when they were first introduced almost 20 years ago – and through continuous R&D, they continue to make breakthroughs today.

Manufactured using a patented technology, Finebar plates offer major advantages over plates produced by traditional casting, welding, or milling.  They are precision laser-cut, assembled, and diffusion-bonded – which produces very fine patterns with exceptional strength and durability. Ultra-low refining intensities are achieved with bar widths as fine as 1 mm.  The combination of narrow, high-strength bars and rectangular grooves results in a greater hydraulic capacity than conventional plates.

This unique and constantly evolving manufacturing technique is optimum for all fiber types and available for any low consistency disc refiner.  Finebar patterns are tailor-made for each customer application to achieve specific mill goals, including:

  • Pulp quality improvement
  • Reduced energy consumption
  • Longer plate life

Breakthrough technology

Mini Segment

Finebar manufacturing advantages:

  • Ultra low refining intensity:  With bar widths as narrow as 1 mm, Finebar has brought low intensity refining down to new target levels for short fiber pulp - as low as 0.1 Ws/m for optimum quality development, energy efficiency and plate life.
  • Reduced periphery plates:  When achieving the lowest possible refining intensity is not necessary, reducing the active plate diameter is an option to minimize the no load power consumption of the refiner and save on annual energy costs - as long as the proper refining intensity and hydraulic capacity of the plates are maintained. Finebar Reduced Periphery plates can do just that.  By concentrating more bars within a smaller diameter refining zone and maintaining groove volume, significant power savings can be realized without impacting quality or process flow requirements.
