Lead-Acid Battery Recycling Plant
Capacity: 1-10 TPH
Acceptable Scrap: Car Battery, UPS Battery, Storage Battery etc
Final Material: Lead Grids, Plastic, Acid, Separators.
The battery recycling plant employs a proprietary mechanism process that effectively separates the lead and plastic components from lead-acid batteries. The lead produced by this process is of 97% purity. This eco-friendly method is a more sustainable alternative to traditional pollution-based processes, such as burning and chemical processing.
The battery recycling plant comprises a series of machinery and equipment, including a shredder, vibration screen, conveyor, granulators, washing tank, hopper, screw conveyor, and gravity separation table (shaking/shaker table), which collectively facilitate the recycling process from the inlet of waste batteries to the production of recycled lead.
Our company has developed an innovative waste lead-acid battery recycling system that employs a range of cutting-edge technologies. The process begins with the breaking and separation of lead batteries, followed by the separation of acid, lead paste, lead grids, and plastic. The battery is fed into a shredder via a conveyor belt, then undergoes granulators and a water power sorting system. This allows for the separation of plastic and lead grids and paste based on their density. The electrolyte in the battery, or waste acid, is then derived and recycled in the waste acid treatment system.

How are lead acid batteries recycled – the recycling process explained?
The recycling of lead acid batteries involves 2 main steps;
- Breaking & Separating
- Secondary lead refining
Breaking & SeparationThe first step, is referred to as battery breaking, and literally smash the batteries in a four shaft shredder and then extracting the component parts including lead paste, metallic plates and connectors, polypropylene and other plastics, and acid electrolyte into streams that are handled in the subsequent recycling steps.
The sulfuric acid can be converted to Sodium Sulfate which is commonly used in fertilisers and laundry detergents and the plastic polypropylene container is output as pellets for reuse in new battery containers and other plastic products.
Secondary lead refining
The lead, in the form of lead metal and paste, from the breaking and separation process, is refined in a secondary lead smelting process, that produces lead in bullion form.
Process Flow
- Battery conveyed by belt conveyor for Preliminary crushing（900×1050 4 shaft shredder）,the crushed lead particles, plastic particles, and lead mud will be sorted in the first step by the vibrating screen at the bottom of the shredder, and a part of the lead mud will be separated.
- Particles after the first crusher conveyed to the second crusher for smaller particles by screw conveyor.
- After the second crushing, the particles will enter the washing tank, and the light plastic will be sorted out here. The heavy lead particles and heavy plastic will sink to the bottom of the tank and be transported to the separation equipment by the screw conveyor for sorting.
- Difference in specific gravity between plastic and lead particles is used to separate the two materials with a shaking table to obtain lead particles and plastic particles without impurities.Lead particles can be smelted through a smelting furnace to make lead ingots, while plastic particles can be used for secondary use.
- In the process of crushing and sorting, the lead mud needs to be separated from water by a filter press, and then smelted together with lead particles to obtain lead ingots
- After you get the lead particles you can selling them to a Smelting company or you can build a melting plant by yourself ,we also supply the Advanced Rotary and Refining Furnaces.
MINGXIN RECYCLING design and manufacture various shredders and recycling machines, with custom recycling lines and solutions for processing plastic film, PET bottles, rubber tire, scrap metal, municipal solid waste, medical, chemical and industrial waste, etc.
