ROHS Compliant Iron Ore Crushing Plant | Engineered for Sustainable, HighYield Mineral Processing

1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Managing an iron ore processing operation involves navigating a complex set of efficiency, environmental, and maintenance challenges. Vivez-vous:
Temps d'arrêt imprévus & Contamination: Component failures from nonspecialized wear parts lead to costly stoppages. De manière plus critique, standard machinery can introduce restricted hazardous substances (comme du plomb, cadmium, mercure) into your material stream, jeopardizing product purity and RoHS compliance for downstream steelmakers.
Inefficient Throughput & High Energy Cost: Inconsistent feed size reduction creates bottlenecks, forcing secondary and tertiary crushers to work harder. This directly increases power consumption per ton of processed ore, érosion des marges bénéficiaires.
Travail d'entretien excessif & Inventaire des pièces: Changements fréquents de doublure, défaillances de roulements, and unplanned repairs demand significant technician hours and require a large inventory of spare parts, tying up capital and increasing total operational cost.
Environmental Compliance Risk: As global supply chains mandate stricter material declarations (RoHS, REACH), noncompliant equipment can be a source of contamination, risking contract violations and reputational damage.

La question centrale pour les directeurs d'usine est: how can you achieve reliable throughput while futureproofing your operation against stringent environmental material regulations?

2. APERÇU DU PRODUIT

UN RoHS Compliant Iron Ore Crushing Plant is a configured system of primary, secondaire, et concasseurs tertiaires, tels que les concasseurs à mâchoires, concasseurs giratoires, and cone crushers—along with screens and conveyors, where all wear parts, lubrifiants, scellés, and electrical components are certified free of Restricted Hazardous Substances per Directive 2011/65/EU.

Flux de travail opérationnel:
1. Concassage primaire: ROM (RunofMine) iron ore is reduced to <200mm by a RoHScompliant jaw or gyratory crusher with certified manganese steel jaws/liners.
2. Dépistage & Concassage secondaire: Oversize material is routed to a cone crusher for further reduction. All screen meshes and crusher liners in the contact path are manufactured from compliant alloys.
3. Concassage Tertiaire & Dimensionnement final: Pour des besoins spécifiques en matière d'alimentation en pellets ou en alimentation frittée, additional crushing stages ensure precise particle size distribution using compliant vertical shaft impactors (ISBC) or fine cone crushers.

Champ d'application: Ideal for greenfield projects or retrofits supplying the international steel industry where RoHS/REACH material declarations are required. Convient à la magnétite, hématite, et minerais de taconite.

Limites: Maximum feed size and throughput are determined by the specific plant configuration. Not designed for processing materials outside typical iron ore abrasion indices without specific liner customization.
