Drum screen is an important pulp making equipment widely used in pulp making and pulp industry. It is mainly used for separating and screening impurities in pulp to ensure the quality of the final pulp produced. The advantages of drum screens lie in their efficient screening ability and relatively low energy consumption.

The working principle of a drum screen is to use the rotation of the cylinder and the aperture of the sieve to separate fine fibers and impurities, thereby obtaining purer pulp. The design of a drum screen usually includes a rotating cylinder with a mesh attached to the outside. The pulp enters through the cylinder and is screened during the rotation process. Through this process, qualified pulp will flow out while impurities will be left inside the cylinder.
