As believed and understood by every paper maker that refining is the heart for good paper making. PARASON’s focus is always optimization of available refining resources. We seek and collect 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.
It makes a lot of sense that a refiner disc should have uniform wear properties. Normally the variation in the wear of the refiner plates, may be wavy serrated or flat type.
The wavy & serrated wear cause maximum fiber damage and multiple disadvantages of high power consumption, increased cost per tonne, load variations etc. PARASON has innovated the concept of `ERP’ that is Edge Retention Property during strenuous refining conditions, ‘ERP’ plate has flat wear.
Casting is done by using the latest technology to provide the best condition for the alloys in temperature, time, melting technique to determine the best suitable alloy. A due consideration to properties of erosion, corrosion, wear resistance of refiner plates is taken care of.
Refining plates works on the principle of scissors. The multiple resolution and number of bar crossings creates millions of scissors edges. Refining takes place at the bar edges, hence it is essential to have right angle bar edge during refining.
PARASON DISC with `ERP’ has shown improvement in the energy consumption with power saving from 6 KW / hr. to 22 KW / hr. in various applications grossly the power saved annually adds to profitability of the mills.

CURVED BAR DESIGN
FULL CIRCLE DESIGN
PARASON Finedge Welded Bar refiner plates are manufactured using Special Casting & Robot Welding, CNC technology to provide the maximum uniformity in the refining zone. PARASON Finedge Welded Refiner Plates are Welded with Special Welding Technology. The plates will wear uniformly over time, and with the zero draft angle on the bar, with higher Bar height, with minimum bar width, hydraulic uniformity is maintained longer.
The PARASON precision Special Cast, Laser & Welding, manufacturing process minimizes groove width variations, which allows finer bar to optimize low intensity applications. Plates life is maximized due to high bar height able to maintain in this technology.

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-miling which allows 2-3 life cycles.
Narrow bar width
PARASON Finedge Welded Bar refiner plates are manufactured using Special CNC technology with Robotic Welding, to provide the maximum uniformity in the refining zone. PARASON Finedge Welded Refiner Plates are cast in special metallurgy suitable for special welding technology with higher bar height low bar width.
The PARASON precision Special Cast, Laser & welding, manufacturing process minimizes groove width variations, which allows finer bar to optimize low intensity applications. Plate life is optimized due to higher bar height.
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 special cast in own foundry to provide uniform hardness throughout. The plates will wear uniformly over a time and having 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 continuous 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.
