[0002] Zirconia is a ceramic material with the characteristics of high hardness, high melting point, high resistivity, high refractive index and low thermal expansion coefficient. It is widely used in wear-resistant ceramics, refractory materials, machinery, electronics, optics, aerospace, biology, chemistry and other fields. In practical applications, zirconia is often used to make artificial drills, dental implants, etc. At the same time, due to its special conductivity, zirconia can also be used as a material for electronic devices in high temperature environments. Therefore, a zirconia powder screening machine is urgently needed in the market.

[0003] However, the prior art still has the following problems:

[0004] First, during the synthesis process of zirconium oxide, crystalline powder is produced, which needs to be separated by screening. However, most of the existing screening devices are screened by hand with screening tools, and the degree of automation is not high. Due to excessive dust generated during the screening process, it is very easy to affect the breathing safety of workers.

[0005] Secondly, most of the existing zirconia powder screening machines are only equipped with one layer of screen. When zirconia of different sizes is needed, the screen needs to be replaced manually, which affects work efficiency. In addition, only one layer of screen cannot perform more detailed screening, which affects subsequent production.

[0006] In view of the above problems, the inventors proposed a zirconium oxide powder screening machine to solve the above problems. Utility Model Content
