1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Vos opérations de traitement de l’or sont-elles limitées par un concassage primaire inefficace ?? The bottleneck at this initial stage ripples through your entire circuit, impactant directement la rentabilité. Les défis courants incluent:

Temps d'arrêt excessif pour la maintenance: Frequent liner changes and unplanned repairs on abrasive gold ore halt your milling circuit, coûtant des milliers de dollars par heure en perte de production.
Inconsistent Feed Size for SAG/Ball Mills: Poorly controlled crusher product size leads to poor grinding circuit performance, higher energy consumption per ton, and reduced overall recovery rates.
Coûts opérationnels élevés: Premature wear on crusher components due to high silica content and abrasiveness drives up your cost per ton in replacement parts and labor.
Limites de capacité: An undersized or outdated primary crusher prevents you from scaling throughput to capitalize on highergrade ore bodies or optimized mine plans.
Safety Risks with Manual Adjustment: Traditional crushers requiring manual setting adjustment expose personnel to hazardous tasks near the crushing chamber.

Is your operation losing potential revenue due to unreliable crushing? Recherchez-vous une solution offrant un débit constant, reduces maintenance windows, and provides a predictable feed for downstream processes? The right primary gold ore crushing equipment is the foundational investment for plantwide efficiency.

2. APERÇU DU PRODUIT: CONCASSEUR À MÂCHOIRE PRIMAIRE POUR LE TRAITEMENT DU MINERAI D'OR

This heavyduty jaw crusher is engineered as the robust primary reduction unit for runofmine (ROM) minerai d'or. Il est conçu pour accepter de gros matériaux d'alimentation (généralement jusqu'à 80% of the gape dimension) et offrir une cohérence, coarse product for secondary crushing or direct feed to a grinding circuit.

Flux de travail opérationnel:
1. ROM gold ore is fed via dump truck or loader into the vibrating grizzly feeder (facultatif), which bypasses fines directly to the product belt.
2. Oversize material enters the deep crushing chamber of the jaw crusher, where a powerful elliptical motion compresses ore against a stationary jaw plate.
3. Le matériau broyé sort par une ouverture de décharge réglable, determining the product's top size.
4. Le produit concassé est acheminé vers l’étape suivante de votre usine de traitement des minéraux.

Champ d'application & Limites:
Portée: Idéal pour les durs, abrasive gold ores with high compressive strength and quartz content. Suited for stationary plants or semimobile setups. Effective in both greenfield projects and retrofit upgrades.
Limites: Not designed as a finecrushing unit. Requires competent feed regulation to prevent chamber packing. La taille maximale de l'alimentation est limitée par la dimension d'ouverture de la machine.
