1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are your gold ore processing operations constrained by unreliable primary crushing? Taille d'alimentation incohérente, usure excessive de la doublure, and unplanned maintenance directly impact your mill throughput and recovery rates. Considérez ces défis communs:
Temps d'arrêt imprévus: Catastrophic failure of a critical crusher component can halt your entire processing line for days, coûtant des milliers de dollars par heure en perte de production.
Coûts d'exploitation élevés: Premature wear on manganese liners and frequent part replacements under abrasive gold ore conditions create a significant and recurring expense.
Bottlenecked Throughput: An undersized or inefficient primary crusher limits feed to your SAG/Ball mill circuit, capping your plant’s overall gold production capacity.
Incohérence du produit: Poorly controlled discharge sizing leads to inefficiencies downstream, affecting grinding circuit performance and ultimately, récupération.

Is your current gold ore crushing equipment a source of cost and complexity rather than a foundation for reliability? The solution requires machinery engineered not just to crush, mais endurer.

2. APERÇU DU PRODUIT

Our OEM factory specializes in the design and manufacture of heavyduty primary jaw crushers specifically configured for gold ore crushing applications. This equipment serves as the first critical stage in mineral liberation, reducing runofmine (ROM) ore to a consistent, taille gérable pour le traitement secondaire.

Flux de travail opérationnel:
1. Le minerai d'or ROM est introduit dans le chargeur vibrant pour grizzly (facultatif), qui contourne les matériaux sous-dimensionnés et dirige les matériaux surdimensionnés vers le concasseur.
2. Ore enters the robust crushing chamber of the jaw crusher, where a highpressure mechanical force is applied between a fixed and a moving jaw plate.
3. The compressive action breaks the ore along natural fissures and weaknesses.
4. Crushed material discharges through an adjustable gap at the bottom, déterminer la taille du produit final.
5. The crushed product is conveyed to the next stage of your beneficiation circuit.

Champ d'application & Limites:
Portée: Ideal for primary crushing of hard and abrasive gold ores (quartz, sulfures), including runofmine material with large feed sizes. Suited for both stationary plant installations and modular plant designs.
Limites: Not designed as a fine reduction or grinding machine. Maximum feed size is constrained by the specific model’s inlet dimensions. Performance is optimal with proper feed control to prevent choking.
