Technical Field

[0001] The utility model relates to the technical field of grinding devices, and in particular to a two-stage grinding device for ultrafine zirconium silicate powder. Background Art

[0002] It is a high-quality, low-cost opacifier, which is widely used in the production of various building ceramics, sanitary ceramics, daily-use ceramics, first-class handicraft ceramics, etc. In the processing and production of ceramic glazes, it has a wide range of uses and a large amount of application. The reason why zirconium silicate is widely used in ceramic production is also because of its good chemical stability, so it is not affected by the ceramic firing atmosphere, and it can significantly improve the bonding performance of ceramic body glaze and increase the hardness of ceramic glaze. Zirconium silicate has also been further used in the production of color picture tubes in the television industry, emulsified glass and enamel glaze in the glass industry. Zirconium silicate has a high melting point of 2500 degrees Celsius, so it is also widely used in refractory materials, glass kiln zirconium ramming materials, castables, and spray coatings.

[0003] At present, in the production and processing of zirconium silicate ultrafine suction, ordinary grinders are usually used for grinding zirconium silicate. Due to the high specific gravity of zirconium silicate and the large particle size of the grinding material, the particle diameter of zirconium silicate is still large after grinding, which makes it impossible to meet the subsequent production requirements.
