1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Vos opérations de traitement de l'or sont-elles limitées par une taille d'alimentation incohérente ?, coûts d'usure excessifs du revêtement, et temps d'arrêt imprévus? Un concassage primaire inefficace impacte directement l’ensemble de votre circuit de valorisation, conduisant à:
Goulots d’étranglement du débit: Undersized crushers choke your SAG mill, limiting overall plant capacity.
Coûts de maintenance élevés: Frequent jaw plate or mantle changes halt production for hours, with replacement part expenses eroding margins.
Mauvaises caractéristiques de libération: Incorrectly sized ore reduces grinding circuit efficiency and can negatively affect downstream cyanidation or gravity recovery rates.

Is your primary crushing station the weakest link in your profit chain? The solution begins with selecting the right heavyduty equipment engineered for the specific abrasiveness and variability of gold ore.

2. APERÇU DU PRODUIT: HEAVYDUTY JAW CRUSHER FOR GOLD ORE PRIMARY REDUCTION

Cette gamme de produits comprend une gamme de robustes, highcapacity jaw crushers designed specifically for the primary crushing stage of gold ore processing. Le flux de travail opérationnel est conçu pour la fiabilité:
1. Consommation alimentaire: Runofmine (ROM) ore is delivered via haul truck or loader into a vibrating grizzly feeder (facultatif), which removes fines and bypasses undersize material.
2. Réduction primaire: Ore is crushed between a fixed and a reciprocating manganese steel jaw plate, applying compressive force to reduce material to a targeted top size.
3. Décharge: Crushed product is discharged onto the main conveyor system for transport to secondary crushing or directly to the grinding circuit.

Champ d'application: Idéal pour les minerais d'or en roche dure (quartz, contenant des sulfures), providing the first critical size reduction. Limites: Non conçu comme une solution autonome; requires integration with feeding and conveying systems and is typically followed by secondary/tertiary crushing for mill feed preparation.
