Ultrasonic screening system is a kind of simple, practical and reliable screening system, which is the most effective solution to mesh clogging. It can be widely used in pharmaceutical, metallurgical, chemical, mineral processing, food and other industries that require fine screening and filtration. It has high screening and filtration precision and can effectively solve the screening problems such as agglomeration, static electricity and strong adsorption blocking mesh. It is a major technical breakthrough in the domestic screening industry.
