1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous des opérations de récupération d’or alourdies par un débit incohérent, coûts d'entretien excessifs, et une libération minérale sous-optimale? Legacy crushing and grinding circuits can create significant bottlenecks, ayant un impact direct sur vos résultats. Considérez ces défis communs:
Pertes de récupération: Inefficient particle size reduction fails to fully liberate gold from complex ores, laisser des matériaux précieux dans les résidus.
Temps d'arrêt imprévus: Frequent breakdowns of underengineered stamp mills or primary crushers halt entire processing lines, coûtant des milliers de dollars par heure en perte de production.
Coûts opérationnels élevés: Consommation d’énergie excessive par tonne traitée, coupled with high wear part replacement frequency and laborintensive operation, érode les marges bénéficiaires.
Sortie incohérente: Variable feed size or hardness leads to fluctuating grind coarseness, complicitating downstream cyanidation or gravity recovery processes.

Is your operation seeking a reliable, highcapacity solution to achieve consistent, optimal grind size for maximum gold recovery? The industrial stamp mill remains a proven technology for specific applications, and modern importers provide advanced models designed to address these exact pain points.

2. APERÇU DU PRODUIT

The Industrial Stamp Mill is a heavyduty mechanical crushing device designed for the coarse to intermediate grinding of goldbearing quartz rock and other ores. Its core function is to liberate gold particles through repeated percussive action, preparing material for subsequent fine grinding or direct chemical processing.

Flux de travail opérationnel:
1. Présentation du flux: Runofmine (ROM) ore or primarycrushed rock is fed into a sturdy mortar box.
2. Concassage percussif: A set of mechanically lifted heavy stamps (weighted rods with hardened shoes) are alternately dropped onto the ore bed.
3. Classement des tailles: Crushed material passes through a screen grate at the mortar box discharge; oversized particles remain for further crushing.
4. Décharge de boue: Finer material exits as a slurry, typically directed to shaking tables or fine grinding circuits for further concentration.

Champ d'application & Limites:
Idéal pour: Minerai d'or en roche dure (quartz), usines pilotes, opérations à petite et moyenne échelle (50500 DPT), and regions with limited access to complex milling technology.
Limites: Not suitable for soft or clayrich ores (causes packing), requires consistent feed sizing (<2"), generally less energyefficient than modern ball mills for highvolume fine grinding.
