1. PAINPOINT DRIVEN OPENING

Are you managing unpredictable throughput, excessive liner wear costs, and unplanned downtime in your primary crushing circuit? In iron ore processing, suboptimal primary crushing creates bottlenecks that ripple through your entire operation, directly impacting pellet and sinter feed consistency. Key challenges include:

High Abrasion Costs: Constant exposure to hard, abrasive hematite or magnetite leads to premature crusher liner failure. This results in frequent, costly shutdowns for replacement and significant consumable expenditure.
Throughput Inconsistency: An illsuited or aging primary crusher cannot maintain a steady feed to downstream grinding circuits, causing process instability and limiting overall plant capacity.
Unscheduled Downtime: Mechanical failures in critical components under high stress lead to catastrophic stoppages, jeopardizing production targets and maintenance budgets.
Size Distribution Issues: Inconsistent product sizing from the primary stage increases the load and energy consumption on secondary and tertiary crushers, raising your cost per ton.

Is your current solution equipped to handle the specific impact and abrasion of iron ore? Can you quantify your true cost of ownership from liner changes and energy use? The foundation of an efficient mineral processing plant begins with reliable, heavyduty primary comminution.

2. PRODUCT OVERVIEW

Our engineered solution is a turnkey Iron Ore Crushing Plant Contract, centered on robust, highcapacity primary gyratory or jaw crushers specifically configured for dense, abrasive ironbearing rock. We deliver a complete system from runofmine (ROM) receiving to a defined crushed product for secondary processing.

Operational Workflow:
1. ROM Receiving & PreScreening: Dump pocket or apron feeder receives direct haul truck feed. Grizzly screening removes subfines to bypass the crusher, improving efficiency.
2. Primary Crushing: The core heavyduty crusher reduces large lump ore (up to 1.5m) to a manageable product size (typically 250mm).
3. Material Handling: Robust belt conveyors with impactresistant idlers transport crushed material.
4. Stockpiling or Direct Feed: Crushed ore is either stockpiled for blending or conveyed directly to the next stage of the beneficiation circuit.

Application Scope & Limitations:
Scope: Ideal for greenfield installations or brownfield upgrades requiring highcapacity (2,000 10,000+ tph), continuousduty primary crushing of hard iron ores.
Limitations: Not designed for final product sizing; requires secondary/tertiary stages for fine crushing. Sitespecific geotechnical conditions must be evaluated for foundational support.

3. CORE FEATURES

HeavyDuty Manganese Liners | Technical Basis: Workhardening austenitic manganese steel | Operational Benefit: Liners develop a hardened surface layer during operation that resists cutting and gouging from abrasive ore | ROI Impact: Field data shows a 2035% increase in liner life compared to standard alloys, reducing part cost and changeout frequency.

Hydroset CSS Adjustment | Technical Basis: Hydraulic cylinder controls the crusher's closedside setting (CSS) | Operational Benefit: Operators can adjust product size or compensate for wear remotely under load in minutes | ROI Impact: Maintains optimal throughput and product gradation without stopping production, maximizing crusher utilization.

Integrated Tramp Iron Protection | Technical Basis: Hydraulic relief cylinders with automatic reset | Operational Benefit: Automatically releases uncrushable material (e.g., bucket teeth, drill bits) to prevent catastrophic damage to the main shaft and head | ROI Impact: Eliminates risk of major mechanical failure and associated weekslong downtime; protects core asset integrity.

Advanced Bearing Design | Technical Basis: Largediameter spherical roller bearings with circulating oil lubrication | Operational Benefit: Supports extreme radial loads and delivers reliable performance under shock loading from large feed blocks | ROI Impact: Industry testing demonstrates bearing service life exceeding 50,000 hours under proper maintenance, ensuring longterm reliability.

PLCBased Control & Monitoring System | Technical Basis: Centralized programmable logic controller with vibration sensors and temperature monitors | Operational Benefit: Provides realtime data on bearing health, lubrication status, and power draw for predictive maintenance scheduling | ROI Impact: Enables conditionbased maintenance planning over fixed schedules, preventing failures and optimizing component replacement cycles.

Modular Plant Design Philosophy | Technical Basis: Preengineered structural modules for major assemblies (crusher base, walkways, conveyor sections) | Operational Benefit: Reduces field fabrication time by up to 40%, accelerating commissioning schedules in remote locations | ROI Impact: Lowers total installed cost through reduced onsite labor hours and gets your revenuegenerating asset operational faster.

6. APPLICATION SCENARIOS

Greenfield Magnetite Concentrator Project

Challenge: A new mine required a primary crushing circuit capable of processing highly abrasive magnetite at 6,500 tph with >94% availability to meet stringent downstream grinding mill feed schedules.
Solution: Implementation of a turnkey iron ore crushing plant contract featuring a large gyratory crusher with automated setting adjustment and modular construction.
Results: The plant achieved nameplate capacity within two weeks of commissioning. Availability averaged 96.2% in the first year of operation against a contractual target of 94%. Modular build reduced onsite construction labor costs by an estimated USD $350k.

Brownfield Hematite Processing Upgrade

Challenge: An existing operation faced escalating costs due to bimonthly liner changes in their old jaw crusher and inconsistent feed size causing bottlenecks in SAG mill throughput.
Solution: Replacement with our modern gyratorybased iron ore crushing plant solution designed for higher throughput with superior wear life.
Results: Liner life extended from approximately 60 days to an average of 85 days—a direct reduction in consumable costs by nearly onethird per annum—while providing a more consistent 200mm product that improved SAG mill stability by approximately eight percent as measured by power draw consistency.

HighCapacity Direct Shipping Ore Operation

Challenge: A DSO producer needed extremely highvolume primary crushing (>8k tph) but had limited space available at their rail loadout facility due to existing infrastructure constraints
Solution: A compact yet highcapacity gyratory configuration paired with steepangle conveying systems was engineered specifically within tight spatial parameters
Results: The tailored design met all throughput requirements while fitting into only eighty percent of the space originally thought necessary saving significant capital that would have been required for site earthworks modifications
