1. PAINPOINT DRIVEN OPENING

Managing slag is a persistent bottleneck with tangible costs. Are you facing these operational challenges?
Unreliable Throughput: Inconsistent crusher performance creates pileup at the furnace or processing line, delaying upstream operations and impacting overall plant output.
Excessive Abrasion & Downtime: Standard equipment wears rapidly when processing highly abrasive slag, leading to frequent component replacement and unplanned maintenance stops that cost thousands per hour in lost processing time.
Poor Final Product Control: Inconsistent particle sizing and excessive fines fail to meet strict specifications for aggregate or further beneficiation, reducing the market value of your output.
High Operational Costs: The combined expenses of high energy consumption, frequent wear part changes, and laborintensive maintenance erode profit margins from your slag valorization stream.

The central question for plant managers is this: how do you achieve consistent, costeffective slag reduction with minimal operational disruption?

2. PRODUCT OVERVIEW

A modern slag crusher plant is a stationary or semimobile system engineered specifically for the primary and secondary crushing of metallurgical slag (blast furnace, steel furnace). It transforms large, irregular slag feed into a calibrated aggregate product for use in construction, road base, or as feedstock for further metal recovery.

Operational Workflow:
1. Feed & PreScreening: Runoffurnace slag is fed via loader or conveyor. An initial grizzly or scalping screen removes fine material bypassing the primary crusher.
2. Primary Reduction: A heavyduty jaw crusher or impact breaker reduces large slabs (often up to 11.5m) to manageable sizes (typically under 200250mm).
3. Secondary Crushing & Screening: A cone crusher or secondary impactor further refines the material. A closedcircuit system with a vibrating screen separates product into specified size fractions.
4. Stockpiling & Dispatch: Sized aggregates are conveyed to designated stockpiles for loadout or transfer to downstream processes.

Application Scope: Designed for ferrous (iron, steel) and nonferrous (copper, lead) slags. Effective on aircooled and granulated varieties.
Limitations: Not suitable for primary crushing of virgin rock at high volumes; feed should be free of excessive tramp metal beyond designed magnetic separation capabilities.
