In the pulp and paper production process, maintaining quality and efficiency is mandatory. One of the most essential pieces of equipment in achieving this goal is a pulp screening machine. These machines play a crucial role in delivering high quality pulp and obtain better efficiency.
The pulp screening machine delivers the pulp with good quality to the next stages of pulp production. But what exactly is a pulp screening machine and where are they used? Let’s find out in this blog.
What is a pulp screening machine?
A pulp screening machine is equipment used in the pulping process that is designed to remove unwanted impurities like knots, shives, and oversized particles from the pulp. With this separation of the contaminants, the pulp screening machine ensures the smooth flow of operation and improved quality of the pulp.
This quality of the pulp directly impacts the productivity and the final product quality. This also helps in reducing the operational costs of paper production.
Use of Pulp Screening Machine
Pulp screening machines are placed at various places in the pulping operation depending on the requirement of the stage of the process. At different stages, the pulp screening machine helps with the following uses:
- Removing contaminants: It helps in filtering out impurities such as plastic, sand, and metal particles from raw pulp.
- Refining pulp quality: By separating high-quality fibers from low-quality ones, screening ensures superior output.
- Reducing equipment wear: By eliminating impurities and foreign objects early in the process, these machines protect downstream equipment from damage.
The Positions of Pulp Screening Machines in Pulp Production Process
The pulp screening machines are strategically placed at various stages in the pulp production process and paper production process.
- Coarse Screening:
- This is the first stage of screening, where large impurities like plastics, sticks, and other foreign materials are removed. It prepares the pulp for finer screening later.
- Fine Screening:
- This stage focuses on removing smaller contaminants and improving fiber quality, ensuring a refined pulp for high-grade paper production.
- Approach Flow Screening:
- Before the pulp enters the paper machine, it undergoes approach flow screening to ensure it is free of contaminants that could disrupt the paper formation process.
- Fractionation Screening:
- Fractionation separates fibers based on size and properties to meet specific paper quality requirements.
Types of Pulp Screening Machines
The pulp screening machines are manufactured in various types depending on the places where they are placed in the pulp production process and each caters to different screening needs.
- Pressure Screens:
- These are enclosed systems used in both coarse and fine screening stages
- Vibrating Screens:
- Commonly used in coarse screening, vibrating screens separate contaminants using oscillatory motion.
- Drum Screens:
- These cylindrical machines are used for coarse screening and are effective in handling high-capacity flows.
- Centrifugal Screens:
- Ideal for removing lightweight impurities, these machines use centrifugal force to separate contaminants
