Why Ordinary Crusher Fail in Slag Processing?
Processing steel slag or furnace slag is notoriously difficult. Many plant managers face the same frustrations: excessive wear on manganese parts, frequent downtime due to metal jamming, and failure to meet environmental dust standards. A standard stone crusher simply isn’t built for the thermo-mechanical stress of industrial by-products.
As a leading slag crusher manufacturer, Liming Heavy Industry has engineered a specific line of equipment designed to handle these challenges while maximizing the recovery of valuable metals.
Key Advantages of Liming Slag Crushing Technology
- Superior Wear Resistance: Our crusher utilize high-chromium and molybdenum alloy components, extending service life by 30-50% compared to traditional materials.
- Integrated Metal Separation: Designed to work seamlessly with magnetic separators, our systems ensure high-purity iron/steel recovery from the slag.
- Adjustable Particle Size: Whether you need aggregates for road construction or fine powder for cement additives, our small slag crusher and large-scale units offer precise control.
- Dust Suppression Systems: Built-in atomization sprays and sealed structures answer the critical question of how to reduce dust in slag crushing.
Technical Comparison: Choosing the Right Slag Crusher
Depending on your raw material size and hardness (Mohs hardness 6-8), we recommend the following configurations:
| Model Series | Type | Max Feed (mm) | Capacity (t/h) | Core Strength |
|---|---|---|---|---|
| PEW Series | Jaw Crusher | <1100 | 15-650 | Primary crushing, handles large slag cakes. |
| HST Series | Single-Cylinder Cone | <560 | 30-1050 | High hardness slag & metal liberation. |
| CI5X Series | Impact Crusher | <300 | 80-2000 | Excellent grain shape for slag aggregate. |
Global Success: 200TPH Steel Slag Recycling Project
Project Overview
A major metallurgical group in Southeast Asia required a solution to process 200 tons per hour of aged steel slag. The goal was to extract residual iron and produce high-quality slag fines for their cement plant.
Liming Solution
- Primary Stage: PEW860 European Jaw Crusher.
- Secondary Stage: HST250 Single-Cylinder Hydraulic Cone Crusher.
- Screening: S5X Series Vibrating Screen with magnetic pulleys.
Results
The client achieved a 98% metal recovery rate. The slag crusher price was offset within just 8 months of operation due to the high value of reclaimed scrap steel and reduced landfill costs.
Eco-Friendly Operation: How to Reduce Dust in Slag Crushing
Environmental compliance is no longer optional. To minimize the environmental footprint, Liming recommends a three-tier approach:
- Pre-wetting: Controlled moisture addition to the raw slag pile.
- Point-source Extraction: High-efficiency pulse dust collectors installed at discharge points.
- Enclosed Conveying: Using covered belt conveyors to prevent wind-blown fines.
