Bespoke Iron Ore Crushing Plant R&D

1. PAINPOINT DRIVEN OPENING

Is your current iron ore crushing circuit struggling with feed variability, resulting in a 1218% reduction in throughput during wet season processing? Are you facing escalating liner replacement costs exceeding $0.45 per ton due to excessive abrasion from highsilica gangue? Does your existing plant’s fixed configuration limit your ability to adapt to declining ore grades, forcing you to either overcrush or underprocess material?

These operational challenges—unplanned downtime averaging 14 days per year, energy consumption spikes of 1520% during hard ore zones, and product consistency issues leading to downstream pellet plant penalties—are costing operations between $2M and $5M annually in lost revenue and maintenance overhead. How can you design a crushing solution that adapts to your specific deposit characteristics without requiring a complete plant rebuild every three years?

2. PRODUCT OVERVIEW

The Bespoke Iron Ore Crushing Plant R&D is a customengineered, multistage crushing system designed for greenfield and brownfield iron ore projects requiring specific particle size distribution (PSD) control for downstream beneficiation. Unlike offtheshelf plants, this solution integrates sitespecific metallurgical data from your deposit into the mechanical design.

Operational Workflow:
1. Feed Preparation: ROM ore (8001200mm) passes through an apron feeder with variable speed control, matched to crusher cavity fill levels.
2. Primary Jaw Crushing: A heavyduty jaw crusher reduces material to 250mm with hydraulic CSS adjustment for wear compensation.
3. Secondary Cone Crushing: An automated cone crusher with realtime power draw monitoring reduces material to 75mm while maintaining a flakiness index below 15%.
4. Tertiary HPGR Integration: Highpressure grinding rolls (HPGR) provide microfracturing of hematite/magnetite particles at 46 kWh/t, reducing Bond Work Index by 812% for subsequent ball milling.
5. ClosedCircuit Screening: Multideck banana screens with polyurethane media ensure 6mm fines removal at >95% efficiency.

Application Scope & Limitations:

• Scope: Suitable for hematite, magnetite, and goethitic ores with compressive strengths up to 350 MPa; ideal for plants processing 5004,000 tph.
• Limitations: Not recommended for ores exceeding 12% moisture content without predrying; requires minimum site access width of 25m for installation.
