The dust-laden airflow rotates at high speed within the cyclone dust collector. Under the influence of centrifugal force, dust particles are driven to the inner wall of the collector. Subsequently, gravity causes the dust to settle and discharge through the outlet.

The rotating airflow converges towards the center of the hopper, forming a secondary vortex that flows outward. This process effectively filters dust from the hopper dryer and reduces air pollution, achieving an efficiency of up to 80%.
