1. ABERTURA ACIONADA POR PAINPOINT

Você está gerenciando operações de recuperação de ouro sobrecarregadas por taxas de transferência inconsistentes?, custos excessivos de manutenção, and inefficient liberation of values from complex ores? Legacy crushing and grinding circuits often struggle with hard rock material, leading to premature wear part failure, tempo de inatividade não planejado para trocas de revestimento, and suboptimal particle size distribution for downstream cyanidation or gravity concentration. This directly impacts your bottom line through lost production hours, high consumable costs, and potential gold losses in coarse tailings. How can you increase milling capacity while controlling operational expenditure? Is your current process reliably delivering the optimal grind size for maximum gold recovery? A solução está na engenharia de propósito, robust technology designed for this specific task.

2. VISÃO GERAL DO PRODUTO

Esta linha de produtos compreende serviços pesados Stamp Mills engineered for the primary crushing and coarse grinding of goldbearing ores. As an OEM factory, we specialize in the direct sourcing and manufacturing of these mills for commercialscale mining and processing operations.

Fluxo de Trabalho Operacional:
1. Introdução ao feed: Runofmine or primarycrushed ore is fed into a mortar box.
2. Percussive Grinding: Selos levantados mecanicamente (varas pesadas com marretas) são descartados sequencialmente no minério.
3. Redução do tamanho das partículas: The repeated impact fractures the rock material.
4. Descarga de lama: A continuous wash of water carries the ground slurry through a perforated screen plate for discharge.
5. Concentração Gravitacional: The slurry is often directed directly over amalgamation plates or to downstream concentrators like shaking tables.

Escopo de aplicação & Limitações:
Escopo: Ideal for freemilling gold ores, particularly in remote locations or smallerscale operations where simplicity, confiabilidade, and the ability to process coarse feed are paramount. Effective as a primary grinder ahead of finer milling circuits or for direct amalgamation.
Limitações: Not suitable for ultrafine grinding requirements (por exemplo, abaixo 150 malha). Efficiency decreases with very wet, clayrich ores that can cause packing. Requires a consistent feed size to maintain optimal performance.
