Grain Gravity De-stoner

  1 QSC-type blowing style De-stoner is to separate stone, clods by adjusting wind pressure, amplitude and other parameters. Larger proportion material stone will sink down and move bottom to up under the stress of vibration friction; while smaller proportion material moves up to bottom.

2 This machine is equipped with internal fans, so there is no need to install wind net system. The Fans  and vibration system both have their own motors, so they will not affect each other when adjusted.

 3 Vibration system’s motor has a transducer, which uses different frequencies for small particles of material (millet), medium materials (mung, soybean), and large granular materials (kidney beans, broad beans) to remove stones better.

Our tem attend various international proffessional exhibition and conference.
