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 Filling Offers

- Design to suit fiber cement industry needs (pulping / refining)
- Available from 12′ to 64′ size and 25 HP to 8000 HP power loading.
- Ensures right alloy (stainless steel alloys).
- Excellently cast, machined and finished disc.
- Power saving from 6 KW – 22KW / hrs.Enhanced plate life.
- Uniform process results.

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.

SCISSOR Action
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.

IMPROVED ENERGY EFFICIENCY
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.Parason Segmental Refiner Disc 34“, 40“, 42“ & 48“DDR
Overhung plate designs with higher outer diameter, increases the capacity of the refiner & cutting edges of plate.Resulting incresedplate life and improved 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 scarifying the wear resistance which is a great challenge
- Parason have developed wide range of metallurgy to suit refining various applications.
New proposed bar designs go through intensive R & D focused on field requirement like throughput, plate life & energy savings with commitment to customer satisfaction.Welded Plate Manufacturing Methods

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 Plates (VRD)

- Suitable for mixed furnish Refining.
- Normally long fiber & short fiber 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 HW 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 give better strength in the 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
