Your Crushing Throughput is Capped. Your Downtime is Rising. Your Feed Variability is Costing You $150,000+ Per Shift.

Every plant manager in the iron ore sector faces the same triad of pressure: maintaining a consistent P80 of 1215mm for downstream ball mills, managing the extreme abrasion of Banded Iron Formation (FIF) minerai, and keeping operating costs below $2.50 per ton. When your current circuit experiences a 4hour liner change or a crusher stall due to tramp iron, you lose not just production time but the entire shift’s energy efficiency curve.

Are your current suppliers delivering equipment that matches the specific compressive strength (200400 MPa) of your hematite or magnetite feed? Can your existing plant handle the moisture variability of 38% sans colmatage? If you are sourcing a new commercial iron ore crushing plant, you need a solution engineered for 24/7 opération, not a modified aggregate plant.

Présentation du produit: The HeavyDuty Iron Ore Reduction Circuit

UN commercial iron ore crushing plant is a multistage, closedloop system designed to reduce runofmine (ROM) ore from 1200mm to a final product of 25mm or finer for beneficiation. Ce n'est pas une seule machine; it is an integrated workflow.

Flux de travail opérationnel:
1. Primary Gyratory Reduction: Flux ROM (8001200mm) is crushed to 150200mm using a 6089 inch gyratory crusher, handling up to 6,000 TPH.
2. Concassage secondaire à cône: The material is fed into heavyduty cone crushers (par ex., CH880 or MP series equivalents) for secondary reduction to 5075mm.
3. Tertiary HighPressure Grinding: The final stage utilizes HighPressure Grinding Rolls (HPGR) or specialized tertiary cone crushers to achieve the target P80 of 1012mm.
4. Dépistage & Recirculation: Vibrating banana screens (à deux étages) separate the product. Matériau surdimensionné (>25mm) is recirculated back to the tertiary crusher.

Champ d'application:

• Utilisation principale: Prebeneficiation crushing for DMS (Dense Media Separation) plants and magnetic separation circuits.
• Limites: Not designed for highclay lateritic ores (>15% teneur en argile) without a dedicated washing/scalping system. Throughput drops significantly with feed moisture above 10%.

Foire aux questions

T1: Can a commercial iron ore crushing plant handle both hematite and magnetite feed?
Oui. The plant is designed with a wide CSS range and variable speed drives. For hematite (plus doux, abrasif), you run higher speed and tighter CSS. For magnetite (Plus fort, less abrasive), you reduce speed and increase crushing force. The HPGR pressure can be adjusted from 3 N/mm² to 6 N/mm².

T2: Quel est le délai de livraison habituel pour un 10 MTPA plant?
Le délai de livraison standard est 1416 mois de la commande au port FOB. Cela comprend 8 months for fabrication, 2 months for assembly testing, et 4 months for shipping. Livraison accélérée (12 mois) est disponible avec un 10% prime.

T3: How does the plant handle tramp iron from the mine?
The primary gyratory has a hydraulic relief system that drops the main shaft by 50mm in 0.5 secondes. The secondary and tertiary cones have a "clearing chamber" cycle that automatically opens the CSS to 100mm for 30 seconds to pass the object, then returns to the set point.

T4: What is the expected liner life for the tertiary HPGR?
HPGR tire life (studded or hexadur) is typically 6,00010,000 hours for iron ore. This is highly dependent on feed abrasivity (AI index). We guarantee a minimum of 8,000 hours for ores with an AI < 0.4.

Q5: Can the plant be expanded from 10 MTPA to 15 MTPA later?
Oui. The modular design allows for the addition of a second tertiary cone or a larger HPGR unit. The conveyor system is designed with 20% excess capacity. The electrical room includes spare VFD slots for future drives.

Q6: Quelles sont les exigences en matière de puissance pour un 10 MTPA plant?
La charge totale connectée est d'environ 14 AMIU. You will need a 33 kV incoming supply. The plant includes a 2 MVA transformer for the primary and secondary circuit, et un 12 MVA transformer for the HPGR drives.

Q7: What is the warranty on the main crusher shafts?
The main shaft and eccentric assembly carry a 5year warranty against manufacturing defects. Pièces d'usure (doublures, manteaux, concaves) sont exclus. The hydraulic system carries a 2year warranty on pumps and valves.
