VGD:-Variable Groove Design
SAS:- Small Angle Sector
As believed and understood by every papermaker that refining is the heart for good paper making. PARASON’s focus is always on the optimization of available refining resources. We seek, collect, and process data and bar design implications resulting in the 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.
Refiner plates work on the principle of scissors. The multiple resolution and number of bar crossings create millions of scissors edges. Refining takes place at the bar edges, hence it is essential to have a right angle bar edge during refining.
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 causes 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, the ‘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. Due consideration to properties of erosion, corrosion, wear resistance of refiner plates is taken care of.
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 the profitability of the mills.
Overhung plate designs with higher outer diameter, increase the capacity of the refiner & cutting edge length of the plate. Resulting in increased plate life and improved pulp quality with enhanced capacity.
There are three basic metallurgical properties required in any Refiner Discs
There must be a 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 a wide range of metallurgy to suit the refining of various applications.
Newly proposed bar designs go through intensive R & D focused on field requirements like throughput, plate life & energy savings with a commitment to customer satisfaction..
Parason refining solutions provide uniform and efficient fiber development with ultra low intensity refiner plates

The wear resistance is improved by the special treatment to transform all metastable microscopic phases into stable microscopic phases.
The wear resistance of the disc is improved without sacrificing the breakage resistance. This treatment is applicable for the Cast as well as Milled refiner plates & tackles of special metallurgy.
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.
PARASON Finedge Welded Bar refiner plates are manufactured using Special Casting & Robot Welding CNC technology to provide maximum uniformity in the refining zone. PARASON Finedge Welded Refiner Plates are Welded with special welding technology. The plates will wear uniformly over time with zero draft angle on the bar. With higher bar height and minimum bar width, the hydraulic uniformity is maintained for a longer time.
PARASON precision special cast, laser & welding manufacturing process minimizes groove width variations, which allows the finer bar to optimize low-intensity applications. Plate life is maximized due to the high bar height that is able to maintain with this technology.

PARASON Finedge Inlet Curved Bar refiner plates are manufactured using Special Casting & CNC technology to provide maximum uniformity in the refining zone.
PARASON Finedge Curved Bar refiner plates are specially cast in our own foundry to provide uniform hardness throughout. The plates will wear uniformly over time have a longer bar length. The flow of pulp follows the grooves between the results of the bar 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 the inlet enables them to function better as a pump. The half dams between sectors, further improve the pulp residence time resulting in improved refining.
