Why Is Rotary Drum Screen the Preferred Filter Element for Pulp Separation?

Paper remains an essential item in modern society. Filtration is vital in pulp processing systems as it needs to be able to remove unwanted impurities and particles to maintain product integrity and keep the system clean. However, the more filtration processes that are carried out in the pulp production process, the higher the cost of filtration. For this reason, the right filtration technologies and products are needed to solve the problem of high costs.

In pulp production, rotary drum screen in rotary screen machines plays an essential role in this process. Traditional filtration methods may lead to fiber and particles adhering together during the backwashing process, reducing filtration efficiency and increasing maintenance costs. The triangular cross-section design of the rotary screen drum provides excellent separation capabilities. Its inner and outer axial lines are designed to allow particles in the pulp to be efficiently separated from the fluid system. This special design ensures that fibers suspended on the wedge surface are less likely to adhere to other substances, thus achieving efficient separation and filtration. This advantage improves the efficiency of the pulp production process, reduces maintenance costs, and enhances product quality.

Design Advantages of Rotary Drum Screen

• Inner and outer axial wires. Inner and outer axial wires keep the surface of the rotary screen drum smooth and prevent fibers and particles from adhering.
• Prevent adhesion and entanglement. The wedge wire design prevents fibers and particles from adhering and entangling during backwashing.
• Axial motion scraper cleaning. Axial motion scraper easily clean the waste materials to maintain efficient separation.
• Backwash effectiveness. The rotary drum screen design ensures that fibers are quickly dislodged during backwashing, restoring efficient working conditions.

Rotary drum screen ensures product quality while helping to reduce production costs and improve resource utilization efficiency.
