1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous une opération de traitement de l'or où l'alimentation en minerai est incohérente, temps d'arrêt excessif pour les changements de revêtement, and rising energy costs are eroding your profit margins? Each hour your primary grinding circuit is offline for maintenance represents a direct loss in throughput and revenue. The challenge of achieving consistent, fine liberation of goldbearing minerals without incurring prohibitive operational expenses is a constant pressure.

Considérez ces obstacles opérationnels courants:
Temps d'arrêt pour maintenance élevé: Frequent shutdowns to replace worn stamp mill shoes, meurt, and liners disrupt continuous processing schedules.
Utilisation inefficace de l’énergie: Older or poorly calibrated stamp mills consume disproportionate power per ton of ore crushed, impactant directement les coûts d’exploitation.
Taille du produit incohérente: Variable feed size or wear on components leads to unevenly crushed material, compromising downstream recovery in cyanidation or gravity circuits.
Travail élevé & Coûts de sécurité: Manual monitoring and mechanical adjustments increase labor overhead and potential safety exposure around heavy moving parts.
Limites d'évolutivité: Inflexible designs struggle to adapt to varying ore hardness or increased plant capacity targets.

What if your primary crushing stage could deliver more reliable performance with predictable maintenance intervals and lower cost per ton? La solution réside dans la modernisation, precisionengineered stamp mill technology.

2. APERÇU DU PRODUIT

The ODM Stamp Mill is a modern reinterpretation of the proven camandlever crushing principle, engineered for reliable primary crushing of goldbearing quartz ores. Il est conçu comme un robuste, lowspeed impact crusher where mechanically lifted heavy stamps (marteaux) are dropped onto ore fed into a mortar box, fracturer le matériau par des impacts répétés.

Flux de travail opérationnel:
1. Présentation du flux: Runofmine (ROM) ore is consistently fed into the stamp mill’s mortar box via a regulated feeder.
2. Cyclic Crushing: The rotating camshaft lifts multiple cast iron or steel stamps in sequence, releasing them to fall under gravity onto the ore.
3. Réduction des particules: Ore is fractured by direct impact and grinding between the stamp shoe and the die (mortar box base).
4. Décharge de boue: Crushed material exits through a screen grate at the front of the mortar box, mélangé à de l'eau pour former une bouillie destinée au transport vers un traitement secondaire.

Champ d'application & Limites:
Idéal pour: Freemilling gold ores where coarse gold liberation is required; opérations à petite et moyenne échelle (1100 DPT); regions with stable but limited power availability; operations prioritizing mechanical simplicity and durability.
Limites: Ne convient pas aux sols mouillés, sticky clay ores that cause packing; less energyefficient than some modern ball mills for fine grinding; requires firm foundation due to dynamic loads.
