1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are your iron ore processing profits being eroded by persistent, temps d'arrêt imprévu? Plant managers and engineering contractors face significant operational hurdles that directly impact the bottom line. Les défis courants incluent:

Usure excessive & Défaillance d'un composant: Minerai de fer abrasif, particularly hematite and magnetite with high silica content, rapidly degrades crusher liners and wear parts, leading to frequent maintenance stops and high consumables costs.
Débit incohérent & Taille du produit: Fluctuations in feed size or hardness can cause chokefeeding or cavity packing, resulting in suboptimal tonnage and offspec product that affects downstream beneficiation efficiency.
Consommation d'énergie élevée par tonne: Older or improperly configured crushing stages consume disproportionate power for the processed tonnage, faire de l’énergie un coût variable majeur.
Arrêts imprévus chez Tramp Metal: Despite precautions, occasional tramp steel from mining equipment can enter the circuit, risking catastrophic damage to crusher internals and hours of lost production.

La question centrale est: how can you achieve a reliable, predictable flow of optimally sized material while controlling operational expenditure? The answer lies in a purposeengineered iron ore crushing plant designed not just to crush, but to optimize your entire mineral processing chain.

2. APERÇU DU PRODUIT

This solution is a fully customized, stationary or semimobile primary and secondary iron ore crushing plant. It is engineered from the ground up for continuous, hightonnage processing of abrasive ironbearing materials.

Flux de travail opérationnel:
1. Réduction primaire: Runofmine (ROM) iron ore is fed into a robust primary crusher (par ex., gyratory or jaw crusher) for initial size reduction to a manageable diameter.
2. Présélection & Scalping: A heavyduty scalper removes fine material and bypasses it from the secondary circuit, augmenter l'efficacité et réduire l'usure.
3. Concassage secondaire & Façonner: The precrushed ore is conveyed to secondary crushers (typically cone crushers) for further reduction and shaping to a consistent product size.
4. Product Screening & Classification: Vibrating screens classify the crushed material into specified fractions, with oversize material recirculated (circuit fermé) pour réécraser.
5. Stockage: Correctly sized product is conveyed to designated stockpiles for downstream beneficiation.

Champ d'application: Designed for medium to largescale mining operations processing taconite, magnétite, or hematite ores. Ideal for greenfield projects or brownfield plant upgrades requiring higher capacity or improved product control.

Limites: Not suitable for smallscale or pilot operations with sub500 TPH requirements. Full customization requires detailed ore characterization data (indice de travail, indice d'abrasion, teneur en humidité) for optimal engineering.
