Principle of grain cleaning and stone removal equipment

　　When harvesting, transporting and storing, grains are always mixed with various impurities, such as clods, pebbles, sand and grass; before grain processing, we need to clean by grain cleaning and stone removal equipment, otherwise, it will affect the final product quality, Damage human health, and even affect the performance of subsequent processing equipment.

　　According to different impurity designs, granular substances such as grains, beans and coffee are always mixed with clods and metals. To remove these impurities, we have designed different cleaning equipment such as rust remover, weed remover and iron remover. Now, let's introduce the grain cleaning and stone removal equipment.

　　Machines are used to remove sand and pebbles, and their common cleaning methods are sieving and gravity. The screening method removes sand and pebbles according to the shape, size and sieve opening of the sand and pebbles. Gravity press utilizes the different gravity between sand grains to remove impurities under continuous vibration or external force (such as wind, water and centrifugal force).

　　The gravity dust collector is composed of a screening part, a classification part, a stone removal part and a wind selection part, and has the dual function of classification and stone removal. It is a newly designed high-efficiency corn cleaning equipment, which is an ideal equipment for grain and corn fine and deep processing cleaning parts.
