1. PAINPOINT DRIVEN OPENING

Managing slag is a persistent bottleneck with tangible costs. Are you facing these operational challenges?
Unreliable Throughput: Inconsistent feed size and hard, abrasive slag cause frequent jams in standard crushers, leading to unplanned downtime that halts downstream processing.
Excessive Wear & Maintenance Costs: The abrasive nature of slag rapidly degrades standard manganese steel components, resulting in high spare part consumption and laborintensive changeouts every few months.
Inefficient Size Reduction: A singlestage crusher often fails to produce the optimal, uniform aggregate size required for highvalue applications like road base or cement additive, leaving revenue on the table.
High Operational Complexity: Plants frequently resort to a patchwork of primary and secondary units with complex material handling between them, increasing footprint, power draw, and points of failure.

What if your slag processing could achieve predictable throughput, lower costperton, and produce a consistently marketable product? The solution requires equipment engineered for this specific duty.

2. PRODUCT OVERVIEW

The Custom Slag Crusher Plant is a purposebuilt, semimobile or stationary processing system designed for the primary and secondary reduction of blast furnace (BF) slag, steel slag, and nonferrous slags. It transforms large, irregular slag feed (typically up to 800mm) into precisely calibrated aggregate (e.g., 05mm, 520mm, 2040mm).

Operational Workflow:
1. Feed & PreScreening: Runoffurnace slag is fed via excavator or loader onto a heavyduty grizzly feeder, which removes fine material (40mm) bypassing the crusher to increase efficiency.
2. Primary Crushing: Oversize material is directed into a robust primary jaw crusher configured for high abrasion resistance and large feed acceptance.
3. Secondary Crushing & Screening: The primary crushed material is conveyed to a secondary impactor or cone crusher for final size reduction, then onto a multideck vibrating screen for classification.
4. Product Stockpiling: Correctly sized aggregates are conveyed to separate stockpiles. Oversize material is recirculated back to the secondary crusher in a closed circuit.

Application Scope & Limitations:
Scope: Ideal for integrated steel plants, standalone slag processing yards, and construction material producers handling ferrous and nonferrous slags. Effective for producing road base, railway ballast, and raw feed for cement manufacturing.
Limitations: Not designed for primary rock mining or extremely high silicacontent materials without specific liner modifications. Feed must be free of excessive tramp metal; an overband magnet is recommended.

3. CORE FEATURES

HeavyDuty Grizzly Feeder | Technical Basis: Stepped grizzly bars with adjustable spacing | Operational Benefit: Removes fines prior to crushing, reducing crusher load and wear by up to 30% | ROI Impact: Directly extends wear part life and lowers specific power consumption (kWh/ton)

AbrasionResistant Primary Jaw Crusher | Technical Basis: Wedgesetting adjustment system & jaw plates in special chromium alloy steel | Operational Benefit: Maintains consistent discharge setting despite plate wear; plates last 23x longer than standard Mn18 | ROI Impact: Reduces downtime for jaw plate replacement and maintains product gradation stability

ClosedCircuit Secondary Crushing | Technical Basis: Secondary impactor with hydraulic adjustment and recirculating conveyor from final screen | Operational Benefit: Ensures precise control over topsize product specification; eliminates oversize contamination | ROI Impact: Enables production of premiumpriced specification aggregates with less waste

Centralized PLC Control System | Technical Basis: Automated process control with load management and fault diagnostics | Operational Benefit: Allows singleoperator oversight of entire plant; prevents crusher overloads automatically | ROI Impact: Lowers labor requirements and protects major components from damage due to feeding errors

Integrated Metal Recovery System | Technical Basis: Overband magnetic separator mounted on main discharge conveyor | Operational Benefit: Continuously extracts residual ferrous metal from the crushed stream for resale or recycling | ROI Impact: Creates an additional revenue stream while protecting downstream conveyors from metal damage
