1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Êtes-vous confronté à des goulots d’étranglement persistants dans votre circuit de récupération de l’or ?? The crushing and grinding stage is often the source of significant operational and financial drag. Les défis courants liés aux opérations des usines de tamponnage conventionnelles comprennent:

Temps d'arrêt excessif pour la maintenance: Changements fréquents de doublure, usure de l'arbre à cames, and die replacements halt production for days, directly impacting your monthly ounce count.
Taille de mouture incohérente & Gold Loss: Uneven particle size distribution from worn components can lead to poor liberation, causing valuable fine gold to report to tailings or become trapped in coarse concentrate.
Coûts opérationnels élevés: Significant energy consumption per ton of ore processed, coupled with high labor requirements for manual feeding and monitoring, érode les marges bénéficiaires.
Environnemental & Safety Concerns: Dust generation at the feed point and high noise levels create compliance hurdles and increase site risk profiles.

Is your operation sacrificing recovery rates and profitability due to an inefficient primary grinding solution? What if you could modernize your comminution process with a stamp mill engineered for the demands of today’s commercial gold mining?

2. APERÇU DU PRODUIT: HEAVYDUTY MODERN STAMP MILL

Le [Série fabricant/modèle] Professional Stamp Mill is a purposebuilt gravityimpact crushing and grinding machine designed for the reliable, costeffective liberation of gold from quartz ore and sulfides. It serves as a robust primary grinder, particularly suited for small to midscale operations or as a satellite mill for specific highgrade veins.

Flux de travail opérationnel:
1. Alimentation contrôlée: Ore (typiquement <2") is fed via a regulated hopper and conveyor into the mortar box.
2. Impact dû à la gravité: Une série de timbres lourds soulevés mécaniquement (5002000 livres chacun) sont déposés séquentiellement sur le lit de minerai, pulvériser un matériau par impact répété.
3. Décharge continue: Crushed material passes through a perforated discharge diaphragm, mixed with water to form a slurry that reports to downstream concentration (par ex., secouer les tables, concentrateurs centrifuges).

Champ d'application & Limites:
Idéal pour: Hard rock gold ores (quartz), usines pilotes, remote operations with limited power infrastructure, and operations prioritizing mechanical simplicity and durability over ultrafine grinding.
Limites: Ne convient pas aux soft, minerais riches en argile qui provoquent un tassement. Achieves a typical grind size of 2060 engrener; secondary milling may be required for ultrafine gold or refractory ores.
