[0023] In this embodiment, the steel shots to be sorted are put into the sorting box 1 from the feed pipe 11, and then fall into the screening drum 3. The blower 21 is started, and the blower 21 blows out the steel shots with smaller mass from the discharge port 13 for screening, while the steel shots with larger mass fall to the top of the partition block 4, and the partition block 4 is moved to the height of the first sieve hole 301. At the same time, the motor 41 drives the connecting rod 42 and the stirring rod 43 to rotate, and the stirring rod 43 stirs the steel shots on the top of the partition block 4, so that the smaller steel shots flow out from the first sieve hole 301, and then flow out from the discharge port 12 through the guide plate 15, and the steel shots are screened for the second time.
