1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Managing slag is a critical yet costly bottleneck in modern metal production and recycling. Inefficient processing directly impacts your bottom line through equipment wear, lost revenue from unrecovered metallics, and escalating disposal costs. Êtes-vous confronté à ces défis persistants?

Coûts d’abrasion élevés: The extreme abrasiveness of slag rapidly degrades standard crusher components, leading to frequent downtime for liner changes and rotor repairs, costing thousands in parts and lost processing hours.
Metallics Recovery Inefficiency: Ineffective liberation of trapped metal beads from the slag matrix means valuable material is sent to waste, representing a direct loss of potential revenue.
Flux imprévisible & Colmatage: Variable slag feed size, teneur en humidité, and the presence of tramp metal can cause frequent jams and unscheduled stoppages, disrupting your entire downstream workflow.
Poussière & Noise Compliance: Processing generates significant dust and noise, creating environmental and health challenges that require costly secondary containment systems to meet regulatory standards.
Complexité opérationnelle élevée: Equipment that requires constant adjustment and skilled monitoring increases labor costs and the potential for operator error.

A sustainable operation requires a processing solution engineered specifically for these rigors. How do you achieve higher throughput with lower operating costs and maximized resource recovery?

2. APERÇU DU PRODUIT

The Sustainable Slag Crusher Plant is a heavyduty, integrated processing system designed for the primary and secondary crushing of aircooled or granulated blast furnace (petit ami) slag and steel slag. It transforms variable feed material into precisely graded aggregates for use in construction or prepares it for further metallic recovery.

Flux de travail opérationnel:
1. Alimentation & Présélection: Incoming slag is fed via apron feeder to a scalping screen, removing fine fractions (10mm) to bypass unnecessary crushing.
2. Concassage primaire & Libération: Oversize material enters a robust jaw crusher or impact crusher for initial size reduction, effectively fracturing the slag matrix to liberate embedded metallics.
3. Metallic Separation: Crushed material passes over an overhead magnetic separator, extracting ferrous metal for recycling revenue.
4. Concassage secondaire & Classement: The remaining material is conveyed to a secondary cone or impact crusher for final sizing, then to screening decks to produce saleable aggregate fractions (par ex., 05mm, 510mm, 1020mm).
5. Suppression de la poussière: An integrated water spray system at transfer points controls dust emissions throughout the process.

Champ d'application & Limites:
Portée: Idéal pour les aciéries intégrées, fonderies, chantiers de traitement de scories autonomes, et producteurs de granulats traitant des scories BF, voler un coup, and nonferrous slags. Capable of processing feed sizes up to 800mm.
Limites: Not designed for primary metal shredding or processing of raw ore. Feed material with excessive claylike moisture may require predrying. Maximum hardness should not exceed that of typical slags (Mohs 78).
