1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous des opérations de récupération d’or alourdies par un débit incohérent, temps d'arrêt excessif pour maintenance, et des coûts d'exploitation imprévisibles? Legacy crushing and grinding circuits often struggle with hard rock ores, leading to suboptimal liberation and gold losses in tailings. Les défis sont quantifiables: unplanned stoppages for liner changes and mechanical repairs, consommation d'énergie élevée par tonne traitée, and the constant labor required for manual operation and monitoring. These factors directly erode your profit margin. Is your current mineral processing equipment delivering the reliable, efficace, and costeffective performance required in today’s market? The solution lies in a purposeengineered ODM stamp mill designed for modern gold mining operations.

2. APERÇU DU PRODUIT

This product is a heavyduty ODM (Fabricant de conception originale) stamp mill engineered for the primary crushing and coarse grinding of goldbearing quartz rock and other ores. Its operational workflow is a proven, mechanically robust process:
1. Alimentation en minerai: Runofmine (ROM) ore is fed into a enclosed mortar box.
2. Écrasement & Affûtage: Timbres levés mécaniquement (heavy iron rods) sont libérés pour tomber sur le minerai, repeatedly pulverizing it through impact.
3. Formation de boue: Water is introduced to create a slurry of crushed material.
4. Décharge: The slurry passes through a perforated screen plate at the end of the mortar box, garantissant une taille de particule contrôlée.
5. Récupération d'or: The discharged slurry flows to downstream processes like sluices or amalgamation plates for gold concentration.

Application scope includes primary comminution for small to midscale hard rock gold mining operations, usines pilotes, et retraitement de sites historiques. It is particularly suited for vein material where freemilling gold is present. A key limitation is its relatively coarse grind compared to ball mills; it is typically deployed as a primary unit ahead of finer grinding or as a standalone solution where very fine liberation is not required.
