Technical Field
[0001] The utility model relates to the technical field of grinding equipment, in particular to refractory material grinding and screening equipment for lithium carbonate production. Background Art
[0002] Refractory materials are specialized materials capable of long-term, stable operation in high-temperature environments. They typically exhibit high refractoriness, excellent thermal shock resistance, corrosion resistance, and high-temperature strength. Refractory materials are widely used in industries such as metallurgy, building materials, chemicals, and power generation, for example in the construction of high-temperature furnace linings, thermal equipment, and other refractory structures.
[0003] In order to improve the various properties of refractory materials, refractory materials are usually compounded with various refractory powders. Therefore, grinding equipment is required to grind and screen the refractory raw materials. Refractory raw material powder grinding refers to the process of physically processing the raw materials of refractory materials into fine powder. This process usually involves the use of specific grinding equipment to ensure that the final product has the appropriate particle size distribution and physical and chemical properties. There are many types of refractory raw materials, including bauxite, silica, magnesia, etc., which play an important role in high-temperature industrial applications such as steel smelting, cement production and glass manufacturing.
[0004] Refractory raw material powder grinding can be performed using a variety of equipment, including traditional roller mills and modern ultra-fine grinding equipment. Screening powders using vibrating screening mechanisms requires manual transport of coarse particles for reuse, and powders can easily spread and contaminate the work environment. Therefore, a grinding and screening device that can save labor costs and improve the work environment is needed. Utility Model Content
