[0002] Waste circuit boards are a mixture of glass fiber reinforced resin and various metals. Waste circuit boards plus a large amount of scraps generated by the production of circuit boards need to be properly handled. Since most of the metal conductor materials on circuit boards are copper, generally after the circuit boards are damaged, the copper on the circuit boards will be crushed into copper powder for processing. Ball milling equipment is a commonly used grinding or grinding equipment to grind copper powder into the required powder.

[0003] For example, an ultrafine copper powder sorting and recovery device with authorization announcement number CN217646853U includes a screening box, wherein the inner cavity of the screening box is connected to multiple screening frames in sequence from top to bottom through short shaft rotation, and the screening frame is fixedly connected to a long shaft at one end away from the short shaft.
