1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Les coûts opérationnels croissants et la disponibilité imprévisible érodent-ils la rentabilité de votre circuit de concassage principal ?? Pour les directeurs d’usine et les entrepreneurs en ingénierie, l'étape de concassage primaire est un goulot d'étranglement critique où les inefficacités se répercutent sur l'ensemble du processus en aval. Les défis courants rencontrés avec les concasseurs giratoires traditionnels comprennent:

Temps d'arrêt excessif pour la maintenance: Fréquent, lengthy liner changes and unexpected mechanical failures halt production for days, directly impacting tonsperhour metrics and revenue.
Haut opérationnel & Coûts énergétiques: Inefficient crushing chambers and outdated drive systems consume excessive power per ton of material processed, while rapid wear part consumption drives up costperton figures.
Taille du produit incohérente & Capacité: Fluctuations in feed material can lead to poor setting control, resulting in offspec product that stresses secondary crushers and reduces overall plant throughput.
Surveillance intensive du travail & Ajustement: Reliance on manual checks for wear and performance optimization increases labor costs and the risk of human error leading to catastrophic damage.

Votre exploitation est-elle équipée pour surmonter ces défis? The solution lies in a fundamentally redesigned ODM gyratory crusher engineered for the demands of modern, highvolume mineral processing.

2. APERÇU DU PRODUIT: ODM Gyratory Crusher

Le concasseur giratoire ODM est un robuste, primary crushing machine designed for the first stage of reducing runofmine ore or quarry rock. It operates on the principle of a gyrating mantle within a concave crushing chamber, creating a progressive crushing action ideal for hightonnage, matériaux abrasifs.

Flux de travail opérationnel:
1. Consommation alimentaire: Largesized feed material is directed into the top of the crusher’s deep chamber via dump trucks, chargeurs, ou un alimentateur principal.
2. Concassage progressif: Le manteau à rotation excentrique comprime continuellement le matériau contre les concaves stationnaires., breaking it into smaller fragments through a combination of impact and attrition.
3. Décharge: Crushed product exits through the bottom discharge opening (OSS), with size primarily controlled by the closedside setting of the mantle.

Champ d'application & Limites:
Portée: Optimized for highcapacity (2,000+ tph) concassage primaire de roche dure (granit, basalte), minerai de fer, minerai de cuivre, and gold ore. Suitable for both stationary plants and semimobile installations.
Limites: Not designed for recycled concrete/asphalt or lowabrasion materials better suited for jaw crushers. Nécessite une écurie, reinforced concrete foundation and significant vertical space for installation and maintenance access.
