1. PAINPOINT DRIVEN OPENING

Managing slag is a critical but costly bottleneck. Inefficient processing directly impacts your bottom line through equipment wear, production delays, and lost revenue from unrecovered metallics. Are you facing these persistent challenges?

High Abrasion Costs: Slag’s abrasive nature rapidly degrades standard crusher components, leading to frequent, unplanned downtime for liner changes and repairs, costing thousands in parts and lost throughput.
Inconsistent Feed & Bridging: Variable slag feed size and composition cause bridging in the crusher chamber, requiring manual intervention that halts your entire processing line and poses safety risks.
Metallic Recovery Inefficiency: Inadequate liberation of trapped metal from the slag matrix means valuable material is sent to waste, forfeiting significant potential revenue from scrap sales or recirculation.
Dust and Environmental Control: Dry crushing generates excessive dust, creating compliance issues with workplace safety (OSHA) and environmental regulations, leading to potential fines and operational shutdowns.
Unreliable Throughput: A crusher not engineered for slag’s specific hardness and density fails to maintain consistent tonnage, creating a backlog that delays site clearance and downstream operations.

The central question for plant managers is this: how do you achieve reliable, highvolume slag reduction with controlled operating costs and maximized metallic recovery?

2. PRODUCT OVERVIEW

An ISO Certified Slag Crusher Plant is a stationary or semimobile crushing system specifically engineered for the primary, secondary, or tertiary reduction of blast furnace (BF), steel furnace (BOF), or ladle slag. It transforms large, irregular slag chunks into precisely graded aggregate for sale or further processing.

Operational Workflow:
1. Feed & PreScreening: Runoffurnace slag is fed via loader into a hopper with a grizzly section to bypass subsize material.
2. Primary Crushing & Liberation: A heavyduty jaw or impact crusher applies controlled force to break down large slabs, effectively liberating embedded metallic pieces.
3. Metal Separation: Crushed material typically passes over an overhead magnetic separator to extract ferrous scrap before secondary crushing.
4. Secondary/Tertiary Crushing: A cone or impact crusher further reduces the material to the required product specification (e.g., 40mm aggregate).
5. Final Screening & Stockpiling: Vibrating screens classify the crushed slag into commercial grades for concrete additive, road base, or rail ballast.

Application Scope: Processing blast furnace (aircooled or granulated), steelmaking slag, and nonferrous slags from copper or nickel production.

Key Limitations: Not designed for primary ore crushing or extremely hard igneous rock. Maximum feed size is determined by the specific plant model and primary crusher inlet dimensions.
