The aggregate is crushed in the crushing cylinder 5, and then the second motor 19 is driven to drive the rotating rod 20 and the protrusion 21 to rotate. The fixed block 18 and the second screening plate 17 are lifted up and dropped by the protrusion 21, so that the second screening plate 17 can achieve a vibration effect, and the aggregate is screened twice.
