1. PAINPOINT DRIVEN OPENING

Managing the primary crushing stage for iron ore is a critical bottleneck with severe financial implications. Are you facing these persistent operational challenges?

Unplanned Downtime from Tramp Metal & Oversize: A single uncrushable object can halt your entire primary circuit, costing thousands per hour in lost production and requiring risky, manual clearing procedures.
Inconsistent Feed Size & Throughput: Variable runofmine ore geometry leads to cavity packing, uneven wear, and cyclical throughput, preventing your downstream processing plant from operating at its designed, optimal capacity.
Excessive Maintenance Cycles & Parts Costs: The abrasive nature of iron ore accelerates wear on mantles, concaves, and liners. Frequent changeouts not only incur high parts costs but also extend periods of nonrevenuegenerating maintenance.
High Energy Cost per Tonne: An inefficient or improperly configured primary crusher draws excessive power without delivering proportional throughput, directly eroding your profit margin on every ton processed.
Safety Risks in Feed Area: Manual intervention to address blockages or manage the feed apron is a significant hazard.

Is your current primary crushing solution a source of reliability issues and unpredictable cost? What would a 1520% improvement in overall plant availability mean for your annual tonnage?

2. PRODUCT OVERVIEW

The Bespoke Iron Ore Primary Crushing Station is a heavyduty, engineeredtoorder system centered on a gyratory or jaw crusher specifically configured for highabrasion, hightonnage iron ore applications. It is designed as the first and most robust stage of size reduction, transforming runofmine (ROM) ore into a consistent, conveyable product for secondary processing.

Operational Workflow:
1. ROM ore is dumped directly from haul trucks into a reinforced rock box or onto a heavyduty apron feeder.
2. The feeder regulates material flow into the primary crusher, ensuring optimal cavity filling and preventing chokefeeding.
3. The crusher utilizes compressive force to break large lumps (often up to 1.5m) down to a nominal product size of 200250mm.
4. Crushed material discharges onto a primary conveyor system for transport to the next stage of processing or stockpiling.

Application Scope: This solution is designed for greenfield mining projects or major expansion upgrades requiring reliable, highcapacity (5,000 12,000+ tph) primary reduction of magnetite or hematite ores.

Limitations: This is a fixedplant solution requiring significant foundational and structural civil works. It is not suitable for mobile or semimobile applications without substantial modification.
