1. ABERTURA ACIONADA POR PAINPOINT

Suas operações de recuperação de ouro estão limitadas pela britagem e moagem primária ineficientes?? Fábricas de carimbos antigas e equipamentos subdimensionados criam gargalos persistentes que impactam diretamente seus resultados financeiros. Considere estes desafios comuns:
Altos custos operacionais: Consumo excessivo de energia por tonelada de minério processado, coupled with frequent maintenance cycles for worn stamper heads and dies, corrói as margens de lucro.
Libertação Inconsistente: Poorly calibrated impact forces fail to achieve optimal particle size liberation, causing valuable gold to remain locked in waste rock and reducing overall recovery rates.
Tempo de inatividade excessivo: Mechanical failures in the cam and lift mechanism lead to unplanned shutdowns, halting your entire processing circuit and delaying production targets.
Limitações de escalabilidade: Traditional singlestamp setups cannot efficiently scale to match increased feed from modern excavation without multiplying footprint and operational complexity.
Intensidade de Trabalho: Manual feeding and discharge regulation, along with constant mechanical adjustment, require skilled attention that could be deployed elsewhere.

Is your operation achieving maximum yield from your ore? Can you reduce energy and maintenance costs while increasing throughput reliability? The solution lies in modernizing your primary reduction stage.

2. VISÃO GERAL DO PRODUTO: MODERN HEAVYDUTY STAMP MILL FOR GOLD ORE PROCESSING

Esta linha de produtos compreende serviços pesados, mechanized stamp mills engineered for the primary crushing and coarse grinding of goldbearing quartz rock. Designed as a core component for small to midscale hard rock mining operations or as a supplemental unit for pilot plants, isso transforma runofmine (ROM) ore into a granular feed suitable for secondary milling or direct cyanidation leaching.

Fluxo de Trabalho Operacional:
1. Alimentação controlada: Minério ROM (typically ≤6” diameter) is conveyed into a sealed feed hopper with a regulated gate to control flow.
2. Reciprocating Impact: A series of mechanically lifted, heavy cast iron or steel stamps (sapato) are dropped in sequence onto anvils (morre) within a mortar box, delivering controlled, highimpact force.
3. Continuous Pulverization: Ore is crushed by repeated impact. Water introduced into the mortar box creates a slurry that passes through a discharge screen.
4. Classificação & Descarga: Crushed material meeting the target size exits via the screen; oversized particles remain in the mortar box for further impact.

Escopo de aplicação & Limitações:
Ideal para: Freemilling gold ores where cyanidation follows crushing; processing quartz, veio, or vein material; operações que exigem robustez, mechanically simple comminution.
Limitações: Não é adequado para macio, minérios ricos em argila que causam empacotamento; less energyefficient than some modern ball mills for fine grinding; requires firm foundation due to vibrational forces.
