1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Vos opérations de traitement de l’or sont-elles limitées par un concassage primaire inefficace ?? Common challenges with suboptimal gold ore crushing equipment directly impact your bottom line: temps d'arrêt excessif pour les changements de revêtement et la maintenance, inconsistent feed size causing bottlenecks in downstream milling circuits, and high energy consumption per ton of ore processed. En outre, abrasive gold ores with high silica content accelerate wear part costs, while inadequate throughput forces you to leave potential tonnage—and revenue—unmined. Êtes-vous confronté à une augmentation des coûts opérationnels, disponibilité imprévisible, and an inability to fully leverage your mineral deposit? The solution begins with selecting the right primary crushing technology engineered specifically for the demands of gold ore.

2. APERÇU DU PRODUIT

Cette gamme de produits englobe les poids lourds, stationary primary jaw crushers and gyratory crushers designed explicitly for the rigorous first reduction stage of runofmine (ROM) minerai d'or. Le flux de travail opérationnel est conçu pour une disponibilité maximale: (1) ROM ore is fed via dump truck or loader into a rugged vibrating grizzly feeder, (2) oversize material is directed into the crusher’s chamber for compressive reduction, (3) crushed product is discharged onto a main conveyor at a consistent, predetermined size. These crushers are applied in hard rock gold mining operations processing lode or veintype deposits. They are not designed for wet, sticky ores without prior scalping or for ultrafine crushing duties best handled by secondary cone crushers or grinding mills.
