With the explosive growth of the new energy vehicle industry, the recycling and treatment of waste lithium batteries has become a key link in ensuring the sustainable development of the industrial chain. Jiangxi Mingxin Environmental Protection Equipment Co., Ltd., relying on its independently developed full-process crushing and recycling technology, has not only realized the regeneration of high-purity materials but also built an industrial closed loop with a win-win situation in environmental protection and economic benefits, setting a model of technological innovation for the industry.
Full-Process Technological Innovation to Address Industry Pain Points in Recycling
Jiangxi Mingxin's waste lithium battery recycling line adopts a multi-stage crushing and sorting process, realizing fully automated processing from battery disassembly to material purification through a combination of intelligent equipment. The core process includes: after the battery casings are disassembled by the primary crushing device, the hammer crusher performs secondary fine crushing to achieve sufficient dissociation of battery cores; subsequently, the grinder refines the materials, which are then roughly separated by the classifier screen and magnetic separator, and finally, the gravity separator is used to achieve precise separation of metals such as copper and aluminum from graphite powder. Throughout the process, a high-pressure blower maintains a negative pressure state, and a pulse dust collector is used to achieve zero dust emission, effectively solving the air pollution problem in traditional recycling processes.
The revolutionary breakthrough of this process lies in the application of the patented technology of "charged crushing + nitrogen protection". It enables direct crushing of batteries without long-term discharge pretreatment, greatly improving processing efficiency. At the same time, the inert gas environment completely eliminates the risk of fire and explosion during the crushing process. The subsequent supporting rapid electrolyte drying and separation equipment adopts a design of heat-conducting rotating shafts and inclined screens, which simultaneously completes the purification of black powder during the drying process, making the purity of graphite powder reach more than 99% and solving the industry problem of electrolyte residue affecting material reuse.
Three-Dimensional Value System Leading the Transformation of Green Manufacturing
In terms of environmental benefits, Jiangxi Mingxin's closed recycling system achieves full-process control of pollutants. Through a two-stage dust removal system integrating dust suction ports, water filtration, and high-efficiency filter plates, the dust collection rate reaches over 99.5%; the flue gas generated in the pyrolysis process is purified by a dedicated treatment system and discharged up to standard, with the risk of heavy metal leakage close to zero. Compared with primary mineral mining, this process can reduce carbon emissions by 85% when producing the same amount of lithium battery materials, significantly reducing the environmental footprint of the new energy industry.
The resource recycling value is particularly prominent. The entire set of equipment can achieve 100% recovery of metals such as copper and aluminum in lithium batteries, and the recovery rate of graphite powder is over 95%. Calculated based on an annual processing capacity of 100,000 tons of waste lithium batteries, approximately 8,000 tons of lithium carbonate and 12,000 tons of cobalt-nickel metals can be recovered, which is equivalent to reducing lithium ore mining by 500,000 tons, providing a sustainable solution to alleviate the shortage of strategic mineral resources in China.
In terms of economic benefits, the automated production line reduces the per-ton processing cost by 30%, and the price premium of high-purity recycled materials can reach 2,000-3,000 yuan per ton. In particular, through the precise separation of magnetic separation and gravity separation, copper foil and aluminum foil can be directly reused in the smelting process, eliminating the chemical purification cost of traditional hydrometallurgy and forming a "recycling-regeneration-remanufacturing" value closed loop.
Leading Standard-Setting to Promote the Standardized Development of the Industry
As a professional equipment supplier in the field of solid waste recycling, Jiangxi Mingxin's technical solutions cover various types of products such as flexible packaging batteries, mobile phone batteries, and cylindrical batteries. Its independently developed equipment, such as noise-reducing crushers and shock-absorbing drum screens, adopts vacuum sound insulation and elastic buffer design, controlling workshop noise below 85 decibels and significantly improving the working environment. These innovative practices are promoting the upgrading and improvement of industry standards.
With the in-depth implementation of policies such as the "Measures for the Management of Recycling and Utilization of Power Batteries for New Energy Vehicles", Jiangxi Mingxin's crushing and recycling technology provides a replicable standardized model for the industry. Its full-process data tracing system and environmental compliance design not only meet the current requirements of the "dual carbon" goals but also facilitate the national layout of the power battery recycling system through technology output, injecting lasting impetus into the green transformation of the new energy industry.
