1. ABERTURA ACIONADA POR PAINPOINT

Você está gerenciando operações de recuperação de ouro sobrecarregadas por taxas de transferência inconsistentes?, tempo de inatividade excessivo para manutenção, e custos operacionais imprevisíveis? Key challenges in primary ore crushing and liberation often include:

Alto tempo de inatividade operacional: Frequent liner changes and mechanical failures in crushing circuits halt your entire processing line, custando milhares por hora em perda de produção.
Liberação Ineficiente de Ouro: Inconsistent particle size from primary crushers leads to poor contact in subsequent leaching or gravity circuits, directly reducing overall recovery rates.
Consumo excessivo de energia: Older crushing technologies consume disproportionate power per ton of ore processed, corroendo as margens de lucro.
Altos custos de mão de obra de manutenção: Complexo, laborintensive maintenance routines for legacy stamp mills or jaw crushers increase your total cost of ownership and safety exposure.
Limitações de escalabilidade: Inflexible equipment that cannot adapt to varying ore hardness or feed grades creates bottlenecks in expanding operations.

Sua operação está buscando uma solução robusta, highavailability solution for primary gold ore reduction that delivers consistent sizing, reduces lifecycle costs, and protects your recovery circuit’s efficiency?

2. VISÃO GERAL DO PRODUTO

The modern heavyduty stamp mill is a mechanized percussion crushing system engineered for the primary liberation of gold from quartz and hard rock ore. It is designed as a reliable, highimpact workhorse for mediumtohigh volume operations where consistent sub10mm output is critical for optimal downstream cyanidation or gravity recovery.

Fluxo de Trabalho Operacional:
1. Introdução ao feed: Runofmine (ROM) o minério é alimentado em uma robusta caixa de argamassa de aço.
2. Percussão Mecânica: Powered camshafts lift and release a series of weighted stamps (5002000kg cada), delivering controlled, highimpact blows onto the ore bed.
3. Redução Progressiva: Ore is crushed through repeated impact against hardened die plates within the mortar box.
4. Descarga de lama: Finely crushed material exits through a discharge screen at the mortar box perimeter, mixed with water to form a slurry ready for secondary processing.

Escopo de aplicação & Limitações:
Ideal para: Minérios de ouro de rocha dura (veios de quartzo), plantas piloto, operations prioritizing mechanical simplicity and high uptime over ultrafine grinding.
Limitações: Não é adequado para macio, minérios ricos em argila que causam empacotamento; requires consistent feed size (tipicamente <100milímetros); operates most efficiently within defined moisture content parameters.
