Cone Crusher CS75: Efficient Solution for Slag Crushing Plants

Slag, a byproduct of metal smelting (e.g., steel, iron, or copper production), was once considered waste. Today, it’s a valuable resource in construction, road building, and cement manufacturing—thanks to its durability and strength. To unlock its potential, a reliable crushing solution is key, and the Cone Crusher CS75 stands out as a top choice for slag crushing plants. Let’s explore why.

What is Slag?

Slag forms when molten metal reacts with fluxes (like limestone) during smelting, separating impurities from the metal. There are two main types:

● Ferrous slag: From steel/iron production (e.g., blast furnace slag, steel slag).
● Non-ferrous slag: From copper, lead, or zinc smelting.

With a Mohs hardness of 4–6, slag is medium-hard and abrasive—ideal for recycling into aggregates. Crushed slag is used in:
● Concrete and asphalt mixes (enhances strength).
● Road bases and railway ballast (resists wear).
● Cement production (as a supplementary material).

Why Cone Crusher CS75 for Slag Crushing?

The Cone Crusher CS75 is engineered to handle slag’s unique properties (abrasiveness, varying particle sizes) with precision. Its key advantages include:

1. High Crushing Efficiency

The cone crusher CS75 features a hydraulically adjusted crushing chamber and a powerful 75kW motor, delivering a capacity of 50–180 TPH (tons per hour). Its optimized crushing action (compression between a rotating cone and fixed concave) breaks slag into uniform, cubical particles—critical for high-quality aggregate production.

2. Durability for Abrasive Slag

Slag’s abrasiveness can wear down equipment quickly. The CS75 addresses this with:
● High-chromium alloy concave and mantle (wear parts), extending service life by 30% compared to standard materials.
● Sealed bearing system to prevent slag dust from damaging internal components.

3. Versatile Output Sizes

By adjusting the discharge gap, the CS75 produces slag aggregates in sizes ranging from 5mm to 40mm—suitable for:
5–10mm: Concrete fines.
10–20mm: Asphalt mixes.
20–40mm: Road base materials.

Typical Slag Crushing Plant Configuration with CS75

A complete slag crushing line integrates the CS75 with complementary equipment for seamless processing:

● Feeding System: Vibrating feeder (e.g., GZD 850×3000) with a grizzly screen to remove fine slag dust and control feed rate, preventing overload.

● Primary Crushing: Jaw crusher (e.g., PE 600×900) reduces large slag lumps (up to 500mm) to 50–100mm, preparing them for the CS75.

● Secondary Crushing: Cone Crusher CS75: Refines the pre-crushed slag into target sizes (5–40mm) with high efficiency.

● Screening System: Vibrating screen (e.g., 3YK 1860) separates crushed slag into different grades. Oversized particles (>40mm) return to the CS75 for reprocessing.

● Dust Suppression: Pulse bag filter and water spray systems capture dust from crushing and screening, complying with environmental standards (e.g., EU emission limits of ≤50mg/m³).

● Conveying & Storage: Belt conveyors transport slag between stages, while stockpiles store finished aggregates for loading and delivery.

Benefits of Using CS75 in Slag Plants

● Cost Savings: Recycles slag into sellable aggregates, reducing waste disposal fees and raw material costs.
● Environmental Compliance: Efficient dust control and low noise operation make it suitable for plants near urban areas.
● Easy Maintenance: Hydraulic adjustment simplifies gap settings, and quick-access wear parts reduce downtime.

Conclusion

The Cone Crusher CS75 is a game-changer for slag crushing plants, combining efficiency, durability, and versatility to turn industrial waste into valuable resources. Whether processing steel slag for road construction or blast furnace slag for cement, it delivers consistent, high-quality aggregates—driving sustainability and profitability.
