1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Vos opérations de traitement de l’or sont-elles limitées par une réduction inefficace de la taille primaire ?? L’étape initiale de concassage donne le ton à l’ensemble de votre circuit de valorisation. Les défis courants liés aux équipements de concassage de minerai d'or sous-optimaux comprennent:
Coût opérationnel élevé: Consommation d'énergie excessive par tonne de minerai traité et fréquente, unplanned downtime for liner changes and repairs directly erode profit margins.
Goulots d’étranglement du débit: Inconsistent feed size or capacity limitations in primary crushers create downstream inefficiencies in grinding and leaching circuits, capping overall plant output.
Usure prématurée & Entretien: 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.
Libération inefficace: 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. APERÇU DU PRODUIT

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, accepting runofmine (ROM) nourrir directement de la mine.

Flux de travail opérationnel:
1. Minerai d'or ROM (jusqu'à 1,5 m de taille de morceau) is fed into the crusher's receiving hopper.
2. A reciprocating jaw or gyrating mantle exerts immense compressive force against a stationary surface, casser le minerai par pression.
3. The crushed product discharges through an adjustable gap (réglage côté fermé), 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.

Champ d'application: Ideal for medium to largescale gold mining operations processing hard rock ores (par ex., veines de quartz, minerais sulfurés). Convient aux installations d'usine stationnaires et aux configurations modulaires/montées sur rail.

Limites: Non conçu pour être mouillé, minerais collants sans scalpage préalable; requires a consistent feed system for optimal performance. Fine grinding is handled by downstream milling equipment.
