Ultrasonic inspection sieve is a high-tech automatic fine powder grading equipment developed by engineers of Ruang company on the basis of RA-JYS200-G sieve, which is the most effective solution to the mesh blockage in the current laboratory when doing automatic fine powder sorting and screening. It can be widely used in laboratories in pharmaceutical, metallurgy, chemical industry, mineral processing, food and other industries, with the characteristics of high screening accuracy and non-clogging of meshes, which truly solves the problems of laboratory screening due to agglomeration, static electricity, strong adsorption and other laboratory screening problems, and is a major technological breakthrough in the domestic screening industry.
