1. ABERTURA ACIONADA POR PAINPOINT

Are you facing persistent bottlenecks in your primary crushing and grinding circuit? The consistent, highvolume processing of goldbearing ore is fundamental to profitability, yet traditional comminution methods often introduce significant operational friction. Os principais desafios incluem:

Tempo de inatividade excessivo para manutenção: Frequent liner changes and mechanical failures in complex grinding systems halt your entire processing line, custando milhares por hora em perda de produção.
Alto Consumo de Energia por Tonelada: Inefficient crushing and grinding directly inflate your most variable cost—energy—eroding margins, especially in remote sites with expensive power.
Distribuição inconsistente de tamanho de partícula: Poorly controlled discharge from primary crushing leads to inefficient cyanidation or gravity recovery downstream, resulting in lower overall gold recovery rates.
Altos custos com peças de desgaste & Complexidade: Systems with numerous moving parts and specialized components drive up ongoing spare part inventories and require highly skilled technicians for upkeep.
Limitações de escalabilidade: Modular or phased expansion can be prohibitively difficult with integrated, highcapacity milling systems.

Existe um robusto, simplified solution that delivers reliable throughput with lower operational complexity and a demonstrable return on investment for mediumtohigh tonnage operations?

2. VISÃO GERAL DO PRODUTO

O moderno Moinho de carimbos is a purposebuilt, heavyduty crushing apparatus designed for the reliable primary reduction of gold quartz ore. It operates on the proven principle of repetitive percussive crushing, delivering a consistent coarse to mediumfine feed ideal for secondary ball milling or direct cyanidation heap leach preparation.

Fluxo de Trabalho Operacional:
1. Alimentar: Runofmine (ROM) ore is fed into a sturdy mortar box via a regulated feed system.
2. Esmagamento: Selos pesados ​​levantados mecanicamente (pesos) are dropped onto the ore bed, fraturar o material através de impactos repetidos.
3. Classificação & Descarga: Crushed material passes through a perforated screen at the mortar box's base; oversize material remains for further crushing while correctly sized pulp discharges.
4. Slurry Transport: The discharged slurry is conveyed to the next stage in your beneficiation process.

Escopo de aplicação & Limitações:
Ideal para: Hard rock gold quartz veins, sulfide ores requiring preoxidation size reduction, and operations prioritizing mechanical simplicity and durability over ultrafine grinding.
Best Suited: For operations processing 50500 toneladas por dia, often as a primary crusher ahead of ball mills or in standalone setups for coarse gold recovery circuits.
Limitações: Not designed for producing ultrafine powder (<100 malha) as a final product; less energyefficient than some technologies for very soft ores; requires solid foundational support due to dynamic loads.
