QSC De-stoner with Suction Hood Elevator is desgined to separate stone, clod from grain seeds by adjusting wind pressure, amplitude and other parameter. 

Stone with large gravity will sink down, moving from bottom to up under stress of vibration friction; material with small gravity moves from up to bottom. With internal fans, no need to install wind net system, The fans and vibration system are equipped with different motors, noninterference adjustment; vibration part motor with a transducer, which uses different frequency for small particles of material (millet), medium materials (mung bean, soybean), large granular materials (kidney beans, broad beans) to achieve the best good effect to remove stone.
