1. PAINPOINT DRIVEN OPENING

Managing slag stockpiles is a persistent operational and financial drain. Are you facing these common challenges?
Unrecovered Metal Loss: Valuable ferrous and nonferrous metals trapped in slag represent direct revenue loss with every ton processed.
Inefficient Processing: Manual breaking or underpowered crushers lead to bottlenecks, limiting your plant’s overall throughput and creating storage headaches.
High Downtime & Maintenance: Frequent breakdowns from abrasive slag cause unplanned stoppages, escalating repair costs and labor hours.
Inconsistent Output Size: Poorly sized material complicates downstream handling, magnetic separation, and final product saleability.
Space & Liability Constraints: Growing slag yards consume valuable real estate and present longterm environmental management concerns.

How do you transform this liability into a controlled, profitable recovery stream while ensuring system reliability? The answer lies in a purposeengineered slag crusher plant.

2. PRODUCT OVERVIEW

A slag crusher plant is a stationary or semimobile processing system designed specifically for the size reduction and liberation of metallurgical slag (blast furnace, steel furnace, copper, etc.). Its primary function is to crush large slag lumps into uniform, graded aggregates to maximize metal recovery via magnetic or eddy current separation.

Operational Workflow:
1. Feed & PreScreening: Raw slag from stockpile is fed via loader; an initial grizzly screen removes fine material bypassing the primary crusher.
2. Primary Crushing: A heavyduty jaw crusher reduces large lumps (often up to 1000mm) to a manageable size (approx. 150200mm).
3. Secondary Crushing & Screening: A cone or impact crusher further reduces material, which is then screened to separate correctly sized product.
4. Metal Separation: Sized material passes over suspended magnets or an eddy current separator to extract ferrous and nonferrous metals.
5. Stockpiling: Cleaned aggregate is conveyed to stockpiles for sale or reuse; recovered metal is collected for recycling.

Application Scope & Limitations:
Scope: Ideal for integrated steel plants, foundries, smelters, and standalone metal recovery facilities processing blast furnace (BF) slag, steel slag (LD slag), and nonferrous slags.
Limitations: Not designed for primary rock mining or extremely highsilica content materials without specific liner configurations. Feed size must be controlled within crusher intake dimensions.

6. APPLICATION SCENARIOS

Integrated Steel Plant – Blast Furnace Slag Processing

Challenge: A major steel producer faced low metal recovery from old BF slag dumps using rented mobile equipment, leading to high perton costs and inconsistent output hampering aggregate sales.
Solution: Installation of a dedicated 200 TPH stationary slag crusher plant featuring a heavyduty jaw crusher, twostage screening, and dual magnetic separation stages.
Results: Achieved consistent metal recovery rate of over 96%. Produced certified aggregate for road construction. Payback period achieved in under 18 months through combined metal revenue and aggregate sales.

Copper Smelter – Reverberatory Furnace Slag
