Technical Field

[0001] The utility model relates to the technical field of tin powder processing, in particular to a tin powder screener capable of classifying and discharging tin powder particles of various specifications. Background Art

[0002] Tin is one of the most highly developed and utilized nonferrous metals in my country, widely used in industries such as metallurgy, electronics, electrical appliances, chemicals, building materials, machinery, and food packaging. With the nationwide trend toward lead-free, electronics manufacturers will increasingly incorporate tin powder into their products. Furthermore, with growing environmental awareness, solder powder's non-toxic and environmentally friendly properties will ensure its continued application in packaging for pharmaceuticals, electronics, chemicals, light industry, food, healthcare, and art supplies. The importance of solder powder is becoming increasingly apparent.
