1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are your gold recovery operations hampered by inconsistent throughput, excessive downtime for liner replacement, and unpredictable maintenance costs? Les équipements de concassage et de broyage existants ne parviennent souvent pas à répondre aux exigences des technologies modernes., traitement du minerai à grand volume, leading to significant financial drain. Considérez ces défis communs:
Temps d'arrêt imprévus: Frequent breakdowns and the laborintensive process of replacing worn stamper shoes or dies halt your entire milling circuit.
Libération inefficace: Inconsistent particle size distribution from the stamping process can lock fine gold within larger ore fragments, réduire les taux de récupération globaux.
Coûts opérationnels élevés: Consommation d’énergie excessive par tonne de minerai traité, coupled with high wear part consumption, érode les marges bénéficiaires.
Limites d'évolutivité: Older stamp mill designs struggle to integrate with modern cyanidation or gravity concentration circuits, créer des goulots d'étranglement.

How do you increase throughput reliability while controlling the total cost of ownership for your primary crushing and grinding stage? The solution requires a reengineered approach to a proven technology.

2. APERÇU DU PRODUIT

The modern heavyduty stamp mill is a mechanized crushing system designed for the reliable reduction of goldbearing quartz ore. It functions as a primary crusher and grinder, delivering a consistent feed for secondary concentration processes.

Flux de travail opérationnel:
1. Présentation du flux: Runofmine ore is fed into a robust mortar box via a regulated feed system.
2. Mechanical Stamping: Une série de timbres lourds soulevés mécaniquement (marteaux) are released in sequence, dropping onto the ore bed within the mortar box.
3. Réduction du minerai: The impact and weight of the stamps crush and pulverize the quartz matrix, liberating gold particles.
4. Décharge de boue: Le matériau broyé est lavé à travers un tamis de décharge avec de l'eau, creating a slurry that reports to downstream gravity separation or leaching circuits.

Champ d'application & Limites:
Portée: Ideal for freemilling gold ores where the gold is liberated at coarse to medium grind sizes. Highly effective in remote operations due to mechanical simplicity and durability. Suited for both stationary plant installations and modular mining camps.
Limites: Less efficient for ultrafine grinding requirements compared to ball mills. Not optimal for complex refractory ores requiring finer liberation. Requires a consistent feed size to maintain optimal operation.
