The two second servo motors 14 drive the second connecting column 11 and the second crushing roller 12 to rotate respectively. The second bearing 10 ensures their stable operation. The crushing teeth 13 perform secondary fine crushing of the material to improve the uniformity of crushing. Then, the crushed material passes through the double-layer screening of the first filter screen 19 and the second filter screen 20 to intercept the coarse particles that do not meet the standards. The qualified material is drawn by the suction pump 22 through the suction pipe 23 at the bottom of the crushing box 1 and transported to the storage box 21 through the discharge pipe 24.
