In the pulping process, the drum screen is a crucial screening and purification step, mainly used to separate qualified fibers from undistilled components, fiber bundles, sand particles and other impurities in the pulp.

The working characteristics of the drum screen are continuous and stable, with a large processing capacity. It can effectively improve the uniformity of the pulp and protect subsequent precision equipment (such as pulp sieves and desanders) from damage by large impurities. It is an important pretreatment device to ensure the quality of the pulp.
During the pulping process, the working principle of the drum screen is to rely on its rotation to drive the material to run along the screen cylinder. Meanwhile, the rolling and stirring inside the screen stratify the pulp, allowing smaller particles and fibers to fully pass through the screen wire, while larger particles and impurities remain in the screen cylinder and are eventually slowly discharged along the slope of the screen cylinder. This process plays a crucial role in the pulping production line, especially in the recycling of waste paper and the purification of raw materials. As waste paper usually contains impurities such as plastics and metals that cannot be utilized, the use of drum screens can effectively enhance the recovery and purification rate of raw materials.
