Double Disc Refiner, a crucial component in pulp and paper production, plays a significant role in refining pulp to achieve the desired quality.
This article delves into the intricacies of double disc refining, exploring its history, working principle, applications, advantages, and much more.
Introduction to Double Disc Refiner
The double disc refiner is a mechanical device used in the pulp and paper industry for refining various types of pulp. It employs the principle of refining pulp by passing it through the narrow gap between two discs rotating in opposite directions.
The double disc refiner operation follows the process where the pulp is added through the input into the abrasive section of the double disc refiner machine. The refining discs are set in such a way that they rotate in opposite direction. There is a small gap between the discs where the pulp is pushed and refined in between the plates.
The refined pulp after fiber processing pushed out through an outlet pipe for further processing.
Components of Double Disc Refiner
- Discs
The discs are the central components of the double disc refiner, usually made of durable materials such as cast iron or stainless steel.
- Refining Zone
The refining zone is the space between the discs where the pulp undergoes refining. It is designed to optimize refining efficiency while minimizing energy consumption.
- Motor and Drive System
The motor and drive system provides the necessary power to rotate the discs at the desired speed, ensuring efficient refining.
Working Principle of Double Disc Refiner
Stock material is introduced into the abrasive section via an inlet pipe. Inside the abrasive section, the material undergoes a process of beating and refining. Once refined, it is pumped out of the abrasive section and directed into the shell. From there, it is discharged through an outlet pipe.
Advantages of Double Disc Refiner
- Enhanced pulp quality
- Increased production efficiency
- Versatility in refining different types of pulp
- Reduced energy consumption compared to other refining methods
