1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous des opérations de récupération d’or alourdies par un débit incohérent, coûts d'entretien élevés, and regulatory compliance risks? Inefficient comminution directly impacts your bottom line through lost fine gold, consommation d'énergie excessive par tonne traitée, and unplanned downtime for liner changes and repairs. Considérez ces défis communs:
Pertes de récupération: Inadequate liberation of gold from quartz or sulfide matrices leads to significant value reporting to tailings.
Inefficacité opérationnelle: Alimentation manuelle, inconsistent particle size distribution, and frequent mechanical adjustments reduce plant throughput and increase labor costs.
High Lifetime Costs: Premature wear of grinding media and liners, coupled with high energy consumption per ton of ore, erodes project margins.
Conformité & Risques pour la sécurité: NonCE marked equipment introduces legal liabilities for EU operations and may lack integrated safety features, increasing operational risk.

Comment obtenir une cohérence, conforme, and costeffective ore reduction to optimize cyanidation or gravity recovery yields? The solution requires robust engineering designed for the specific abrasiveness and liberation characteristics of goldbearing ore.

2. APERÇU DU PRODUIT

Our CE Marked Stamp Mill is a modern interpretation of a proven technology, engineered for efficient gravity concentration circuits and precyanidation size reduction in small to mediumscale gold mining operations. It delivers controlled impact crushing through mechanized stamps to liberate gold from host rock.

Flux de travail opérationnel:
1. Alimentation contrôlée: Ore is introduced via a regulated feed hopper onto a durable mortar box.
2. Percussions mécaniques: Une série de timbres lourds soulevés mécaniquement (chaussures) are dropped in sequence onto the ore.
3. Progressive Liberation: L'impact répété fracture le minerai, progressively reducing it to a target slurry consistency.
4. Décharge de boue: The crushed slurry passes over an integrated discharge screen, ensuring optimal particle size reports to the subsequent concentration stage (par ex., secouer les tables, concentrateurs centrifuges).

Champ d'application & Limites:
Idéal pour: Minerais d'or en broyage libre, usines pilotes, remote operations with limited grid power, and operations prioritizing simplicity and robust mechanical design over ultrafine grinding.
Limites: Not suitable for primary crushing of large runofmine ore or for pulverizing refractory ores requiring sub100 micron particle sizes. Capacity is typically below that of highthroughput ball mill circuits.
