1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your aggregate production margins? For plant managers and engineering contractors, the core challenges in primary crushing often stem from the crusher itself. Common pain points include:
Excessive Wear Part Costs: Frequent replacement of mantles, concaves, and liners due to suboptimal chamber design or material quality, directly impacting your cost per ton.
Unscheduled Downtime for Maintenance: Difficult and timeconsuming wear part changes lead to prolonged production halts, missing critical delivery windows.
Inconsistent Product Gradation: Fluctuations in feed size or hardness result in an offspec product, causing bottlenecks in secondary circuits and reducing plantwide efficiency.
High Energy Consumption per Ton: Inefficient crushing chambers and drive systems translate directly to unsustainable power costs, a primary operational expense.
Rigid Configuration Limitations: Fixed base machines that cannot adapt to evolving site layouts or changing feed material characteristics.

How do you select a primary crusher that addresses these specific financial and operational liabilities? The solution requires a focus on engineered durability, maintenance accessibility, and process efficiency.

2. PRODUCT OVERVIEW

The ODM Gyratory Crusher is a heavyduty, primary compression crusher engineered for the first stage of reducing runofmine ore or large quarry rock. It is designed for hightonnage, continuous crushing operations where reliability is nonnegotiable.

Operational Workflow:
1. Feed Intake: Large dump trucks or loaders deposit runofmine material into the crusher’s robust feed hopper.
2. Compressive Crushing: The central gyrating mantle eccentrically compresses the rock against the stationary concave liners, fracturing it through progressive reduction cycles.
3. Discharge: Crushed material gravitates through the continually narrowing chamber until it reaches the desired size and exits through the discharge opening (OSS).
4. Product Conveyance: The nowprimarycrushed aggregate is conveyed to downstream screening and secondary crushing stages.

Application Scope & Limitations:
Scope: Ideal for highcapacity (1,500+ TPH) mining operations, largescale aggregate quarries, and industrial mineral processing plants handling abrasive materials like granite, basalt, iron ore, and copper ore.
Limitations: Not suitable for lowtonnage operations (<500 TPH) due to capital cost considerations. Requires a stable, reinforced concrete foundation and significant vertical space for installation. Less effective for nonabrasive, lowdensity materials where other crusher types may offer a cost advantage.

6. APPLICATION SCENARIOS

LargeScale Granite Quarrying Operation

Challenge:A major aggregate producer faced crippling downtime every six weeks for liner changes on their primary gyratory crusher—a process taking over three days—severely limiting output during peak construction season.Solution:The existing crusher was replaced with an ODM Gyratory Crusher featuring TopService Design (TSD).Results:Liner changeout time was reduced consistently to under one day (<24 hours). This increased annual crusher availability by approximately eight days directly attributable to maintenance speed alone.

Copper Mine Primary Crushing Circuit

Challenge:The existing primary gyratory experienced frequent tramp metal events from drill bits/ground engaging tools hidden in ROM ore feed.This led regularly bent main shafts or cracked frames,causing unscheduled outages averaging two weeks per incident.Solution:A new ODM Gyratory Crusher equipped with an advanced Hydroset tramp release system was installed as part of a plant expansion project.The system was integrated with metal detection on the feed conveyor as part of an automated protection circuit.Results: Over three years of operation,the tramp release system has successfully cleared over two dozen significant uncrushable objects without damage.Zero incidents of shaft bending have occurred,and related unscheduled downtime has been eliminated.
