1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Managing slag byproduct is a persistent operational bottleneck with direct cost implications. Êtes-vous confronté à ces défis communs?
Temps d'arrêt élevés pour la maintenance: Frequent liner changes and unplanned stoppages in your crushing circuit halt downstream processing, coûtant des milliers de dollars par heure en perte de débit.
Usure excessive & Coûts de remplacement: La nature abrasive des scories dégrade rapidement les composants standard du concasseur., leading to unsustainable spending on wear parts and associated labor.
Gradation du produit incohérente: Poor control over final aggregate size results in offspec material, reducing its market value for secondary applications in construction or cement blending.
Coûts opérationnels élevés: Inefficient power consumption per ton processed and the need for secondary equipment to handle uncrushable metals directly impact your bottomline profitability.
Espace & Contraintes logistiques: Integrating a robust processing system into an existing plant layout often seems prohibitive, leading to suboptimal manual handling or costly thirdparty processing.

Is your current solution equipped to transform this challenging material into a consistent, highvalue product while controlling operational expenditure?

2. APERÇU DU PRODUIT

The Commercial Slag Crusher Plant is a stationary or semimobile processing system engineered specifically for the primary and secondary reduction of metallurgical slag (haut fourneau, four à acier). It is designed to process large feed material into precisely graded aggregate for use in road base, concrete additives, ou ballast ferroviaire.

Flux de travail opérationnel:
1. Alimentation & Présélection: Les scories tout-venant sont alimentées via un chargeur ou un convoyeur. An optional prescreening grizzly removes fine fractions to bypass the crusher, augmenter l’efficacité globale de l’usine.
2. Concassage primaire & Séparation des métaux: A heavyduty jaw crusher or impactor performs initial size reduction. Integrated tramp metal discharge systems (par ex., belt magnets, metal detectors) protect downstream components by removing uncrushable ferrous material.
3. Concassage secondaire & Dimensionnement: A cone crusher or secondary impactor further reduces the material. Critical adjustments here define the final product gradation curve.
4. Projection finale & Stockage: Vibrating screens classify the crushed slag into multiple specification products (par ex., 05mm, 520mm, 2040mm), qui sont acheminés vers des stocks désignés.

Champ d'application & Limites:
Portée: Idéal pour les aciéries intégrées, scrap processing yards, and independent aggregate producers handling blast furnace (BFS) ou laitier d'acier (BOF/EAF). Capable of processing feed sizes up to 800mm.
Limites: Not designed for primary rock mining operations or processing slag with excessive uncrushable, nonferrous contamination without specialized presorting. Maximum feed hardness should not exceed that of typical granulated or aircooled slag.
