1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous une opération de traitement de l'or dont le débit, taux de récupération, et les coûts opérationnels sont sous pression constante? The performance of your comminution circuit directly impacts your bottom line. 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 mortar box repairs lead to significant production halts.
Mouture incohérente & Mauvaise libération: Uneven particle size distribution from worn stamps or irregular feed can trap valuable gold within larger ore particles, reducing overall recovery in downstream processes like cyanidation or gravity concentration.
Coûts opérationnels élevés: Consommation d’énergie importante par tonne de minerai traité, couplé à des exigences de main d’œuvre élevées pour l’alimentation et la surveillance manuelles, érode les marges bénéficiaires.
Limites d'évolutivité: Traditional designs often struggle with efficient throughput increases without major footprint expansion or duplicate mill installations.

How do you increase tonnage and improve gold liberation while controlling maintenance overhead and energy use? The solution requires a modernized approach to a proven technology.

2. APERÇU DU PRODUIT

Our White Label Stamp Mill is a modernized, heavyduty gravitydriven crushing mill engineered for the reliable comminution of goldbearing ores. It is designed as a core component for small to midscale processing plants, pilot operations, and heritage sites requiring robust, understandable technology.

Flux de travail opérationnel:
1. Alimentation contrôlée: Ore is consistently fed via a regulated conveyor or feeder into the mortar box.
2. Concassage par gravité: Des tampons levés mécaniquement sont libérés pour tomber sur le minerai, utilizing kinetic energy for fracture.
3. Décharge continue: Crushed material passes through a perforated screen plate at the mortar box end, garantir une taille de produit contrôlée.
4. Transport de lisier: The discharged pulp is typically directed to gravity concentration tables or a leaching circuit for gold recovery.

Champ d'application & Limites:
Idéal pour: Minerais d'or en broyage libre, matériau de veine de quartz, essais en usine pilote, and operations in regions with limited access to complex technical support or unstable power grids.
Mieux adapté à: Smalltomedium scale operations processing 50500 tonnes par jour.
Limites: Not optimal for very hard, minerais abrasifs (par ex., sulfures) without significant wear considerations. Nécessite une taille d'alimentation constante (typiquement 2" alimentation) pour un fonctionnement optimal.
