1,The machines sift based on aerodynamics, the surface speed difference of seed and impurities, adjusting the seed of the air current. As impurities are light, they are sucked into the ejection chamber, while seed is heavy and is transferred into a vibrating sift having passed through air sifting.

2).The vibrating is three layers sieves with four exits which eject large impurities, small impurities and seed respectively, The vibration screen used for separating seeds according different sizes.

2.Working principle of grain screening machine/ rice destoner:

This kind of grain sieving machine matched with different types of sieves could be used to clean all kinds of grains and beans, including wheat, corn, sorghum, peanuts soybean, sesame, rape seeds and other granular raw material from stone, dust, impurity or bad ones.

2).It could efficiently remove stones and other impurities from grain by vibrating and sieving. It also could grade various material according to size and weight, such as wheat, durum, corn,rye, beans, oats, buckwheat, millet, peanuts, soybean, rape seeds, sesame, sunflower seed, sorghum, lentils, cumin and paddy screening process. After processed by our machine,you could get different grades of raw material you want for further processing work.

3.Features of grain screening machine/ rice destoner:

Small volume, light weight, simple structure, convenient installation, easy maintenance;

1.Low noise, low consumption, high efficiency and low cost;

2.High accuracy of screening, no dust pollution, environmental protection.

3.Replaced variety of screen and long service life
