This machine is mainly employed for initlal sekection of barley .And it can also be used for material cleaning in areas such as powder manufacturing , rice milling , feedstuff and foodstuff .Besides , it also can remove the impurities and ore with high efficienty .

Based on the different setting velocities of barley and impurities , the similar size with barley .The de-stoning procedure is omitted , therefore , the cost is reduced . The environmental dust is controlled efficiently in the process of de-impurity process to that the working environment is improved, meanwhile, during the cleaning procdss the barley has received water’s pre-soap which will contribute to the germination effect.
