1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Vos opérations de traitement de l’or sont-elles limitées par un concassage primaire inefficace ?? L’étape initiale de réduction de taille donne le ton à l’ensemble de votre circuit de récupération, and suboptimal performance here creates cascading losses. Les défis courants incluent:
Temps d'arrêt excessif: Frequent liner changes and unplanned maintenance in harsh gold ore environments halt your milling circuit, coûtant des milliers de dollars par heure en perte de production.
Taille d'alimentation incohérente: Poorly fragmented, slabby output from primary crushers leads to bridging in bins, reduced throughput in SAG mills, et finalement, lower gold recovery rates.
Coûts opérationnels élevés: Premature wear on crusher components due to abrasive quartz and sulfide minerals drives up your costperton metric for consumables like mantles, concaves, et plaques de mâchoire.
Inefficacité énergétique: Older crushing technology often requires more power to achieve the required reduction ratio, directly impacting your site’s energy budget.

Is your primary crushing circuit a bottleneck or a catalyst for profitability? The right heavyduty equipment is not an expense but a strategic investment in plant stability and metal recovery.

2. APERÇU DU PRODUIT

This content details our range of Stationary Primary Gyratory Crushers engineered specifically for hightonnage gold ore processing plants. These machines are designed for the first stage of comminution, accepting runofmine (ROM) nourrir directement de la mine.

Flux de travail opérationnel:
1. Minerai d'or ROM (jusqu'à 1500 mm) is fed into the crusher’s deep chamber via dump trucks or a primary feeder.
2. The eccentrically rotating mantle continuously compresses ore against the stationary concave, achieving progressive crushing.
3. Crushed material discharges via gravity through the bottom setting, producing a consistent product size typically between 150mm to 250mm for feed to secondary crushing or SAG mills.

Champ d'application: Ideal for largescale gold mining operations with annual throughput exceeding 5 millions de tonnes. Best suited for hard, minerais abrasifs (par ex., quartz vein hosted).
Limites: Not recommended for smallscale operations (<500,000 tpa) due to high capital cost and footprint. Requires stable concrete foundations and significant overhead clearance for maintenance.
