The setting of the feeding mechanism 3 can reduce the impact force of the stone on the first crushing mechanism 2 when entering, thereby extending the service life of the equipment. After the stone is roughly crushed by the first crushing mechanism 2, it falls into the second crushing mechanism 4, and is finely crushed by the second crushing mechanism 4. The crushed stone falls into the screening frame 5. The screening frame 5 is driven by the vibrator 51, and cooperates with the damper 52 and the spring The spring 53 causes the screening frame 5 to vibrate under the second crushing mechanism 4 to screen the crushed stones.
