[0002] Pigments need to be cleaned during production. Since they are in powder form, horizontal cyclone screens are often used to clean them. The screen of the horizontal cyclone screen is cylindrical and placed in the body. After the material passes through the spiral conveying system, it is mixed with the airflow and atomized into the mesh cylinder. The impeller blades in the mesh cylinder make the material simultaneously subjected to centrifugal force and cyclone propulsion force, thereby forcing the material to be ejected through the mesh and discharged from the fine material outlet. The material that cannot pass through the mesh is discharged from the coarse material outlet along the mesh cylinder wall.

[0003] The existing cyclone screen removes impurities from pigment powder by centrifugation. Due to the fine powder state of the pigment powder, some of the powder will adhere to the outside of the sieve cylinder when it comes into contact with the sieve cylinder, thereby causing the sieve cylinder to be blocked, affecting its impurity removal efficiency, and causing some of the powder to be incompletely screened and mixed with coarse impurities.
