1. ABERTURA ACIONADA POR PAINPOINT

Você está enfrentando gargalos persistentes no seu circuito de recuperação de ouro?? A britagem primária e a moagem ineficientes impactam diretamente o rendimento, taxas de recuperação, e custos operacionais. Common challenges with conventional comminution include:

Alto tempo de inatividade operacional: Frequent liner changes and unplanned maintenance on primary crushers halt your entire processing line, custando milhares por hora em perda de produção.
Inconsistent Feed Size for Milling: Poorly calibrated crushing leads to oversize material entering ball mills, reducing grinding efficiency and increasing power consumption per ton.
Consumo excessivo de energia: Inefficient size reduction technology can make comminution the single largest energy cost in your plant, corroendo as margens de lucro.
Altos custos com peças de desgaste: Agressivo, unoptimized crushing mechanisms result in premature wear of mortars, morre, e sapatos, leading to high recurring spare parts expenses.
Limited Flexibility for Variable Ore Hardness: Fixedspeed systems struggle with fluctuations in feed material, causing either underprocessing or equipment overload.

Sua operação está buscando uma solução robusta, proven solution to create a consistent, optimal feed for your gravity separation or leaching circuits while controlling capital and operational expenditure?

2. VISÃO GERAL DO PRODUTO

The modern heavyduty stamp mill is a purposebuilt primary crushing system designed for the reliable reduction of goldbearing quartz ore and hard rock feed material. It serves as a critical first stage in mineral liberation, preparing ore for secondary milling or direct gravity concentration.

Fluxo de Trabalho Operacional:
1. Introdução ao feed: Runofmine (ROM) ore is fed into a sealed hopper, regulating flow onto the stamp shoe.
2. Cyclic Percussive Crushing: Selos pesados ​​levantados mecanicamente (camshaft or hydraulic) drop onto the ore bed contained within a hardened mortar box.
3. Classificação de tamanho & Descarga: O material triturado passa por uma tela perfurada na base da caixa de argamassa. The screen aperture defines the maximum product size.
4. Pulp Handling (Opcional): Water can be introduced to create a slurry discharge for direct transport to subsequent wet processing stages.

Escopo de aplicação & Limitações:
Ideal para: Primary crushing of quartz veins, hard rock gold ores, and sulphidebearing materials. Adequado para operações de média escala (50500 TPD), modular plant designs, and regions with limited grid power availability.
Limitações: Não projetado para moagem fina; product size is typically 10mm to 20mm. Less effective for clayrich or highly abrasive ores without modification. Requires firm foundation due to dynamic loads.
