1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

L’augmentation des coûts opérationnels et les temps d’arrêt imprévisibles érodent vos marges de production globales? Pour les directeurs d’usine et les entrepreneurs en ingénierie, les principaux défis du concassage primaire proviennent souvent du concasseur lui-même. Les points douloureux courants incluent:
Coûts excessifs des pièces d’usure: Remplacement fréquent des manteaux, 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.
Gradation du produit incohérente: Les fluctuations de la taille ou de la dureté des aliments entraînent un produit hors spécifications., causing bottlenecks in secondary circuits and reducing plantwide efficiency.
Consommation d'énergie élevée par tonne: Inefficient crushing chambers and drive systems translate directly to unsustainable power costs, une dépense opérationnelle principale.
Limites de configuration rigides: 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. APERÇU DU PRODUIT

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.

Flux de travail opérationnel:
1. Consommation alimentaire: Large dump trucks or loaders deposit runofmine material into the crusher’s robust feed hopper.
2. Concassage compressif: The central gyrating mantle eccentrically compresses the rock against the stationary concave liners, fracturing it through progressive reduction cycles.
3. Décharge: Crushed material gravitates through the continually narrowing chamber until it reaches the desired size and exits through the discharge opening (OSS).
4. Transport du produit: The nowprimarycrushed aggregate is conveyed to downstream screening and secondary crushing stages.

Champ d'application & Limites:
Portée: Idéal pour les grandes capacités (1,500+ TPH) opérations minières, carrières de granulats à grande échelle, and industrial mineral processing plants handling abrasive materials like granite, basalte, minerai de fer, et minerai de cuivre.
Limites: Ne convient pas aux opérations de faible tonnage (<500 TPH) due to capital cost considerations. Nécessite une écurie, 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. SCÉNARIOS D'APPLICATION

LargeScale Granite Quarrying Operation

Défi: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).Résultats:Liner changeout time was reduced consistently to under one day (<24 heures). This increased annual crusher availability by approximately eight days directly attributable to maintenance speed alone.

Copper Mine Primary Crushing Circuit

Défi: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.Résultats: 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.
