1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

¿Está usted gestionando operaciones de recuperación de oro agobiadas por un rendimiento inconsistente?, excessive maintenance downtime, y costos operativos impredecibles? Legacy crushing and grinding circuits often struggle with hard rock ores, leading to suboptimal liberation and gold losses in tailings. Los desafíos son cuantificables: unplanned stoppages for liner changes and mechanical repairs, Alto consumo de energía por tonelada procesada., 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, eficiente, and costeffective performance required in today’s market? The solution lies in a purposeengineered ODM stamp mill designed for modern gold mining operations.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

This product is a heavyduty ODM (Fabricante de diseño original) 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. Ore Feeding: Runofmine (memoria de sólo lectura) ore is fed into a enclosed mortar box.
2. Aplastante & Molienda: Sellos levantados mecánicamente (heavy iron rods) se liberan para caer sobre el mineral, repeatedly pulverizing it through impact.
3. Formación de lodo: Water is introduced to create a slurry of crushed material.
4. Descargar: The slurry passes through a perforated screen plate at the end of the mortar box, asegurando un tamaño de partícula controlado.
5. Gold Recovery: 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, plantas piloto, y reprocesamiento de sitios históricos. 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.
