1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you facing persistent bottlenecks in your gold processing circuit due to inefficient primary grinding? The performance of your initial size reduction stage directly dictates downstream recovery rates and overall plant profitability. Common challenges with conventional primary crushing and grinding setups include:

Temps d'arrêt opérationnel élevé: Frequent liner changes and mechanical failures in jaw crushers or primary ball mills lead to unscheduled stoppages, costing hundreds of production hours annually.
Suboptimal Liberation: Inconsistent feed size from primary processing can cause poor gold particle exposure, trapping valuable material in waste rock and reducing overall cyanidation or gravity recovery yields by 515%.
Consommation d'énergie excessive: Plus vieux, oversized primary milling equipment operates at low efficiency, with a significant portion of input power converted to heat and noise rather than productive grinding work.
High Maintenance Labor Costs: The arduous, manual task of maintaining heavyduty primary crushers consumes skilled labor hours and increases safety exposure for your crew.

Is your operation sacrificing gold recovery and margin due to an unreliable or inefficient primary size reduction system? The solution lies in selecting the right foundational technology for consistent, controllable feed preparation.

2. APERÇU DU PRODUIT

The Chinese Stamp Mill is a modern reinterpretation of a historically proven principle, engineered for robust primary crushing and coarse grinding in gold mining applications. This gravitydriven hammer mill is designed as a reliable, lowercapacity alternative or supplement for processing goldbearing quartz rock at the head of a milling circuit or within smallscale/artisanal operations.

Flux de travail opérationnel:
1. Présentation du flux: Runofmine (ROM) or primarily crushed quartz ore (typiquement <50mm) is fed into a vertical guide box.
2. GravityDriven Impact: A series of mechanically lifted heavy stamps (wooden or metal rods shod with iron shoes) are released to drop onto the ore bed contained within a mortar box.
3. Réduction des particules: The repeated impact of the stamps fractures the ore through sheer force, progressively reducing it to a coarse sand consistency.
4. Formation de boue & Décharge: L'eau est introduite dans la boîte à mortier, creating a slurry that passes through a fine screen at the discharge end. Oversize material remains for further crushing, while the liberated slurry reports to downstream concentration (par ex., écluses, secouer les tables).

Champ d'application & Limites:
Idéal pour: Smalltomedium scale operations, usines pilotes, toll processing centers, or remote sites with limited access to grid power or complex maintenance infrastructure. Effective on freemilling gold ores hosted in brittle quartz matrices.
Limites: Ne convient pas aux opérations à fort tonnage (>50 TPD typically). Less effective on clayrich, mouillé, or highly ductile ores that absorb impact energy. Requires consistent ore feed size for optimal operation.

3. CARACTÉRISTIQUES PRINCIPALES
