1. ABERTURA ACIONADA POR PAINPOINT

Are your gold processing operations constrained by inefficient primary size reduction? The initial crushing stage sets the tone for your entire recovery circuit. Os desafios comuns com equipamentos de britagem de minério de ouro abaixo do ideal incluem:
Alto custo operacional: Consumo excessivo de energia por tonelada de minério processado e frequentes, unplanned downtime for liner changes and repairs directly erode profit margins.
Gargalos de rendimento: Inconsistent feed size or capacity limitations in primary crushers create downstream inefficiencies in grinding and leaching circuits, limitando a produção geral da planta.
Desgaste prematuro & Manutenção: The abrasive nature of quartz and hard rock gold ore accelerates wear on crusher components, leading to high spare parts costs and lost production hours.
Libertação Ineficiente: Poorly sized crush product can hinder optimal gold liberation, potentially reducing overall recovery rates in subsequent stages.

Is your current primary crusher a source of variable cost and operational uncertainty? The solution lies in selecting robust, purposeengineered gold ore crushing equipment designed for high availability and lower costperton.

2. VISÃO GERAL DO PRODUTO

This product line focuses on Primary Jaw Crushers and Gyratory Crushers engineered specifically for hard rock gold ore processing. These machines are built for the first stage of size reduction, aceitando runofmine (ROM) alimentar diretamente da mina.

Fluxo de Trabalho Operacional:
1. Minério de ouro ROM (tamanho de pedaço de até 1,5 m) is fed into the crusher's receiving hopper.
2. A reciprocating jaw or gyrating mantle exerts immense compressive force against a stationary surface, quebrando o minério por pressão.
3. The crushed product discharges through an adjustable gap (configuração lateral fechada), determining the final topsize output for the SAG or ball mill feed conveyor.
4. Metal detectors and tramp release systems protect the internal mechanism from uncrushable material.

Escopo de aplicação: Ideal for medium to largescale gold mining operations processing hard rock ores (por exemplo, veios de quartzo, minérios contendo sulfureto). Suitable for both stationary plant installations and modular/trackmounted setups.

Limitações: Não projetado para molhado, minérios pegajosos sem escalpelamento prévio; requires a consistent feed system for optimal performance. Fine grinding is handled by downstream milling equipment.
