usine de concassage de scories en Chine: Complete Processing Solution for Steel Mill Waste Recovery

The Hidden Cost of Slag Accumulation

Every ton of steel produced generates approximately 1520% slag byproduct. For a midsized steel mill producing 1 millions de tonnes par an, that means 150,000200,000 tons of slag requiring processing, stockage, or disposal. Landfill disposal costs range from $1545 per ton, traduire en $2.259 million in annual waste management expenses. Beyond direct disposal costs, unprocessed slag occupies valuable plant real estate, creates environmental compliance risks, and locks up recoverable metallic iron valued at $4060 per ton of slag.

Your current slag handling approach may be facing these operational challenges:

• Recoverable metal loss: Traditional processing methods leave 37% metallic iron in discarded slag, representing significant revenue leakage
• Temps d'arrêt de l'équipement: Conventional crushers designed for virgin rock fail prematurely on abrasive slag, with wear part replacement every 24 semaines
• Environmental compliance pressure: Increasingly stringent regulations on slag disposal and dust control are raising operational costs
• Space constraints: Accumulating slag stockpiles consume 510% of plant footprint that could serve production purposes
• Qualité des produits incohérente: Downstream cement and aggregate buyers reject slag products with inconsistent gradation or excessive metal content

Is your current slag processing solution maximizing metal recovery while meeting environmental standards? Can your existing equipment handle the abrasive nature of slag without excessive maintenance intervals?

Présentation du produit: usine de concassage de scories en Chine

The China Slag Crusher Plant is a complete, integrated processing system engineered specifically for steel mill slag recycling. This stationary or semimobile plant combines primary crushing, concassage secondaire, séparation des métaux, and screening in a single streamlined workflow.

Flux de travail opérationnel

1. Préparation des aliments: Frontend loader or conveyor feeds raw slag (0800mm) into the vibrating feeder with grizzly bars, which removes fines under 50mm and ensures consistent feed rate
2. Concassage primaire: The jaw crusher reduces slag to 0150mm, with hydraulic adjustment to accommodate varying slag hardness and metal content
3. Séparation des métaux: Overband magnetic separators extract ferrous metals (typiquement 25% of feed weight) from the crushed material stream
4. Concassage secondaire: The cone crusher or impact crusher further reduces material to 040mm, with the crushing chamber configured for slag's specific fracture characteristics
5. Dépistage et classification: Multideck vibrating screens separate material into commercial grades (05mm, 515mm, 1540mm) while returning oversize material to the secondary crusher
6. Récupération finale des métaux: Secondary magnetic separation and eddy current systems capture remaining metallic content before stockpiling

Champ d'application

This plant processes aircooled blast furnace slag, voler un coup, and ferroalloy slag with feed sizes up to 800mm. It is suitable for steel mills producing 500,0003 millions de tonnes par an, independent slag processing companies, and construction material producers integrating slag recycling. The system handles slag with compressive strength up to 350MPa and temperatures up to 200°C from hot slag cooling areas.

Limites: The plant is not designed for watergranulated slag (which requires different milling equipment) or slag containing significant refractory materials exceeding 10% du volume d'alimentation.

FAQ

What slag types can this plant process?

The China Slag Crusher Plant handles aircooled blast furnace slag, four à oxygène basique (BOF) voler un coup, four à arc électrique (AEP) scories, et scories de ferro-alliage. The system processes slag with compressive strength up to 350MPa and metallic content up to 10%. Watergranulated slag requires different milling equipment and is not suitable for this crushing plant.

How does the plant handle tramp metal and noncrushable materials?

The hydraulic overload protection system detects excessive crushing force and automatically opens the crusher setting to pass noncrushable objects. En plus, the magnetic separators remove most ferrous metal before it reaches the secondary crusher. Field data shows this system reduces blockage incidents by 70% compared to plants without such protection.

What is the expected payback period for a typical installation?

Based on installations across 40+ steel mills in China and Southeast Asia, la période de récupération moyenne est 1218 mois. This calculation includes metal recovery revenue, aggregate sales, avoided disposal costs, and reduced environmental compliance expenses. Plants processing more than 200,000 tons annually typically achieve payback in under 14 mois.

Quelles sont les exigences d'alimentation pour l'installation?

Une norme 150200 tph plant requires 350450kW of installed power at 380V/50Hz (or 460V/60Hz for North American installations). Site preparation includes a 630kVA transformer, grounding system, and distribution panel. The plant's PLC system includes softstarters to minimize peak current draw during equipment startup.

Combien de temps prennent l'installation et la mise en service?

The modular design allows installation in 46 semaines avec un équipage de 68 ouvriers. This timeline assumes prepared foundations and available craneage. Commissioning and operator training typically require an additional 12 semaines. Our installation team supervises the complete process and provides handson training for your operators.

Quelle garantie et quel service après-vente fournissez-vous?

All equipment carries a 24month warranty against manufacturing defects. Wear parts are excluded from warranty but are stocked at regional warehouses for 48hour delivery. The comprehensive service package includes quarterly inspections and performance benchmarking to ensure your plant maintains rated capacity and recovery rates.

Can the plant be integrated with existing slag handling equipment?

Oui. The plant's feed hopper accepts material from frontend loaders, existing conveyor systems, ou camions à benne basculante. Output conveyors can discharge to your existing stockpiling or loadout systems. Our engineering team conducts a site assessment to design the optimal interface between your current operations and the new plant, ensuring minimal disruption to existing workflows.
