1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you facing persistent challenges in your primary gold ore processing circuit? The limitations of traditional comminution and liberation methods directly impact your bottom line. Considérez ces obstacles opérationnels courants:
Low Gold Recovery Rates: Inefficient liberation of gold from quartz or sulfide matrices, leaving payable values in your tailings.
Temps d'arrêt opérationnel élevé: Frequent maintenance stops due to the abrasive nature of ore, wearing out components and halting production.
Consommation d'énergie excessive: Older crushing and grinding methods consuming disproportionate power per ton of ore processed.
Débit incohérent & Grade Control: Difficulty maintaining a steady, fine grind size essential for optimal cyanidation or gravity recovery.
Coût total de possession élevé: The cumulative cost of replacement parts, labor for repairs, and energy outweighing the initial equipment savings.

Is your operation sacrificing recovery and profitability due to an inefficient primary grinding solution? The right industrial stamp mill for gold mining addresses these exact pain points.

2. APERÇU DU PRODUIT

Our heavyduty stamp mill is a mechanized gravitydriven crushing mill designed for the primary liberation of gold from hard rock ore. It functions as a reliable, highimpact pulverizer, ideal for operations where simplicity, durabilité, and coarse to mediumfine grinding are priorities.

Flux de travail opérationnel:
1. Alimentation: Runofmine or primary crushed ore (<50mm) is fed into a sealed mortar box.
2. Écrasement & Affûtage: Timbres levés mécaniquement (5002000+ livres chacun) sont déposés séquentiellement sur le minerai, le pulvérisant par impacts répétés.
3. Laver & Décharge: A continuous flow of water washes the finely crushed slurry through a perforated plate (écran), discharging it for subsequent concentration.

Champ d'application & Limites:
Idéal pour: Processing freemilling gold ores, usines pilotes, small to mediumscale operations, and regions with limited grid power or technical infrastructure. Effective as a primary grinder ahead of shaking tables or centrifugal concentrators.
Limites: Ne convient pas au broyage ultrafin (100 DPT). Requires competent foundation design due to dynamic loads.

3. CARACTÉRISTIQUES PRINCIPALES
