1. ABERTURA ACIONADA POR PAINPOINT

Are you managing a gold processing operation where throughput and recovery rates are compromised by inconsistent or inefficient primary crushing and grinding? The performance of your initial comminution stage sets the tone for your entire recovery circuit. Common challenges with conventional stamp mill operations include:

Tempo de inatividade excessivo para manutenção: Frequent breakdowns of cast components and wear parts lead to unplanned stoppages, custando centenas de dólares por hora em perda de produção.
Distribuição inconsistente de tamanho de partícula: Poorly controlled drop weight and alignment result in unevenly crushed ore, creating bottlenecks in downstream processes like cyanidation or gravity separation and reducing overall gold recovery.
Altos custos operacionais de mão de obra: Monitoramento manual, mechanical adjustments, and feeding inconsistencies demand constant operator attention, increasing labor overhead and the risk of human error.
Significant Energy Inefficiency: Older designs waste substantial power on friction, vibração, and nonproductive movement, directly impacting your cost per ton processed.

Sua operação está buscando uma solução robusta, highcapacity primary grinding solution that delivers consistent 20 mesh output with maximum uptime and measurable energy savings?

2. VISÃO GERAL DO PRODUTO

The Modern Luxury Stamp Mill is a precisionengineered, heavyduty gravitydriven crushing and grinding assembly plant designed for the primary liberation of gold from quartz ore. It serves as the cornerstone of a gravity concentration or leaching plant, transformando runofmine (ROM) ore into a finely milled slurry suitable for further processing.

Fluxo de Trabalho Operacional:
1. Alimentação controlada: ROM ore is uniformly fed via a vibratory grizzly feeder to remove oversize waste rock.
2. Precision Crushing: Ore enters the mortar box where mechanized, weighted stamps (cams or lifters) are raised and dropped in a controlled sequence.
3. Continuous Grinding: The repeated impact of the stamps pulverizes ore against a hardened die block within the mortar box.
4. Descarga de lama & Classificação: Crushed material is washed through a discharge screen with water, creating a slurry. Oversize particles are recirculated; fines proceed to concentration.

Escopo de aplicação & Limitações:
Escopo: Ideal for freemilling gold ores where gold is liberated at coarse to medium particle sizes. Highly effective in remote locations with reliable water supply but potentially limited grid power.
Limitações: Not suitable for refractory ores requiring ultrafine grinding (<100 malha) or complex sulfide mineralization. Requires a consistent feed size (tipicamente <2 polegadas) for optimal operation.
