Changzhou Zhengyuan Drying Engineering Co., Ltd.

Changzhou Zhengyuan Drying Engineering Co., Ltd. specializes in non-standard equipment for ternary cathode materials, including the novel structural design of ternary precursor reaction kettles (Patent No. 201911058181.2; Patent No. 201720272361.0), which ensures complete isolation from external atmosphere, reducing mechanical friction and maintenance costs. This design fully meets the production requirements for ternary precursors. The complex synthesis of ternary precursors is mainly achieved through co-precipitation reactions of salt solutions, alkali solutions, and ammonia water solutions using metering pumps in specific proportions. Throughout the process, the well-reacted slurry overflows from the reaction kettle, then undergoes filtration, washing, filtration, drying, mixing, demagnetization, and packaging to finally produce finished precursor materials. Currently, the high-quality positioning of ternary precursor products is set at physical indicators: Na < 100ppm; S < 1200p...
