With the rapid iteration of new energy technologies, end-of-life power batteries, photovoltaic (PV) modules, and wind turbine blades have emerged as critical waste streams. Scrap steel crusher equipment—specifically upgraded for these novel feedstocks—plays a pivotal role in enabling their regeneration and sustainable reuse. Leveraging advanced crushing, sorting, and resource recovery technologies, such systems significantly advance the green, circular development of the new energy industry.
Key Upgrades of Scrap Steel Crushers for New Energy Waste:
• Multi-Stage Crushing System:
– Primary Crushing (Shear-Type): Handles bulky items like wind turbine blades.
– Secondary Crushing (Hammer/Impact-Type): Refines battery casings and PV modules into uniformly sized particles.
• Intelligent Sorting Technology:
– Magnetic Separation: Recovers ferrous metals (e.g., steel battery shells).
– Eddy Current Separation: Extracts non-ferrous metals (e.g., copper and aluminum foils).
– Optical Sorting: Identifies and separates plastics and glass (e.g., PV panel encapsulants and cover glass).
• Corrosion-Resistant Construction:
– Crusher chambers lined with high-manganese steel or tungsten carbide coatings to withstand aggressive electrolyte corrosion from spent batteries.
Integrated Recycling Workflow:
1. Pre-Treatment (Discharge):
– Residual charge is safely neutralized via saltwater immersion or dedicated discharge equipment.
2. Sequential Crushing and Disassembly:
– Stage 1: Shell tearing—mechanically opens battery enclosures.
– Stage 2: Core pulverization—releases electrode materials (cathodes/anodes), separators, and current collectors.
3. Sorting and Purification:
– Magnetic separation recovers steel casings.
– Eddy current separation isolates copper and aluminum.
– Froth flotation or hydrometallurgical processes recover high-purity lithium, cobalt, and nickel compounds.
4. Hazardous Substance Management:
– Electrolytes are collected under closed-loop conditions and treated via chemical neutralization or thermal decomposition.
– Polymeric separators (e.g., PP/PE) undergo controlled pyrolysis to generate syngas or liquid fuel.
Environmental and Economic Benefits:
By processing new energy waste through optimized scrap steel crushers, landfill dependency—and associated risks (e.g., heavy metal leaching from batteries)—is substantially reduced. Carbon emissions are lowered across the lifecycle, while recovered materials re-enter manufacturing supply chains, closing the loop. This transforms waste into valuable resources—establishing a fully integrated, high-value circular system for new energy components.
