1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous des opérations de récupération d’or alourdies par un débit incohérent, excessive downtime for maintenance, et des coûts opérationnels croissants? Manual crushing and inefficient grinding directly impact your bottom line through lost production hours and suboptimal mineral liberation. Considérez ces défis communs:
Temps d'arrêt opérationnel élevé: Frequent breakdowns of undersized or poorly constructed equipment halt entire processing lines.
Libération d’or inefficace: Inconsistent particle size from primary crushing leads to poor amalgamation or leaching recovery rates.
Coûts de maintenance excessifs: Constant wear part replacement and unplanned repairs create unpredictable OPEX.
Limites d'évolutivité: Equipment cannot efficiently handle increased ore feed from expanded mining operations.
Intensité du travail & Safety Concerns: Reliance on manual processes for feeding and monitoring increases risk and labor costs.

La question centrale pour les directeurs d'usine est la suivante: comment pouvez-vous obtenir un, highvolume ore reduction with predictable maintenance schedules and optimized gold recovery? The industrialgrade stamp mill provides a proven, mechanical solution.

2. APERÇU DU PRODUIT

An industrial stamp mill for gold mining is a heavyduty mechanical crusher designed for the repetitive, highimpact crushing of goldbearing quartz rock. It operates on the camandlever principle to pulverize ore into fine sand, liberating gold particles for subsequent recovery processes like amalgamation or cyanidation.

Flux de travail opérationnel:
1. Alimentation: Runofmine (ROM) or primarily crushed ore is fed into a sturdy mortar box.
2. Écrasement: Une série de timbres lourds soulevés mécaniquement (chaussures) are dropped onto the ore via a rotating camshaft.
3. Pulvérisation: The continuous impact reduces the ore to a fine slurry or sand consistency.
4. Laver & Extraction: Water introduced into the mortar box washes the crushed material over an amalgamated copper plate or onto tables for concentration.

Champ d'application & Limites:
Portée: Idéal pour le hard rock (filon) gold mining operations processing quartz veins and sulphide ores. Highly effective as a primary or secondary crusher in small to mediumscale operations, remote sites, or as a backup system.
Limites: Ne convient pas aux soft, clayrich material without modification. Requires a consistent water source for optimal operation. Generally has a higher energyperton footprint than modern ball mills for very largescale, continuous operations.
