The intra-assay circulation shaping spheroidizing system of the present invention has characteristics of simple structure and convenient operation, and is worthy of being promoted.

Description

technical field [0001] The invention relates to the technical field of lithium battery manufacturing equipment, in particular to a batch inner circulation shaping and spheroidizing system. Background technique [0002] In view of the comprehensive requirements of the lithium battery industry on the particle size, sphericity, and tap density of negative electrode materials, it is becoming increasingly strict. On this basis, a shaping and spheroidizing machine that can integrate the above indicators has been developed. Compared with similar equipment already on the market, there are several differences. [0003] Existing equipment, in order to improve the sphericity and tap density of the product, often use multiple or even more than ten devices in series to achieve a certain sphericity and tap density, the number of equipment is large, and the power consumption is large. , the yield rate is low, and the tap density is low. The main reason is that the residence time of the ma...
