Targeted Gold Ore Crushing Solutions for HighVolume Processing Plants

Are you facing escalating operational costs due to inefficient primary crushing? Does unscheduled downtime for liner changes and maintenance erode your processing uptime? Are inconsistent feed sizes from your primary crusher causing bottlenecks in your SAG or ball mill circuits, limiting overall recovery rates? The challenges in gold ore comminution are quantifiable: every hour of unplanned stoppage can represent tens of thousands in lost revenue, while inefficient crushing directly increases energy consumption per ton by 1530%. Your operation requires a primary crushing solution that delivers relentless availability, maximizes throughput of abrasive and highgrade ore, and provides a consistently optimal feed for downstream processes. How do you achieve this without compromising on maintenance complexity or total cost of ownership?

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

Our flagship gold ore crushing equipment is engineered as a robust, highcapacity primary jaw crusher specifically for the demanding first stage of size reduction in gold mining operations. It is designed to process runofmine (ROM) gold ore with high compressive strength and variable moisture content, delivering a consistent product size for secondary crushing or direct feed to milling circuits.

Flux de travail opérationnel:
1. Consommation alimentaire: Minerai ROM (jusqu'à 1200 mm) est introduit dans la mangeoire vibrante pour grizzlis (VGFF VGF), qui scalpe les matériaux fins et dirige les matériaux surdimensionnés vers le concasseur.
2. Concassage primaire: The core jaw crusher utilizes a steep nip angle and aggressive crushing action to fracture the ore between a fixed and a moving jaw plate.
3. Décharge du produit: Le matériau broyé sort par un réglage de décharge réglable, ensuring precise control over product top size (typically 150mm to 250mm).
4. Transport de matériel: The crushed product is conveyed to the next stage of your mineral processing plant.

Champ d'application & Limites:
Portée: Idéal pour les stations de concassage primaire stationnaires, largescale openpit or underground mining operations processing hard rock gold ores (par ex., veines de quartz, minerais sulfurés). Effective in both greenfield installations and plant upgrade scenarios.
Limites: Non conçu comme une solution autonome pour le broyage complet d'un circuit; requires integration with secondary/tertiary crushers or mills for final liberation. La taille et la capacité maximales de l'alimentation dépendent du modèle.

Scénarios d'application

HighGrade Underground Mine Expansion

Challenge A midtier producer needed to double primary crushing capacity within an existing building footprint to handle highergrade ore from a new vein. Space constraints ruled out additional conventional crushers.
Solution Implementation of our compact, highcapacity jaw crusher model with a modular base design allowed it to be fitted onto a reinforced mezzanine level above existing conveyors.
Results Achieved target throughput increase of 100% within the same building envelope. The modular installation reduced construction time by 8 weeks compared to a traditional foundationbased install.

Remote OpenPit Operation with Abrasive Ore

Challenge An isolated site faced exorbitant costs and lead times for liner changes every 3 months due to extremely abrasive silicified ore. Downtime logistics crippled annual throughput targets.
Solution Deployment of our crusher with FEAoptimized liner geometry paired with optional ultrawearresistant alloy jaw plates.
Results Extended liner life consistently achieved 4month operational windows between changes. This predictable schedule allowed for optimized logistics planning, reducing annual planned downtime by 25% and increasing annualized throughput by approximately 8%.
