Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, in particular to a crushing device for processing fused quartz. Background Art

[0002] The usage amount of fused quartz has been increasing in recent years. Especially, it has very good effects in the surface layer of silica sol shell molds, and has made great breakthroughs in the use and price ratio compared with zircon materials. It is an ideal engineering application material. The thermal conductivity of fused quartz is low, and its thermal expansion coefficient is almost the smallest among all refractory materials. Therefore, it has extremely high thermal shock stability. So, during the roasting and pouring processes, the fused quartz shell molds rarely crack due to sudden temperature changes. It is an ideal refractory material for investment casting. The production of fused quartz requires the use of a crushing device.

[0003] Although the existing crushing devices can crush raw materials, during the crushing process, the generated particles are of different sizes. Some larger particles cannot meet the production requirements, and the generated dust is also mixed in the particles and requires additional cleaning. Content of the Utility Model
