Китайский завод по дроблению шлака: 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 миллионов тонн ежегодно, that means 150,000200,000 tons of slag requiring processing, хранилище, or disposal. Landfill disposal costs range from $1545 за тонну, перевод на $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
• Equipment downtime: Conventional crushers designed for virgin rock fail prematurely on abrasive slag, with wear part replacement every 24 недели
• Давление на соблюдение экологических требований: 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
• Нестабильное качество продукции: 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?

Обзор продукта: Китайский завод по дроблению шлака

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, вторичное дробление, metal separation, and screening in a single streamlined workflow.

Операционный рабочий процесс

1. Приготовление корма: Frontend loader or conveyor feeds raw slag (0800мм) into the vibrating feeder with grizzly bars, which removes fines under 50mm and ensures consistent feed rate
2. Первичное дробление: The jaw crusher reduces slag to 0150mm, with hydraulic adjustment to accommodate varying slag hardness and metal content
3. Разделение металлов: Overband magnetic separators extract ferrous metals (обычно 25% of feed weight) from the crushed material stream
4. Вторичное дробление: The cone crusher or impact crusher further reduces material to 040mm, with the crushing chamber configured for slag's specific fracture characteristics
5. Скрининг и классификация: Multideck vibrating screens separate material into commercial grades (05мм, 515мм, 1540мм) while returning oversize material to the secondary crusher
6. Окончательное восстановление металла: Secondary magnetic separation and eddy current systems capture remaining metallic content before stockpiling

Область применения

This plant processes aircooled blast furnace slag, украсть удар, and ferroalloy slag with feed sizes up to 800mm.

Часто задаваемые вопросы

What slag types can this plant process?

The China Slag Crusher Plant handles aircooled blast furnace slag, кислородная печь (конвертер) украсть удар, электродуговая печь (ЭДП) шлак, и ферросплавный шлак. 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. Кроме того, 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, средний срок окупаемости составляет 1218 месяцы. 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 месяцы.

Какие требования к электропитанию для установки??

Стандарт 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.

How long does installation and commissioning take?

The modular design allows installation in 46 weeks with a crew of 68 рабочие. This timeline assumes prepared foundations and available craneage. Commissioning and operator training typically require an additional 12 недели. Our installation team supervises the complete process and provides handson training for your operators.

What warranty and aftersales support do you provide?

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?

Да. The plant's feed hopper accepts material from frontend loaders, existing conveyor systems, или самосвалы. 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.
