Jiangxi Mingxin Metallurgical Equipment Co., Ltd. is a high-tech enterprise specializing in the research and development of environmental protection equipment. Its lead-acid battery recycling machine has significant advantages in the field of waste battery resource utilization. The following analysis will be conducted from the aspects of technical characteristics, process flow, qualification certification, and market feedback:
1、 Core technology and equipment parameters
The technical principle adopts a fully mechanized crushing and sorting process, which efficiently separates the lead grid, lead paste, plastic shell, and electrolyte in lead-acid batteries through physical separation technology. The equipment integrates modules such as a four axis shredder, vibrating screen, and hydraulic sorting system, utilizing density differences to achieve precise material grading. For example, lead bars and plastics are separated by a gravity separation station, and lead mud is dehydrated by a filter press and melted together with lead particles, ultimately producing recycled lead ingots with a purity of 99%.
key parameters
Processing capacity: 0.5-5 tons/hour (customizable)
Recovery rate: Lead 96%, Plastic 98%
Lead purity: 99% (official website data), some process steps can reach 99.9%
Energy consumption level: adopting low-speed and high torque design, saving more than 20% energy compared to traditional processes
Environmental characteristics
The waste acid treatment system recovers sulfuric acid through neutralization reaction to achieve recycling
Closed operation reduces dust emissions and is equipped with exhaust gas purification devices to ensure compliance with emission standards
Closed loop management of water resources, with a water consumption of less than 0.3 cubic meters per ton of battery
2、 Production process flow
Preprocessing stage
Crushing and screening: After the battery is roughly crushed by a four axis shredder, lead particles and plastic fragments are separated by a vibrating screen
Hydraulic sorting: using density difference to further separate lead grid from plastic, light plastic floats on the water surface, and heavy lead grid settles
Material recycling stage
Lead mud treatment: After pressure filtration and dehydration, the lead paste is mixed with lead particles and enters the smelting furnace to produce regenerated lead ingots
Plastic Recycling: The cleaned plastic particles are processed into recycled plastic raw materials through a granulator, which can be used to manufacture battery casings, etc
By product processing
After neutralization and concentration, waste acid is converted into industrial sulfuric acid for reuse
The exhaust gas is treated by bag filter and ionic liquid absorption tower, with a sulfur capture rate of ≥ 99.5%
3、 Enterprise Qualification and Certification
Core Qualifications
Having a qualification certificate for the disposal of waste electrical and electronic products, meeting the national requirements for hazardous waste disposal
Through ISO9001 quality management system certification, the equipment manufacturing process strictly follows international standards
technical patent
Holding multiple patents related to battery recycling, such as the waste battery flattening device (patent number: CN219446237U) and the lithium battery electrolyte separation equipment (patent number: CN115178004B)
Lead acid battery recycling technology has been included in the "Application Guidelines for Energy saving Technology Products in the National Communication Industry", and the overall technology has reached the advanced level in China
industry recognition
Received titles such as "Jiangxi Province Specialized, Refined, Unique and New Small and Medium sized Enterprise" and "National Intellectual Property Advantage Enterprise"
Products such as mineral processing shaker have passed CE certification, demonstrating that their equipment manufacturing capabilities comply with international standards
4、 Market Applications and Cases
typical customer
Provided whole plant equipment for multiple domestic recycled lead enterprises, such as production lines capable of processing 20000 tons of batteries annually, which have been put into operation in Jiangxi, Guangdong and other places
Participate in bidding for government environmental protection projects, such as the 2025 Law Enforcement Monitoring Project of Ganzhou Ecological Environment Bureau
user feedback
The equipment has a high degree of automation, which can reduce manual intervention and lower labor intensity
Modular design facilitates maintenance, with key components having a lifespan of over 8000 hours
Some customers have reported that the initial investment is relatively high, but cost recovery can be achieved through resource recovery within 3-5 years
5、 Precautions and Risk Warning
Corporate Background
Jiangxi Mingxin Environmental Protection Equipment Co., Ltd., a subsidiary, has a judicial case (involving a dispute over the right to health in 2024) and needs to pay attention to its operational stability
The registered capital will decrease from 70 million to 16.8 million in 2024, which may affect the project's ability to fulfill its obligations
Technical adaptability
The device has certain requirements for battery types, and the process parameters need to be adjusted according to the actual material characteristics
It is recommended to conduct pilot testing before procurement to ensure that the processing effect meets expectations
Policy Compliance
It is necessary to establish a traceability system that complies with the Interim Measures for the Management of Lead Acid Battery Recycling and Utilization
Suggest synchronously applying for policy support such as "urban mineral" demonstration bases to reduce operating costs
VI. Summary
Jiangxi Mingxin's lead-acid battery recycling machine is at the forefront of the industry in terms of technological maturity, resource recovery rate, and environmental indicators, especially suitable for large-scale recycled lead enterprises. Its core advantages include fully mechanized processes, high-purity product output, and comprehensive qualification certification. However, users need to carefully evaluate the operational risks of their subsidiaries and complete technical validation before project implementation.
