Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a graphite crushing and grinding device for lithium battery production. Background Technique

[0002] Due to the very active chemical properties of lithium metal in lithium batteries, the processing, storage, and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been applied for a long time. With the development of science and technology, graphite and other materials are usually used as the negative electrode materials of lithium batteries now. A graphite grinding device is a device used for grinding and dispersing graphite powder, and is widely used in fields such as batteries, coatings, and sealing materials. With the development of technology, graphite has received extensive attention due to its excellent electrical conductivity, high temperature resistance, and chemical stability. In order to meet market demand, the research and development and application of graphite grinding devices have developed rapidly. The existing graphite grinding machine grinds graphite raw materials by driving a rotating shaft through a motor. When the graphite particles are relatively large, the grinding time is relatively long, and it is also easy to be difficult to grind the graphite into the required particle size, resulting in poor grinding effect of the graphite and reducing the grinding efficiency of the graphite. For this reason, we have proposed a graphite crushing and grinding device for lithium battery production. Content of the Utility Model
