Total Solution for Steel Slag Torting, Treatment and Resource Utilization

Total Solution for Steel Slag Sorting & Resource Utilization turns metallurgical waste into iron concentrate and construction materials.

This solution employs "Crushing - Grinding - Magnetic Separation" to recover metallic iron (recovery rate > 90%). The remaining tailings are processed into cement or road base, achieving 100% resource utilization and eliminating solid waste stockpiles.

Step 1: Crushing (Pre-treatment)

Goal: Reduce slag size to <25-60mm for grinding.

• Coarse Crushing: Jaw Crusher handles large slag lumps (< 500mm).
• Fine Crushing: Secondary Jaw or Cone Crusher reduces material to suitable feed size.
• Feeding: Vibrating Feeder ensures uniform flow.

Step 2: Grinding & Classification

Goal: Liberate iron particles from slag matrix.

• Grinding: Rod Mill is preferred over ball mills to avoid over-grinding brittle slag while effectively flattening ductile steel particles.
• Classification: Screens separate -5mm fines for magnetic separation. +5mm oversize returns to the mill.

Step 3: Magnetic Separation (Iron Recovery)

Goal: Recover metallic iron.

• Primary Separation: Wet Magnetic Separator (CTS series) recovers magnetic iron powder.
• Secondary Recovery: Magnetic Pulleys on conveyors recover any remaining iron from tailings.

Step 4: Tailings Resource Utilization

• Cement: Used as iron corrector or active admixture.
• Construction: Road base, concrete aggregate, permeable bricks.
• Benefit: Creates a second revenue stream beyond iron recovery.

Q1: Why use a Rod Mill instead of a Ball Mill?

A: Rod mills use line contact for grinding, which is better for selective crushing. They effectively break brittle slag while flattening ductile steel particles without over-grinding them into slime, improving recovery.

Q2: Can I just crush and sell the slag?

A: You can, but you lose the value of the iron. Our solution recovers the iron first (highest value), then processes the tailings, maximizing profit.

Q3: Is the process wet or dry?

A: We recommend a Wet Process (Rod Mill + Wet Magnetic Sep) as it produces cleaner concentrate and controls dust. However, water recycling systems are included to minimize consumption.
