The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0023] The present invention provides a grinding device, such as Figure 1-5As shown, the grinding device includes: a box body 1 and a top plate 2 mounted on the top of the box body 1, and a connecting plate 4 is detachably installed on the bottom of the top plate 2; a grinding mechanism arranged in the box body 1 for grinding silicon carbide; a screen 8 slidably arranged in the box body 1 for screening silicon carbide, and the screen 8 is located below the grinding mechanism and is arranged in an inclined state; a processing mechanism arranged in the box body 1 and below the screen 8 for secondary grinding of silicon carbide.
[0024] It should be noted that when silicon carbide is not ground sufficiently, the discharged material will have uneven particle sizes. Silicon carbide micropowder is mainly used in the abrasive industry, and there are special requirements for the classification of micropowders. Large particles cannot appear in the micropowders. Therefore, silicon carbide powder with uneven particle sizes is not conducive to use.

During grinding, the cylinder 7 is started to drive the screen 8 to slide, so that the screen 8 can screen the ground material to facilitate screening out larger particles of material.

[0032] In a further preferred embodiment of the utility model, the processing mechanism includes: an installation box 11 assembled in the processing box 9; a second grinding roller 12 rotatably mounted on the installation box 11 and adapted to the inner wall of the processing box 9; a second motor 13 arranged on one side of the box body 1, and the output shaft of the second motor 13 extends into the installation box 11; two bevel gears 14 fixedly mounted on the output shaft of the second motor 13 and the output rod of the second grinding roller 12, respectively, and the two bevel gears 14 are meshed with each other.
[0033] In this embodiment, when the screened material is discharged into the processing box 9 through the bellows, the second motor 13 is started, so that the output shaft of the second motor 13 drives the bevel gear 14 to rotate, and the bevel gear 14 drives the second grinding roller 12 to rotate, so that the second grinding roller 12 performs secondary grinding on the material, thereby ensuring the uniformity of the material grinding.

After that, the operator holds the first grinding roller 5 and removes the connecting plate 4 from the top plate 2, and then the first grinding roller 5 can be replaced, and the replacement is relatively quick.
