This DESTONER operates on a combined principle of wind, vibration, and sieve—making it ideal for classifying and removing impurities from wheat, paddy, corn, and other grains. It effectively concentrates light impurities such as grass seeds and rye, while removing heavier contaminants like gravel and mud lumps. Featuring an extended sieve body, it offers increased screening area and significantly enhanced stone removal efficiency. The air-adjusting hood adopts a front-and-rear separation structure, allowing independent adjustment to meet specific user requirements.
