[0010] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0011] See Figure 1 , Figure 2 A grading wheel structure comprises a grading blade body 1, a section of the grading wheel blade body 1 is provided with an end cover 2, the end cover 2 is hollowed out, a shaft sleeve 3 is provided on the end cover 2, the length of the shaft sleeve 3 is less than the length of the grading wheel blade body 1, the shaft sleeve 3, the end cover 2 and the grading wheel blade body 1 are integrally formed, and the raw material enters the internal cavity formed by the grading wheel blade body from the hollow end cover. Since the internal space formed by the grading wheel blade body is large, the raw material is more stably and fully processed in the grading wheel. The shaft sleeve, the end cover and the grading wheel blade body are integrally formed, which can well improve the stability of the grading wheel during operation and effectively improve the service life of the grading wheel.

[0012] The outer side 5 of the sleeve is in an inclined arc shape, which not only strengthens the strength of the sleeve, but also effectively prevents the material from sticking outside the sleeve, thereby ensuring the grading effect of the material.

[0013] A protrusion 4 is provided at the other end of the classifying wheel blade body 1, and the protrusion blocks the raw materials to ensure sufficient classification of the raw materials.

[0014] The inner side 5 of the protrusion is in an arc shape, which effectively prevents the material from sticking outside the shaft sleeve and ensures the grading effect of the material.

[0015] The protrusion 4 is integrally formed with the classifying wheel blade body 1, which reduces the production process and improves the production efficiency.

[0016] The shaft sleeve 3, the end cover 2 and the classifying wheel blade body 1 are integrally formed of alumina ceramics.

[0017] Beneficial effects of this utility model patent:

[0018] (1) The integrated structural design ensures higher overall stability and longer service life.

[0019] (2) High-purity alumina has excellent wear resistance, is not easy to pollute graded materials, and has a wide range of applications.

[0020] (3) It has stable chemical properties and is not easily corroded by chemical substances. It has reliable protection in some acidic or alkaline environments.

[0021] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
