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 inefficient particle liberation? Outdated or poorly designed comminution equipment directly impacts your bottom line through excessive energy consumption, unplanned downtime for liner and part replacement, and suboptimal gold recovery rates. Considérez ces défis communs:
Coût opérationnel élevé: Inefficient grinding and crushing can consume disproportionate energy per ton of ore processed.
Temps d'arrêt fréquents: Traditional stamp mills with inferior metallurgy require frequent shutdowns for maintenance, arrêter toute votre chaîne de traitement.
Pertes de récupération: Inadequate or inconsistent particle size reduction fails to fully liberate gold from host rock, provoquant le dépôt de matières précieuses dans les résidus.
Problèmes d'évolutivité: Manual operation and control in remote locations limit your ability to efficiently scale output with feedstock variability.

La question centrale pour les directeurs d'usine est la suivante: comment pouvez-vous obtenir un, highvolume ore reduction with lower operational expenditure and maximized mineral liberation? The solution lies in modern, heavyduty stamp mill technology engineered for the specific demands of gold mining.

2. APERÇU DU PRODUIT

Cette gamme de produits comprend des véhicules lourds, mechanized stamp mills designed for the primary crushing and fine grinding of goldbearing ores. Conçu pour un fonctionnement continu dans des environnements exigeants, these mills transform runofmine (ROM) ore into a finely ground slurry optimized for subsequent cyanidation or gravity recovery processes.

Flux de travail opérationnel:
1. Alimentation: Minerai calibré (typiquement 2" à 3") is continuously fed into the mortar box via a regulated feed system.
2. Écrasement & Affûtage: Une série de timbres lourds soulevés mécaniquement (410 par moulin) are alternately dropped onto the ore within the mortar box, appliquer une force d'impact répétitive.
3. Pulvérisation & Laver: The impact reduces ore particles; a continuous water flow through the mortar box creates a slurry that passes through a discharge screen, garantissant une taille de particule contrôlée.
4. Décharge: The ground slurry exits for further processing (par ex., tables de fusion, réservoirs de lixiviation).

Champ d'application: Ideal for small to mediumscale hard rock gold mining operations, usines pilotes, and specialized processing circuits requiring a robust mechanical crusher/grinder. Effective on quartz veins and other brittle ores.

Limites: Moins adapté aux opérations à très fort tonnage (>500 DPT) where ball mills or SAG mills are standard, or for clayrich, plastic ores that may cause packing in the mortar box.
