The arc screen in the pulp production industry is a key screening device in the pulp and paper making process, mainly used for pulp purification and coarse residue separation. The main components of the arc screen include the screen wire, the support frame and the spray device. By utilizing the impact of water flow and the mechanical separation effect of the screen wire, the separation of pulp and impurities is achieved.

Technical features of arc screens
1. High efficiency and energy saving: Unpowered design, extremely low operating cost, consuming only a small amount of energy of the pulp pump.
2. Simple structure and convenient maintenance: The equipment is composed of a few components such as a pulp feeding box, an arc screen plate and a casing, with a low failure rate and quick screen plate replacement.
3. High screening efficiency: The unique arc-shaped design keeps the pulp in close contact with the screen surface, ensuring high screen surface utilization and large unit area throughput capacity.
4. Gentle treatment of fibers: The static screening method exerts a small shear force on the fibers, which can effectively protect the fiber length and is beneficial to the strength of the paper.
5. Small floor space: Vertical installation, compact structure, and easy to arrange in the production line.
