A Battery Breaking and Separation Unit for Lead Recycling Plant is not just a crusher – it’s an integrated, automated line that frees clean lead grids, lead paste, polypropylene chips and PVC/PE separators from scrap batteries while draining and containing the sulfuric acid.
How a Battery Breaking and Separation Unit Works
A well-designed battery breaking and separation unit is built around three synchronized stages: crushing, sink-float separation, and component classification. Lead paste goes to desulfurization or smelting, your metallic grids go directly to refining, and your plastics are saleable.
1. Automated Battery Feeding & Draining
Scrap automotive, industrial and VRLA batteries enter the lead acid battery recycling line through a belt or vibrating feeder. During transport, any free-flowing acid is collected in an acid-proof sump, and the batteries are lightly washed to eliminate fugitive acid fumes.
2. Hammer Mill Battery Breaker
A heavy-duty hammer mill specifically designed as a lead battery crusher. Adjustable grate bars control the output fragment size – typically 20–40 mm – which is critical for the downstream sink-float hydro separation.
3. Hydro Separation & Sink-Float System
The crushed slurry of lead paste, grids, plastics and separator fragments enters a series of hydrodynamic classifiers and vibrating sieves:
Heavy fraction (lead grids & poles)
Sinks instantly and is conveyed to a dewatering shaker. The clean metallic lead fraction, now free of paste and plastic, is ready for melting or kettle refining.
Light fraction (PP & PE)
Polypropylene chips and separator pieces float and are skimmed off, washed and dried. With our multi-stage rinse, PP purity exceeds 97%, meeting the strict requirements of plastic recyclers.
Lead paste slurry
Fine paste particles suspended in water are pumped to a filter press. The clarified water returns to the hydro circuit. The compacted lead paste cake goes to desulfurization (if you operate a lead paste desulfurization step) or directly to the rotary furnace.
