1. PAINPOINT DRIVEN OPENING

Managing slag is a persistent bottleneck with tangible costs. Are you facing these operational challenges?
High Disposal Costs & Liability: Landfill fees for untreated slag are escalating, and regulatory scrutiny on storage is increasing, creating both a financial and environmental liability.
Inefficient Material Recovery: Valuable metallic content trapped in slag represents lost revenue. Manual recovery is laborintensive and unsafe, while undersized crushers fail to liberate metal effectively.
Unplanned Downtime & Maintenance: Inappropriate crushers not built for abrasive slag suffer rapid wear on liners and components, leading to frequent stoppages for maintenance and parts replacement.
Inconsistent Feed & Throughput: Fluctuations in slag size and composition can choke or overload standard crushers, preventing your plant from achieving a steady, profitable processing rate.
Space & Mobility Constraints: Fixed, largescale crushing circuits are capitalintensive and inflexible, unsuitable for smaller sites or operations requiring relocation.

The central question is: how do you transform this problematic byproduct into a recoverable asset without introducing new operational headaches? A purposeengineered custom slag crusher plant provides the targeted solution.

2. PRODUCT OVERVIEW

A Custom Slag Crusher Plant is a semimobile or stationary crushing circuit specifically configured for the size reduction and liberation of metallurgical slag (blast furnace, steel furnace, copper, etc.). Its design prioritizes abrasion resistance, tramp metal tolerance, and reliable throughput of hard, abrasive materials.

Operational Workflow:
1. Feed & PreScreening: Runofpile slag is fed via loader or conveyor. An optional primary scalping screen removes fine fractions to bypass crushing.
2. Primary Size Reduction: A robust jaw crusher or impact breaker performs the initial crushing to reduce large lumps to a manageable size.
3. Metal Liberation & Separation: The crushed product is conveyed past a powerful overhead magnetic separator to extract liberated ferrous metal for recycling.
4. Secondary Crushing/Sizing: Material may pass through a secondary cone crusher or impactor to achieve the final product specification (e.g., aggregate for cement substitute, road base).
5. Stockpiling: Sized aggregate is conveyed to stockpiles; recovered metal is collected for sale.

Application Scope & Limitations:
Scope: Ideal for integrated steel mills, foundries, metal smelters, and independent slag processing yards. Effective on ferrous slags (blast furnace, BOF), nonferrous slags (copper, nickel), and certain industrial byproducts.
Limitations: Not designed for primary rock mining or extremely highvolume quarry applications exceeding ~150200 TPH continuously. Performance on slags with extremely high moisture content may require feed system modifications.
