1. PAINPOINT DRIVEN OPENING

Managing an iron ore crushing plant presents distinct and costly operational challenges. Plant managers and engineering contractors consistently face the high costs of unplanned downtime, excessive wear part consumption, and inconsistent final product sizing. Are you contending with premature failure of crusher liners under extreme abrasion, leading to frequent, expensive changeouts? Is your current circuit struggling to maintain target throughput as ore hardness varies, creating bottlenecks? Are you managing energy costs that escalate with inefficient reduction processes? These issues directly impact your costperton metric and overall plant availability. The selection of a primary crushing station is not merely an equipment purchase; it is a strategic decision determining your site’s productivity and profitability for years.

2. PRODUCT OVERVIEW

This solution is a heavyduty, stationary primary iron ore crushing plant, engineered for the first stage of size reduction in mining operations. The typical operational workflow involves: 1) Feed Reception: Direct dump from haul trucks into a rugged grizzly feeder. 2) PreScreening & Bypass: Scalping of fine material to bypass the crusher, increasing effective capacity. 3) Primary Crushing: Reduction of runofmine (ROM) ore by a highcapacity jaw or gyratory crusher. 4) Discharge Conveying: Transport of crushed product to downstream processing.

Its application scope is the primary crushing of magnetite or hematite ores with high abrasiveness and compressive strength. A key limitation is feed size; it is designed for ROM ore up to a specified maximum lump dimension (e.g., 1.5m). It is not suitable for alreadyscreened or fine materials, which are better handled by secondary or tertiary circuits.

3. CORE FEATURES

Modular Chassis | Technical Basis: Preengineered, bolttogether structural framework | Operational Benefit: Reduces site installation time and civil work costs by up to 30% compared to traditional builtinplace foundations | ROI Impact: Faster commissioning accelerates revenue generation from processed ore.

6. APPLICATION SCENARIOS

LargeScale Open Pit Mine Expansion

Challenge: An existing mine needed to double primary crushing capacity but had limited space on the existing plant footprint and a tight commissioning schedule.
Solution: Implementation of a modular iron ore crushing plant with a largecapacity gyratory crusher adjacent to the existing circuit.
Results: The modular design reduced civil works by an estimated $250k USD and cut six weeks off the schedule. The new circuit achieved nameplate capacity within one week of startup.

HighAbrasion Hematite Processing

Challenge: A processing plant faced excessive wear costs in its primary stage due to highly abrasive hematite ore; liner changes were occurring every five weeks.
Solution: Installation of an iron ore crushing plant featuring our proprietary abrasionresistant liner system paired with an optimized cavity profile.
Results: Liner life was extended by an average of seven weeks per set—a greater than 50% improvement—reducing annual wear part expenditure by over $180k USD.
