1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Êtes-vous confronté à des goulots d’étranglement persistants dans votre circuit de récupération de l’or ?? Inconsistent ore throughput, excessive liner and part wear, and unplanned maintenance downtime directly erode your profit margins. Each hour a stamp mill is offline for repairs or adjustment represents thousands in lost processing revenue. En outre, inefficient particle liberation can leave valuable gold locked in tailings, while high energy consumption per ton of ore processed squeezes operational budgets.

Are you asking how to:
Increase consistent throughput while managing variable ore hardness?
Reduce the frequency and cost of mechanical maintenance?
Improve overall recovery rates from complex ores?
Achieve predictable operating costs with lower energy consumption per ton?

A certified, modern stamp mill solution is engineered to address these exact operational challenges.

2. APERÇU DU PRODUIT

This certified stamp mill is a heavyduty, mechanized milling system designed for the reliable crushing and grinding of goldbearing quartz rock to liberate values for subsequent recovery processes. It operates on the proven principle of dropping heavy weights (timbres) sur du minerai introduit dans une boîte à mortier.

Flux de travail opérationnel:
1. Alimentation: Minerai brut ou minerai concassé primaire (<50mm) is continuously fed into the mortar box.
2. Pulvérisation: Mechanically lifted stamps are released in a controlled cycle, pulverizing the ore against a hardened die (mortar block) with repeated impact.
3. Laver & Décharge: A continuous water flow through the mortar box washes the finely ground pulp (boue) over an apron or through screens for discharge to downstream concentration (par ex., écluses, secouer les tables).

Champ d'application & Limites:
Portée: Ideal for small to mediumscale hard rock gold mining operations, usines pilotes, and processing centers handling quartzdominant ores. Effective for both freemilling and some refractory ores requiring fine grinding.
Limites: Not suitable for highclay or highly abrasive nongold ores without modification. Requires a consistent feed size and stable water supply. Operational noise and vibration necessitate proper site planning.
