1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous une opération de traitement de l'or où les taux de production et de récupération sont sous pression constante ?? The limitations of traditional comminution and liberation methods directly impact your bottom line. Considérez ces défis communs:
Inconsistent Particle Liberation: Inefficient crushing leads to poor gold exposure, trapping valuable material in waste rock and reducing overall recovery.
Temps d'arrêt opérationnel élevé: Frequent maintenance cycles on stamp mills, driven by wear and mechanical stress, halt your processing line and delay production targets.
Consommation d'énergie excessive: Older stamp mill designs operate with poor energy efficiency, translating to unsustainable power costs per ton of ore processed.
Limites d'évolutivité: Rigide, singlecapacity systems cannot adapt to varying ore grades or feed rates without significant reengineering or capital expenditure.
Environnemental & Noise Control Costs: Managing dust, vibration, and noise to meet regulatory standards adds complexity and expense to plant operations.

How can you achieve more consistent mineral liberation with lower operating costs and improved uptime? The solution lies in modernizing your core crushing process with a highquality stamp mill engineered for today’s demands.

2. APERÇU DU PRODUIT

Cette gamme de produits comprend des véhicules lourds, modernized moulins à timbres for primary and secondary crushing of goldbearing ore. Designed for small to midscale mining operations and pilot plants, this equipment delivers the proven percussive crushing action of traditional stamps with enhanced reliability and control.

Flux de travail opérationnel:
1. Présentation du flux: Runofmine (ROM) ore is fed into a secure feed hopper, regulating flow to the mortar box.
2. Concassage percussif: Timbres levés mécaniquement (cams or pistons) drop onto the ore in the mortar box, applying repeated highimpact force to fracture the material.
3. Formation de boue & Décharge: Crushed ore mixes with water in the mortar box, forming a slurry that passes through a discharge screen, ensuring controlled particle size before proceeding to concentration (par ex., écluses, tableaux).

Champ d'application & Limites:
Idéal pour: Minerais d'or en broyage libre, pilot plant testing, fonctionnement avec alimentation intermittente, and regions where robust, mechanical simplicity is preferred over complex circuitry.
Limites: Ne convient pas au broyage ultrafin (requires secondary ball milling), highly abrasive ores without specific liner configurations, or fully automated plants requiring continuous closedcircuit comminution.
