1. Equipment Overview The lead-acid battery recycling and processing system independently developed by Jiangxi Mingxin adopts a process combining physical crushing and sorting with hydrometallurgy. The entire line includes core modules such as heavy-duty crushers, hydrocyclone separators, plastic separators, and lead paste conversion systems, achieving a processing capacity of 2-5 tons per hour and a metal recovery rate of over 98%. 2. Technical Highlights 1. Multi-stage crushing technology: Using a three-blade rotating crushing design and equipped with a liquid nitrogen cooling system, it effectively prevents the volatilization of heavy metals during the crushing process. 2. Intelligent sorting system: Through density separation and photoelectric sorting technology, it achieves accurate separation of plastics, metals, and separator materials (separation purity of 99%). 3. Environmental protection processing: Equipped with acid neutralization devices and exhaust gas treatment systems, the emission indicators meet the GB30484-2013 standard. 3. Operational Data According to 2021 test data: - About 680 kg of lead can be recycled from each ton of waste batteries - The recovery amount of polypropylene plastics reaches 120-150 kg - The recycling rate of wastewater reaches 85% - The failure rate of equipment during continuous operation is 0.5% 4. Maintenance Points It is recommended to carry out the following maintenance every 200 hours of operation: 1. Clean the carbon deposits on the crushing blades 2. Check the sealing parts of the hydrocyclone pumps 3. Calibrate the photoelectric sorting sensors 4. Update the neutralization reagent reserves This equipment is particularly suitable for recycling enterprises with an annual processing capacity of over 5,000 tons, and the investment payback period is about 18-24 months. In practice, it is recommended to pair it with an AGV material transport system to further enhance the automation level of the entire line.
