Grain cleaning equipment combining air separation and specific gravity screening according to the difference of material size, weight or contour. This machine USES the positive pressure way, USES the airflow and the vibration friction to produce the material the synthesis action, the material which the proportion is large settles to the bottom layer, through the screen surface vibration friction to move upward, the material which the proportion is small by the airflow action is suspended in the material layer the surface to flow downward, in order to achieve the separation according to the proportion. It can effectively remove the impurities in materials, such as mildew and spoilage grains, worm-eaten grains, black powdery meal grains, chaff grains, large and small chaff, dust, etc.

1. The frame of the whole machine is made of high quality steel plate, which is rust-proof, strong and durable, extending the service life.

2. The feeding hopper is located under the machine, which is more convenient for feeding with the elevator; Simple operation of inlet and outlet baffle.

3, air separation, screening, specific gravity selection, multiple screening, higher precision.

4, suitable for a variety of materials, agriculture, animal husbandry, forest animal husbandry, seed industry and so on.

5, the whole machine has the characteristics of simple structure, flexible operation, low power consumption, smooth operation, strong applicability, etc., the user can choose to replace the screen and weight screening screen to screen different materials, so as to achieve simple classification and achieve a multi-purpose machine.
