Knot Screen Basket for Pressure Screen

What is Knot Screen Basket?

A knot screen basket is installed in the rougher pressure screen and is commonly used to separate and remove larger foreign matter such as coarse fiber bundles and wood chips early in the pulping process. In addition, In the pulping process of plants such as reeds and bamboo, knot screen baskets with large and straight holes are usually used to remove plant nodes.

Knot Screen Basket Application

The knot screen basket is mainly used in the coarse screening system of the pulp and paper industry. Its function is to ensure that the pulp removes large volumes of undissolved fibrous substances in chemical pulping with minimal heat dissipation and black liquor loss. At the same time, it can also remove large non fibrous substances such as metal blocks and sand mixed in the coarse pulp, thus creating favorable conditions for subsequent washing, screening, and bleaching.
The knot screen basket is suitable for coarse screening of chemical pulping of fiber raw materials such as wood and grass, it has the advantages of high production efficiency, good removal effect, and stable and reliable equipment operation.

Advantages of the Knot Screen Basket

• Large aperture and high precision: Effectively intercepts larger harmful particles, allowing qualified pulp to pass through quickly.
• High strength: The screen drum is made of stainless steel and undergoes surface hardening treatment to withstand continuous friction.
• High processing capacity: Provides excellent pulp processing performance while maintaining high strength.
