1. PAINPOINT DRIVEN OPENING

Managing an iron ore crushing plant presents distinct operational and financial challenges. Are you experiencing any of these critical issues?
Unplanned Downtime: Catastrophic failures in crusher components, like main shafts or bearings, can halt your entire primary circuit for days. Each hour of lost production represents significant, unrecoverable revenue.
Excessive Maintenance Costs: The abrasive nature of iron ore accelerates wear on liners, mantles, and screens. Frequent changeouts not only incur high parts costs but also require extensive labor hours, pulling technicians from preventative tasks elsewhere.
Inconsistent Throughput & Product Size: Fluctuations in feed size or hardness can cause chokefeeding or cavitation, leading to suboptimal tonnage and offspec product that affects downstream processing efficiency.
High Energy Consumption: Older or improperly configured crushing stages operate below peak efficiency, making kWh per tonne a major and growing operational expense.
Space & Logistics Constraints: Integrating new capacity or upgrading existing circuits within a fixed plant footprint requires precise equipment sizing and layout planning.

The central question is: how can you achieve higher availability, predictable operating costs, and optimal yield from your primary crushing stage? The specification of your primary iron ore crushing plant is the foundational answer.

2. PRODUCT OVERVIEW

This specification outlines a heavyduty, stationary primary crushing station engineered explicitly for hightonnage iron ore processing. The core configuration typically centers on a gyratory or jaw crusher designed for maximum reliability and feed acceptance.

Operational Workflow:
1. Feed Intake: Runofmine (ROM) iron ore is delivered via haul trucks to a robust dump hopper, equipped with a grizzly to bypass subfines.
2. Primary Reduction: A vibrating feeder regulates material flow into the primary crusher, where compressive force breaks down the ore to a manageable top size.
3. Primary Conveyance: Crushed product is discharged onto a main conveyor belt for transport to secondary crushing or stockpiling.

Application Scope: This solution is designed for largescale mining operations with annual throughput requirements exceeding 1 million tonnes. It is suitable for magnetite, hematite, and other ironbearing ores with compressive strengths up to 350 MPa.

Key Limitations: This primary station is not a complete processing plant. It requires integration with downstream screening, secondary/tertiary crushing, and material handling systems. Feed size must be controlled within the crusher's designed maximum opening.
