Step 3: Start the air compressor (1207), and the compressed gas rushes out through the air hole 1 (1214) and the air hole 2 (1216). The gas impact at the upper and lower ends causes the steel slag after the first crushing to be suspended in the crushing cylinder (1201), and then starts the driving motor 1 (1205). The driving motor 1 (1205) drives the crushing blade (1215) to perform a second crushing on the suspended steel slag. After the second crushing, the steel slag with a qualified volume is discharged through the discharge hole (1202), and the unqualified part of the steel slag is continuously crushed until it is completely qualified.
