[0002] An abrasive is a hard material used for grinding, polishing, cutting or other metal processing processes. Abrasives usually have high hardness and wear resistance, and can rub against the surface of the workpiece during the grinding process to remove materials or change the surface roughness. Abrasives have become an essential material for manufacturing every precision product.

[0028] Please refer to Figure 5 , as an implementation manner of the base 26: A base 26 is provided at the bottom of the grading box 2. A rubber shock-absorbing pad 27 is sleeved outside the base 26. A foam aluminum plate 28 is provided on the top of the rubber shock-absorbing pad 27. The grading box 2 is arranged on the foam aluminum plate 28. A plurality of chemical bolts 29 are provided on the rubber shock-absorbing pad 27. A rubber anti-slip pad 30 is provided at the bottom of the rubber shock-absorbing pad 27.

[0029] More specifically, through the rubber anti-slip pad 30, the friction between the base 26 and the ground is greatly enhanced. The chemical bolts 29 facilitate the fixation of the base 26 and the ground, and the chemical bolts 29 have the characteristics of strong anchoring force, convenient installation and flexible construction.

[0030] In summary, when the whole equipment is in use or operation: when classifying and screening abrasives, the abrasives are added to the screening frame 3 and the first screen 4, the rotation motor 8 is started, the rotation motor 8 drives the rotating disk 9 and the rotating protrusions 10 to rotate, the rotating protrusions 10 collide with the sliding protrusions 11 on the sliding rod 5 in sequence, the rotating protrusions 10 squeeze the sliding protrusions 11 and the sliding rod 5 to move, the screening frame 3 and the moving plate squeeze the return spring 21, and through the elastic return action of the return spring 21, the screening frame 3 is driven to move reciprocally, so as to slide and screen the abrasives on the screening frame 3 and the first screen 4, and the filtered abrasives fall onto the second screen 12 and the third screen 13. The screening apertures of the first screen 4, the second screen 12 and the third screen 13 decrease in sequence. The driving motor 14 is started, the driving motor 14 drives the cam 15 to rotate, the cam 15 squeezes the vibrating rod 17 in sequence, and through the vibrating rod 17 squeezing the second screen 12 and the third screen 13, it is convenient to vibrate the second screen 12 and the third screen 13 to screen the abrasives. The abrasives with different particle sizes are discharged through different discharge ports 25. By arranging the bellows cover 24, it is prevented that the abrasives enter the cam 15.
