The circular swing screen is a highly efficient screening machine specially designed to meet the needs of manufacturers requiring high-volume, high-precision screening. The simplest form of screening involves using both eyes to observe while manually sifting with both hands. The circular swing screen is a mechanical simulation of this process, effectively replicating the principles of manual screening motion. It is suitable for all types of fine and ultra-fine powders and granular materials, particularly those that are difficult to handle.

1. The basic rotational motion is similar to manual screening. The eccentricity is adjustable from 25 to 40 mm, and the low-speed V-belt speed is adjustable from 120 to 360 rpm.
2. The dwell time for each product can be adjusted by altering the radial and angular orientation of the swing screen relative to the drive shaft axis.
3. This creates a three-dimensional rolling motion combining horizontal and vertical movements. Material is uniformly distributed across the entire screen surface from the centre to the outer edge, propagating axially in a spiral motion, thereby completing the screening process for fine particles.
4. Horizontal and vertical acceleration increases with particle movement, enabling particles close to the sieve aperture size are successfully separated.; larger particles are transported to the outlet, where flow is controlled by an adjustable guide device, which is another factor influencing material residence time.
5. This process is repeated between screening layers.
