Process flow: air separation (primary) - Screening - air separation (secondary) - gravity selection. Meet the requirements of grain granular material impurity removal specification.
Air separation part: use the aerodynamic characteristics to remove dust and light impurities, adopt the front and back double suction duct structure, convenient air volume control, with spiral settling chamber.
Screening part: plane vibration cleaning screen to remove large and small impurities, two-layer screen structure. It is equipped with rubber ball screen cleaning mechanism to prevent screen hole from blocking. The vibration motor is used as the source. The magnitude and direction angle of vibration can be adjusted, and the frequency is 960 times / min. The machine features high reliability and long service life.
Gravity separation part: positive pressure type gravity table, in accordance with the density separation principle to remove the less light impurities such as not full, sprouted grain, mildew, disease, moth eaten grain, etc.
