Advanced ERP technology refiner fillings available in sizes 12" to 64", engineered for superior fiber development with optimized bar geometry and metallurgy.
Parason manufactures a complete range of refiner fillings for the pulp and paper industry, covering both pulping and refining applications. Each filling is precision-engineered in Parason's own foundry with advanced casting, heat treatment, and CNC machining to deliver superior fibre development, energy efficiency, and extended service life.
Refining plates work 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.
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 and serrated wear causes maximum fibre 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 Excellence: 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.
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.

Overhung plate designs with higher outer diameter increases the capacity of the refiner and cutting edge length of plate.
Resulting increased plate life and improved in pulp quality with enhanced capacity.
Every refiner disc requires the right balance of three critical metallurgical properties — corrosion resistance, wear resistance, and breakage resistance. Improving toughness without sacrificing wear resistance is a significant engineering challenge.
Parason has developed a wide range of proprietary alloys optimized for specific refining applications, ensuring each disc delivers maximum performance and service life in demanding mill environments.
R&D Focus: Every new bar design undergoes intensive research and development focused on field requirements — throughput, plate life, and energy savings — with a commitment to customer satisfaction.
