Haute qualité 500 Tph Gold Mining Washing Plant Quality Control

Your Production Targets Are Only as Reliable as Your Washing Plant

Chaque directeur d'usine connaît les calculs: un 500 tph gold washing plant operating at 85% availability delivers 4,250 tons per shift. Drop that to 70% à cause de l'aveuglement de l'écran, pump cavitation, or slurry channeling, and you lose 750 tons daily—at $35 per ton processing cost, c'est $2,250$3,750 in lost margin every day. Pour les entrepreneurs en ingénierie, the risk is compounded: a plant that fails performance guarantees during commissioning triggers liquidated damages averaging 0.51.5% of contract value per week of delay.

Are your current washing systems delivering consistent recovery above 92% across variable feed grades? Can your plant handle claybound ores without requiring daily manual cleaning? Does your quality control protocol include realtime density monitoring and particle size distribution tracking? Sinon, you're leaving recoverable gold in the tailings and paying for unplanned downtime.

Présentation du produit: Le 500 Usine de lavage d'extraction d'or Tph

This is a fully integrated, modular gold washing system designed for alluvial and eluvial deposits with throughput capacities of 500 tonnes métriques par heure. The plant combines scrubbing, dépistage, and gravity concentration in a closedloop water management system.

Flux de travail opérationnel:

1. Préparation des aliments: Matériel tout-venant (jusqu'à 600 mm) enters the grizzly feeder; surdimensionné (+150mm) is rejected to a stacking conveyor
2. Gommage intensif: Dualshaft paddle scrubber with adjustable retention time (24 minutes) breaks down clay agglomerates at 6575% solids density
3. Dépistage primaire: 2deck vibrating screen with 10mm and 3mm apertures; surdimensionné (+10mm) reports to waste, intermediate (310mm) to secondary processing
4. Récupération d'or fin: Hydrocyclone cluster (6x 250mm) feeding a 30tph jigging circuit and two 5tph centrifugal concentrators in parallel
5. Gestion des résidus: Thickener underflow at 5560% solids for dry stacking; clarified water returns to process at 9095% taux de récupération

Champ d'application: Alluvial gold deposits, weathered saprolite, river terrace gravels, and beach sands with clay content up to 40%. Not suitable for hardrock primary ores requiring crushing circuits.

FAQ

Q: Can this plant handle feed material with more than 40% teneur en argile?
UN: Oui, but with modifications. For clay content above 40%, we recommend upgrading to a 3paddle scrubber configuration and increasing retention time to 45 minutes. Field data from operations in Indonesia (55% argile) shows 91% recovery with this configuration.

Q: What is the expected lifespan of wear components?
UN: Basé sur 8,000 heures de fonctionnement par an: scrubber paddles (12% fer chromé) last 3,0004,000 heures; polyurethane screen panels last 6,0008,000 heures; cyclone liners (27% fer chromé) last 2,5003,500 heures. Actual lifespan depends on feed abrasivity and operating parameters.

Q: Comment la plante se comporte-t-elle dans les climats froids?
UN: The plant is designed for ambient temperatures down to 5°C. For subzero operations, we offer a coldclimate package including heated scrubber jackets, insulated piping, and glycolbased antifreeze injection. Minimum operating temperature with this package is 15°C.

Q: What is the typical commissioning timeline?
UN: For a standard installation with prepared site and utilities, commissioning takes 710 jours. This includes mechanical completion, tests électriques, dry run (2 jours), wet commissioning with water (2 jours), and ore commissioning (36 jours). Remote locations with limited craneage may extend this to 14 jours.

Q: Can the plant be integrated with existing crushing circuits?
UN: Oui. The grizzly feeder accepts feed from conveyors, dump hoppers, or crusher discharge. We provide interface drawings and can supply transition conveyors. For plants requiring primary crushing, we recommend a jaw crusher set at 150mm CSS upstream of the grizzly.

Q: What quality control documentation is provided?
UN: Each plant ships with: material test certificates for all structural steel and wear parts, weld inspection reports (UT/MPI for critical welds), pump and motor performance curves, screen vibration analysis report, and a factory acceptance test (GRAISSE) certificate. SCADA systems include 14day historical data logging for process verification.

Q: Quelle est la couverture de la garantie?
UN: La garantie standard est 12 mois à compter de la mise en service ou 18 mois à compter de l'expédition, selon la première éventualité. Covers manufacturing defects in materials and workmanship. Garantie prolongée (24 mois) est disponible à 4.5% de la valeur de l'équipement. Excludes wear parts and consumables.
