H1: HauteCapacité, LowCostPerTon Gold Ore Crushing Solutions

1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Processing gold ore presents a distinct set of crushing challenges that directly erode profitability. Are you facing these costly operational realities?

Coûts d’abrasion élevés: The quartz and hard rock matrices common in gold ores rapidly wear crusher components, entraînant des changements fréquents de doublure, excessive spare parts inventory, et arrêts de maintenance imprévus.
Goulots d’étranglement du débit: Inconsistent feed size or capacity limitations in primary crushing stages constrain the entire milling circuit, leaving valuable tonnage—and revenue—unprocessed.
Intensité énergétique: Traditional crushing stages consume significant power. Inefficient comminution directly increases your highest variable cost: energy per processed ton.
Temps d'arrêt pour maintenance: Every hour a primary or secondary crusher is down for liner replacement or adjustment halts the entire processing plant, coûtant des milliers de dollars en perte de production.

La question centrale pour les directeurs d'usine est la suivante: How can you achieve the required particle reduction for optimal gold recovery while controlling wear costs, maximizing throughput uptime, and minimizing specific energy consumption? The answer begins with selecting the right sustainable gold ore crushing equipment.

2. APERÇU DU PRODUIT

This product line focuses on Primary Gyratory Crushers and Secondary Cone Crushers engineered specifically for the demands of hard rock gold ore processing. These machines form the critical first stages of size reduction, setting the foundation for downstream grinding and recovery efficiency.

Flux de travail opérationnel:
1. RunofMine (ROM) ore is fed into the primary gyratory crusher’s receiving hopper.
2. The gyrating mantle within the fixed concave crushes large rocks (souvent jusqu'à 1,5 m) against high pressure, reducing them to a manageable size (généralement 250 mm).
3. Crushed material is conveyed to a secondary cone crusher for further reduction to a finer product (généralement 50 mm), optimized for feed to SAG or ball mills.
4. The precisely controlled discharge setting ensures a consistent product size, improving overall circuit stability and recovery rates.

Champ d'application & Limites:
Portée: Ideal for medium to hightonnage hard rock gold operations (2,000+ DPT). Effective on lode ore, vein material, and oxidized deposits with high compressive strength.
Limites: Not suitable for clayrich or highly weathered alluvial deposits where alternative crushing methods may be preferred. Requires stable foundational support and controlled feed systems for optimal operation.
