Growing battery retirements are increasing demand for cleaner black mass and higher-value metal recovery. Material liberation directly affects black mass purity and copper foil and aluminum foil quality. Crushing must detach electrode coatings while limiting excessive fines and metal loss. This article examines crushing stages, particle-size control, скрининг, разделение воздушного потока, магнитная сепарация, and commercial performance validation.
How Does a Liberation Circuit Match Black Mass and Metal Product Targets?
01 · Liberation CircuitMaterial liberation should follow product specifications, not the smallest achievable particle size. The circuit must release coatings while protecting copper foil, aluminum foil, сталь, и пластик. Поэтому, engineers should define impurity limits before selecting crushers, экраны, and separators. Юшуньсинь reference lines process 500 кг/ч или 1,000 кг/ч. Their listed powers reach 300 кВт и 349 кВт. Both configurations combine physical crushing, разделение воздушного потока, and vibrating screening. They recover black powder, медь, алюминий, и железные фракции.
Product Specifications Set Liberation Target
Product Specifications define the Liberation Target for each stream. Черная месса, медь, алюминий, steel and plastic need different purity limits and equipment responses.
Controlled Liberation Prevents Value Loss
Controlled Liberation avoids over-crushing and metal loss. Staged crushing, screening and separation improve black mass quality while reducing copper, aluminum and dust contamination.
Material Balance Confirms Performance
Material Balance tracks black mass, медь, алюминий, сталь, plastics and losses. Восстановление, purity and recirculation data verify liberation performance after testing.
How Should Feedstock Data Define the Crushing Solution?
02 · Crushing SolutionA crushing line should start with a feedstock map, not a fixed machine list. Формат батареи, химия, charge level, влага, and casing structure change the required pretreatment. Поэтому, two projects with equal capacity may need different shredders, экраны, and safety controls. Yushunxin reference lines cover 500 kg/h at 300 кВт и 1,000 kg/h at 349 кВт. Однако, final power and layout should follow representative material tests.

How Does a Staged Liberation Circuit Protect Copper and Aluminum Foils?
03 · Liberation CircuitIndustrial material liberation needs several controlled stages. A single aggressive crusher creates excess fines and lowers metal value. Yushunxin lines combine physical crushing, разделение воздушного потока, и вибрационное просеивание. Reference capacities include 500 кг/ч и 1,000 кг/ч.
Primary Shearing
Opens Cells Safely
Primary Shearing opens battery structures while reducing heat and metal powder. Low-speed control helps expose internal layers without excessive foil damage.
Secondary Liberation
Releases Electrode Coatings
Secondary Liberation separates electrode coatings from copper and aluminum foil. Proper speed, feed rate and residence time improve black mass quality.
Match Equipment
With Liberation Force
Liberation Force should match battery structure and output targets. Измельчение, crushing and milling require different forces to avoid metal pulverization and contamination.
Closed Return Loop
Improves Recovery
Closed Return Loop sends unliberated oversize back for further treatment. It reduces over-grinding, protects foils and stabilizes downstream separation.
How Does a Screening Circuit Route Black Mass and Metal Fractions?
04 · Screening Circuit
Screening should control the liberation circuit, rather than simply classify finished materials. Each deck should route fines, metal fractions, and oversized pieces toward different stages. Yushunxin’s reference lines combine crushing, разделение воздушного потока, and vibrating screening. They offer processing capacities of 500 кг/ч и 1,000 кг/ч.
Tested Cut Points Build Recovery Route
Tested Cut Points define particle routing and product quality. Material testing helps set screening sizes for black mass, медь, aluminum and plastic recovery.
Multi-Deck Screening Stabilizes Separation
Multi-Deck Screening creates stable particle ranges for downstream separation. Different decks reduce interference and improve black mass and metal recovery efficiency.
Anti-Blinding Design Protects Material Balance
Anti-Blinding Design prevents blockage from wet powder, films and fine wires. Stable screening improves recovery, reduces re-crushing and protects metal fractions.
How Does a Separation Circuit Route Each Liberated Battery Fraction?
05 · Liberated Battery FractionSuccessful separation starts with material behavior, not with a long equipment list. Engineers should narrow particle sizes before applying magnetic, расход воздуха, гравитация, or electrostatic forces. This sequence protects black mass purity and improves copper and aluminum quality. Yushunxin reference lines combine crushing, разделение воздушного потока, and vibrating screening. Available configurations cover 500 кг/ч и 1,000 кг/ч. Their reference power reaches 300 кВт и 349 кВт.
Remove Ferrous Contamination Before Fine Separation
Remove Ferrous Contamination before fine separation. Magnetic drums and suspended magnets reduce iron carryover and protect downstream screening and upgrading equipment.

How Should a Commercial Line Verify Liberation Performance Before Acceptance?
06 · Commercial LineCommercial acceptance must verify product quality and stable output. Engineers should test the complete line under continuous load. Peak crusher capacity alone cannot prove project performance.
Product Testing Confirms Liberation Quality
Product Testing evaluates Liberation Quality through residual coating, металлическое загрязнение, black mass carryover and ferrous content. These results verify separation performance.
Continuous Operation Proves Rated Capacity
Continuous Operation should verify throughput, product output, recirculation ratio and downtime. Actual capacity depends on battery type and impurity level.
PLC Controls And Feed Trials Confirm Stability
PLC Controls monitor current, температура, кислород, airflow and dust pressure. Feed Trials with different batteries verify stable operation and final product quality.
