[0002] New electrode materials, electrode systems and battery structure design have become key technologies in the development of lithium-ion batteries. Among them, phosphorus-carbon negative electrode materials, as one of the key materials for lithium batteries, are mainly used as lithium storage carriers to realize the embedding and de-embedding of lithium ions during charging and discharging. During their preparation process, the raw materials often need to be crushed to meet production needs.

[0003] The existing pulverizing and ball milling device for preparing phosphorus-carbon negative electrode materials generally directly puts the phosphorus-carbon negative electrode material to be processed into the pulverizing equipment for pulverization. After the pulverization is completed, it is secondary pulverized by the set ball mill equipment, and then the material is unloaded. Although the existing technology can complete the pulverizing and ball milling of phosphorus-carbon negative electrode materials, the position of the pulverizing roller of the pulverizing equipment used is relatively fixed, and it is difficult to adjust the position of the pulverizing roller according to materials of different sizes and specifications. The phosphorus-carbon negative electrode material is easy to get stuck in the pulverizing equipment. In addition, during the pulverizing process, a lot of dust is easily generated. If it is not handled, it is easy to threaten the operating environment and the health of the operators. Therefore, we urgently need a pulverizing and ball milling device for preparing phosphorus-carbon negative electrode materials to solve the above problems. Utility Model Content
