1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Is your slag handling operation a persistent bottleneck and a source of hidden costs? Pour les directeurs d’usine et les entrepreneurs en ingénierie, the challenges of processing metallurgical slag are multifaceted. Are you contending with excessive downtime due to tramp metal damage and abrasive wear on crusher components? The cost of unscheduled maintenance and component replacement can exceed six figures annually. Are you struggling with inconsistent feed size from frontend loaders, leading to crusher choking, débit réduit, et gradation imprévisible du produit final? This variability directly impacts your bottom line by limiting sales opportunities for your aggregate. En outre, does the sheer abrasiveness of your material result in premature failure of standard equipment, forcing you into a costly cycle of repairs instead of profitable production? These operational hurdles demand a solution engineered not just to crush, but to endure and optimize. A premium slag crusher plant addresses these specific pain points directly.

2. APERÇU DU PRODUIT

A premium slag crusher plant is a heavyduty, stationary or semimobile crushing system specifically engineered for the primary, secondaire, and sometimes tertiary reduction of metallurgical slag (haut fourneau, four à acier, etc.). Its design prioritizes extreme durability, consistent output control, and operational reliability in highabrasion environments.

Flux de travail opérationnel:
1. Alimentation & Présélection: Slag is fed via excavator or loader into a robust vibrating grizzly feeder, which removes fine material (40mm) bypassing the primary crusher to increase efficiency.
2. Concassage primaire: Oversize material is directed to a primary jaw crusher or impactor built with special alloys to handle extreme abrasion and occasional tramp metal.
3. Concassage secondaire/tertiaire: Crushed material is conveyed to secondary cone or impact crushers for further size reduction to specified cubical aggregates.
4. Dimensionnement & Stockage: Final product is screened via multipledeck screens into precise fractions (par ex., 05mm, 510mm, 1020mm) and conveyed to designated stockpiles.

Champ d'application & Limites:
Portée: Idéal pour les aciéries intégrées, chantiers de traitement de scories autonomes, et producteurs de granulats spécialisés dans les sous-produits industriels. Effective for blast furnace (BFS) and steel slag.
Limites: Not designed for primary ore or quarry rock processing where abrasion characteristics differ significantly. Maximum input slab size is defined by the primary crusher opening; exceeding this causes blockages.
