1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are escalating operational costs and unpredictable throughput crippling your gold processing profitability? L’étape primaire de concassage donne le ton à l’ensemble de votre circuit de valorisation, and inefficiencies here cascade into significant financial losses. Considérez ces défis communs:
Temps d'arrêt élevés pour la maintenance: Frequent liner changes and unplanned repairs in your primary crusher halt your entire milling circuit, coûtant des milliers de dollars par heure en perte de production.
Réduction incohérente de la taille des aliments: Variable ore hardness leads to fluctuating discharge sizes, overloading your SAG mill or secondary crushers and reducing overall plant efficiency by 1525%.
Consommation d'énergie excessive: An inefficient or improperly sized primary crusher can be the single largest consumer of power in your comminution circuit, érodant directement les marges bénéficiaires.
Défaillance prématurée des pièces d’usure: Minerais d'or abrasifs, en particulier ceux à haute teneur en silice, can devastate standard manganese steel, leading to unsustainable consumable costs and contamination risks.

Is your current primary crushing solution a reliable asset or a constant source of bottleneck and cost? The right heavyduty jaw crusher is not just equipment; it is the foundational investment for predictable, lowcost tonnage.

2. APERÇU DU PRODUIT: BROYEUR À MÂCHOIRES ROBUSTE POUR LA RÉDUCTION PRIMAIRE DU MINERAI D'OR

Cette gamme de produits comprend une gamme de robustes, stationary and modular jaw crushers engineered specifically for the rigorous duty of primary gold ore crushing. Conçu pour accepter le runofmine (ROM) feed directly from the mine haul truck dump pocket, these machines provide the first critical size reduction.

Flux de travail opérationnel:
1. ROM Ore Intake: Direct dump from haul trucks (jusqu'à 1,5 m de grumeaux) into a vibrating grizzly feeder (facultatif) qui scalpe les matières fines.
2. Concassage primaire: Le minerai est saisi et broyé entre une mâchoire fixe et une mâchoire mobile actionnée mécaniquement., utilizing compressive force.
3. Décharge & Transport: Produit broyé (typically reduced to 150250mm) is discharged onto a main conveyor belt for transport to the next stage of processing (SAG mill or secondary crushing).

Champ d'application: Idéal pour les minerais d'or en roche dure (gisements de filons), y compris les minerais sulfurés. Suitable for both greenfield installations and retrofit upgrades in existing CIP/CIL plants.

Limites: Non conçu pour être mouillé, minerais collants sans criblage/scalping préalable. Maximum feed size is determined by modelspecific gape dimensions.
