According to different grading requirements, the cylindrical sieve generally has a grading level of 1-4 sections from fine to coarse, and the materials are screened from the first section to the last section of the screen from fine to coarse, which is larger than the screen opening of the last section. The material is discharged from the discharge port.
Structural drawing of Rotary screen：
Cylinder rotary screening machine is composed of round or hexagonal cylinder, frame, funnel, reducer, drive motor and auxiliary structure. The materials to be classified are fed into the feed inlet of the rotary screen by the granulator, and after being pushed in by the inner screen cylinder, the semi-finished products can be divided into standard particles, large particles and fine particles through the screening of the inner and outer screens during the rotation process. Three levels to achieve various particle classification.
