[0002] A circulating air separator is a device for separating solid particles, and its working principle is based on the principle of centrifugal force and gravity separation. Specifically, the circulating air separator produces rotational motion of gas fluid containing solid particles inside the device, and uses centrifugal force to push the solid particles to the outer wall and move downward, and finally falls into the dust collector at the bottom, while the clean gas is discharged from the top or side of the device. This device is widely used in grain cleaning process, and is especially suitable for removing light impurities in grain, such as light impurities and dust in wheat, corn and other granular products.
