1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are escalating operational costs and unpredictable throughput eroding your gold processing margins? Processing gold ore presents distinct challenges that directly impact profitability. Les obstacles opérationnels courants comprennent:
Haute abrasion & Temps d'arrêt: Quartz and other abrasive minerals in gold ore rapidly wear crusher components, leading to frequent maintenance stops and high parts replacement costs.
Libération inefficace: Inadequate primary crushing creates poorly sized feed for milling circuits, hindering optimal gold liberation and recovery rates.
Arrêts imprévus: Equipment not engineered for the specific impact and abrasion of hard rock gold deposits fails prematurely, causing costly, unbudgeted downtime.
Intensité énergétique: Older crushing stages consume excessive power per ton of ore processed, making energy a dominant and volatile cost factor.
Sécurité & Reliability Risks: Overreliance on manual intervention for jam clearing or maintenance increases exposure to safety incidents.

Is your current crushing circuit a consistent bottleneck? Are you seeking a reliable private label solution that balances capital efficiency with longterm operating cost control?

2. APERÇU DU PRODUIT

Our Private Label Gold Ore Crushing Equipment is engineered as a robust, highcapacity primary jaw crusher solution designed specifically for the demanding environment of hard rock gold mining. This equipment forms the critical first stage in a comminution circuit, setting the foundation for downstream recovery efficiency.

Flux de travail opérationnel:
1. Consommation alimentaire: Runofmine (ROM) gold ore is fed into the vibrating grizzly feeder (facultatif), which bypasses fines to optimize crusher loading.
2. Réduction primaire: Ore is crushed within a reinforced crushing chamber by a highinertia moving jaw against a fixed jaw.
3. Décharge du produit: The crushed product discharges at a preset closedside setting (CSS), assurer une cohérence, targetsized output for conveyor transport to secondary crushing or stacking.

Champ d'application: Ideal for stationary or semimobile plant installations processing lode or veintype gold ores with high compressive strength and abrasiveness (par ex., quartz, roche sulfurée).

Limites: This primary crusher is not designed as a standalone solution for final product sizing; it requires integration with secondary/tertiary crushing and grinding circuits for optimal liberation. It is also not suited for processing placer/alluvial material without significant feed preparation.
