Stones of same sizes of wheat kernel are separated by the principal of gravity classification which connected with another aspiration line where are again separating light impurities from the wheat. Gravity grading Stoner is mainly used for wheat, rice, peanuts, corn, soybeans and other classification, to stone, can also be used to select seed. The machine has a graded gravel, mud to good performance, low energy consumption, no flying dust, low noise, convenient operation & repair.
