Targeted Iron Ore Crushing Plant Solutions for HighTonnage, HighAvailability Operations

Are your crushing circuits struggling to keep pace with production targets while maintenance costs escalate? For plant managers and engineering contractors, the bottlenecks in primary and secondary crushing directly impact downstream processing and overall site profitability. Common pain points include:
Unplanned Downtime: Bearing failures or wear part changes in abrasive iron ore applications can halt production for 1224 hours, costing upwards of $50,000 per hour in lost throughput.
Inconsistent Feed Size: Fluctuations in ROM (Run of Mine) ore size and hardness lead to crusher chokefeed or idle running, reducing optimal capacity by 1530% and increasing specific energy consumption.
High Operational Costs: Premature wear on mantles, concaves, and jaw plates due to nonoptimized crushing chambers and inadequate material flow design can increase consumable costs by 40%.
Dust & Vibration Management: Excessive dust generation at transfer points creates environmental compliance risks and health hazards, while uncontrolled vibration accelerates structural fatigue.

The central question is: how can you achieve a reliable, highyield crushing circuit that delivers consistent 6" product for your SAG mills or 1.5" for your ball mill lines, while controlling total operational expenditure?

Product Overview: HeavyDuty Custom Iron Ore Crushing Stations

Our engineered solution is a customconfigured stationary or semimobile crushing plant specifically designed for the abrasive and highdensity characteristics of magnetite and hematite ores. The system integrates primary, secondary, and tertiary crushing modules with robust feeding, screening, and material handling components.

Operational Workflow:
1. Primary Reduction: Dump trucks or shovels feed ROM iron ore (up to 48") into a heavyduty apron feeder, which regulates material flow to a gyratory or jaw crusher for initial reduction.
2. PreScreening & Secondary Crushing: Primary crushed material is conveyed to a scalping screen. Oversize is routed to a cone crusher for secondary reduction. This closedcircuit design ensures optimal feed size for downstream grinding.
3. Tertiary Crushing & Product Sizing: For plants requiring finer product, a tertiary cone crusher stage operates in closed circuit with final sizing screens to achieve precise product specifications (e.g., 25mm or 19mm).

Application Scope: Ideal for greenfield mine development or brownfield expansion projects requiring processing capacities from 1,000 to over 10,000 tonnes per hour (tph). Limitations include requirement for significant foundational engineering and capital investment; not suitable for smallscale or exploratory operations.
