1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Êtes-vous confronté à des goulots d’étranglement persistants dans votre circuit de récupération de l’or ?? Inefficient comminution directly impacts your bottom line through excessive energy consumption, high media and liner wear costs, and suboptimal mineral liberation that locks away recoverable gold. Plant managers and engineering contractors understand that the stamp mill, while historically significant, often presents modern operational challenges: inconsistent particle size distribution leading to poor cyanide or gravity recovery rates, high mechanical maintenance downtime, and limited throughput scalability. How do you upgrade your primary crushing and grinding stage to achieve higher recovery yields without a complete plant overhaul? The solution lies in a modernized Service de conception d'exploitation minière d'or de broyeur de timbres en Chine, which reengineers this proven concept for contemporary efficiency and reliability.

2. APERÇU DU PRODUIT

Our service provides a comprehensive engineering design package for modernized gold ore stamp mills. We deliver customdesigned, heavyduty stamp batteries for the crushing and coarse grinding of goldbearing quartz ores, particularly suited for small to mediumscale operations or specific circuits within larger plants. The operational workflow is engineered for robustness: (1) Ore is fed into a rugged mortar box; (2) Timbres lourds levés mécaniquement (chaussures) are released in a controlled cycle to drop onto the ore; (3) The repetitive impact and slight sliding motion fractures the ore along grain boundaries; (4) Pulverized material is washed across an integrated perforated plate or through a screen; (5) The slurry reports to downstream concentration processes like shaking tables or centrifugal concentrators. This solution is specifically applicable for freemilling ores where coarse gold liberation is critical. It is less suited for finely disseminated ores requiring ultrafine grinding or for operations with stringent, largevolume throughput requirements exceeding several hundred tons per day.

6. SCÉNARIOS D'APPLICATION

SmallScale Gold Mining Cooperative (Afrique de l'Ouest) | Défi: Reliance on manual pounding mills resulted in low daily throughput (<0.5 ton/day) and significant gold losses in coarse tailings due to incomplete liberation. Solution: Implementation of a compact twobattery modern stamp mill design with integrated roughing shaking table. Résultats: Le débit a augmenté à 4 tons/day with a measured recovery rate improvement from ~40% to over 75%. Payback period was achieved within 8 mois d'exploitation.

Historic Mine Tailings Reprocessing Project (Latin America) | Défi: Existing tailings contained coarse gold locked in quartz fragments; traditional ball milling was costprohibitive due to lowgrade material volume. Solution: A customdesigned threebattery stamp mill circuit was deployed as the primary grinder ahead of centrifugal concentrators. Résultats:The stamp mill's selective fracturing characteristic efficiently liberated gold without overgrinding,facilitating processing of over 50 tons/day at an operating cost reduction of approximately35% comparedtoa full ball mill circuit.
