1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you managing a small to midscale gold operation where inefficient primary ore crushing and grinding is constraining your entire production circuit? Alimentation manuelle, inconsistent particle size distribution, and excessive downtime for liner changes directly impact your recoverable ounces and profitability. Each hour of mill stoppage can represent thousands in lost revenue, while poor liberation leads to gold reporting to tailings. Êtes-vous actuellement confronté: high perton processing costs due to low throughput; unpredictable maintenance cycles disrupting production schedules; or safety risks associated with manual handling of ore and grinding media? Un moderne, engineered sustainable stamp mill addresses these core operational challenges by providing reliable, mechanized comminution designed for continuous, costeffective operation.

2. APERÇU DU PRODUIT

Ce produit est un moderne Sustainable Stamp Mill, a mechanized mineral processing system engineered for the primary crushing and grinding of goldbearing quartz ores. It is designed for operations requiring a robust, relatively simple comminution circuit with lower capital expenditure than highspeed ball mills.

Flux de travail opérationnel:
1. Alimentation: Runofmine (ROM) ore is consistently fed via a regulated hopper and conveyor into the mortar box.
2. Écrasement & Affûtage: Timbres levés mécaniquement (46 per unit) sont déposés séquentiellement sur le minerai, combining impact and slight abrasion to fracture the material.
3. Classification & Décharge: Pulverized material passes through a perforated screen plate at the mortar box discharge, with slurry flowing to downstream concentration processes (par ex., écluses, secouer les tables).
4. Intégration de l'eau: A controlled water wash facilitates material transport through the mill and aids in initial gravity separation.

Champ d'application & Limites:
Portée: Ideal for freemilling gold ores where gravity recovery is effective; suitable for remote locations with intermittent power; excellent for pilot plants or operations processing 50500 tonnes par jour.
Limites: Not optimal for refractory ores requiring fine grinding or chemical leaching as a primary method; lower energy efficiency per ton compared to advanced roller mills at very high throughputs; requires competent foundation due to dynamic loads.

3. CARACTÉRISTIQUES PRINCIPALES
