1. ABERTURA ACIONADA POR PAINPOINT

Are you managing a gold processing operation where inconsistent throughput, altos custos de manutenção, and unpredictable recovery rates are eroding your margins? Key operational challenges with traditional comminution and liberation circuits include:

Tempo de inatividade excessivo: Unplanned stoppages for liner changes and mechanical repairs can halt your entire milling circuit for 824 horas, custando milhares em perda de produção por evento.
Moagem inconsistente & Pobre Libertação: Variable feed size and worn components lead to an uneven grind. Insufficient liberation of gold from host rock directly caps your recovery rate, deixando material valioso nos rejeitos.
Altos gastos operacionais: Consumable wear parts (forros, sapato, morre), alto consumo de energia por tonelada processada, and laborintensive operation create a significant ongoing cost burden.
Ambiental & Riscos de conformidade de segurança: Dust generation, slurry spillage, and noise levels present ongoing challenges for meeting ISO 14001 and OHSAS 45001 padrões, risking fines and operational licenses.

Is your current stamp mill or primary crusher delivering the predictable, costeffective performance required for profitable gold extraction? The solution lies in precisionengineered equipment designed for reliability and optimal mineral liberation.

2. VISÃO GERAL DO PRODUTO

The ISO Certified Stamp Mill is a modern reinterpretation of a proven technology, engineered for efficient gold ore processing in mediumscale operations. It functions as a core component for primary crushing and coarse grinding, facilitating the initial liberation of freemilling gold.

Fluxo de Trabalho Operacional:
1. Introdução ao feed: Runofmine (ROM) ore is fed into a robust hopper, regulating flow onto the feed table.
2. Percussão Mecânica: Selos Camdriven (or hammers) are lifted in sequence and dropped onto the ore placed on a durable die shoe/block assembly.
3. Redução de Partículas: The repeated impact fractures the ore particles through compressive force.
4. Formação de Polpa & Descarga: Crushed material is washed over a discharge screen with water; fine particles pass through as slurry for further concentration (por exemplo, via sluices or shaking tables), enquanto o material de tamanho grande é recirculado.

Escopo de aplicação & Limitações:
Ideal para: Processing freemilling alluvial or hard rock ores where coarse to medium grinding is sufficient for initial gold liberation. Suited for operations processing 10500 toneladas por dia.
Limitações: Not suitable for refractory ores requiring ultrafine grinding or complex chemical treatment. O desempenho é ideal com distribuição consistente do tamanho da ração.
