1. Addressing Core Operational Challenges in Primary Crushing

Is your primary crushing circuit the bottleneck in your gold recovery operation? The initial reduction of runofmine (ROM) ore sets the tone for your entire processing plant. Les inefficacités ici se répercutent en aval, impactant directement le débit, taux de récupération, and operating costs. Les principaux défis comprennent:

Temps d'arrêt excessif pour la maintenance: Frequent liner changes and unplanned repairs on crushers handling abrasive gold ore with high silica content (quartz) lead to significant production losses.
Taille d'alimentation incohérente & Fluctuations de capacité: Variable ore hardness and clay content cause feed choking or idle running, preventing your équipement de concassage de minerai d'or from operating at its designed capacity and increasing energy cost per ton.
Coûts élevés des pièces d’usure: The abrasive nature of goldbearing rock accelerates wear on mantles, concaves, et plaques de mâchoire, creating a substantial recurring expense in both parts inventory and labor.
Poorly Optimized Product Size: An incorrectly sized product from the primary stage overloads secondary crushers or grinding mills, reducing overall circuit efficiency and increasing power consumption.

Are you evaluating solutions that offer greater reliability, calendriers de maintenance prévisibles, and a lower total cost of ownership for your primary crushing station?

2. Présentation du produit: Concasseur à mâchoires primaire robuste pour le minerai d'or

Cette gamme de produits comprend une gamme de robustes, stationary and modular primary jaw crushers engineered specifically for the demanding first stage of concasseur de minerai d'or. Built to withstand the impact and abrasion of ROM feed, this equipment is the cornerstone of a highavailability comminution circuit.

Flux de travail opérationnel:
1. Minerai ROM (jusqu'à 80% de l'ouverture d'alimentation du broyeur) is delivered via dump truck or loader into a vibrating grizzly feeder (VGFF VGF).
2. The VGF removes fines and directs oversize material into the crusher’s chamber.
3. A highinertia flywheel drives an eccentrically moving jaw, applying compressive force to fracture the ore against a fixed jaw.
4. Crushed material discharges onto the main product conveyor, while scalped fines bypass the crusher for optimal efficiency.
5. The resulting product (généralement 150 mm à 250 mm) is conveyed for secondary crushing or stockpiling.

Champ d'application: Ideal for hardrock gold deposits (minerais filoniens), comme ceux contenant des veines de quartz. Suitable for both greenfield installations and retrofit projects aiming to upgrade existing capacity.

Limites: Not designed as a standalone solution for alluvial/placer deposits requiring scrubbing and screening only. Feed must be properly prepared to remove tramp metal; an integrated protection system is recommended.
