AI Technical Summary
Existing sand and gravel screening machines are noisy and prone to damage when screening large-diameter gravel, making it difficult to achieve low-noise and durable screening.
The system employs a drive mechanism to rotate the screening drum, combined with a sliding screening component and a vibrating screening component. The rotation of the screening drum and the vibration of the sliding screen achieve low-noise screening of sand and gravel, avoiding large-diameter sand and gravel from impacting the screen.
It effectively reduces noise during the screening process, extends the service life of the screen, and improves screening efficiency.
