1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you scaling up alluvial or eluvial gold operations but finding that your recovery plant is the bottleneck? Operational challenges with highcapacity washing plants directly impact your bottom line. Les problèmes courants incluent:
Gestion incohérente des aliments: Fluctuating feed rates and claybound materials can choke standard scrubbers, leading to daily hours of unplanned downtime for manual clearing.
Inefficient Fines Loss: Inadequate screening and sluicing design in highvolume flows result in significant fine gold loss, with industry estimates suggesting unrecoverable losses can exceed 515% in poorly configured systems.
Eau excessive & Consommation d'énergie: Outdated plant designs lack recirculation optimization and efficient drive systems, inflating operational costs by hundreds of thousands annually.
High Maintenance Demands: Poorly fabricated components and abrasive wear in critical areas lead to frequent component replacement, halting your 500 Tph operation for costly repairs.

Is your current setup causing unpredictable throughput, unacceptable recovery rates, and uncontrollable operating expenses? The solution requires a plant engineered not just for scale, but for reliable, efficace, and profitable performance.

2. APERÇU DU PRODUIT

Le 500 L'usine de lavage minière Tph Gold est une installation complète, modular processing system designed for the continuous recovery of gold from alluvial, placer, et dépôts éluviaux. Il intègre l'alimentation, lavage, lavage, dépistage, and concentration into a single, flux coordonné.

Flux de travail opérationnel:
1. Alimentation & Présélection: Runofmine material is uniformly fed via a heavyduty apron feeder onto a primary scalping screen to remove oversize rocks (>75mm).
2. Usure & Libération: The sub75mm material enters a robust rotary scrubber or trommel, where intense washing and attrition break down clay matrices and liberate gold particles.
3. Classification & Concentration: Liberated material reports to vibrating screens for precise size classification. The goldbearing fraction (typically 10mm) is routed to a series of highcapacity sluices or centrifugal concentrators for primary recovery.
4. Gestion des résidus & Recyclage de l'eau: Processed tailings are conveyed to a designated area, while process water is channeled through settling ponds or clarifiers for recirculation.

Champ d'application & Limites:
Portée: Idéal pour les opérations minières alluviales/placeriennes à grande échelle, dépôts fluviaux, and weathered eluvial zones with high clay content requiring attrition.
Limites: Ne convient pas au hard rock (filon) ore requiring crushing and milling. Optimal performance assumes adequate feed preparation (removal of extreme boulders) and a sustained water supply within specified parameters.
