Fabricant certifié d'équipement d'extraction d'or

1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Commercial gold recovery operations face three persistent challenges: declining ore grades that reduce yield per ton processed, excessive fines loss in gravity circuits (souvent 1525% d'or récupérable), and unplanned downtime from equipment wear in abrasive slurry environments. Pour une transformation végétale 200 dpt, un 2% recovery loss at $2,000/oz represents over $250,000 in annual revenue forfeited. Does your current recovery circuit handle variable feed densities without requiring manual retuning? Are you replacing pump impellers or screen media every 90 days due to accelerated wear? These operational costs erode margins that certified gold mining equipment is designed to protect.

2. APERÇU DU PRODUIT

This certified gold mining equipment is a modular centrifugal concentrator system designed for primary recovery and scavenger applications in alluvial and hardrock gold processing plants.

Flux de travail opérationnel:
1. Préparation des aliments: Boue (2540% solides en poids) enters via a distribution box, sized to 6mm after primary crushing and screening.
2. Centrifugal Stratification: The rotating bowl generates up to 200 Forces G, stratifying material by specific gravity. Heavy gold particles migrate to the riffle bed.
3. Fluidization Water Injection: Eau à haute pression (46 bar) is injected through the bowl base to fluidize the bed, preventing compaction and allowing finer gold particles to settle.
4. Décharge de concentré: After a timed cycle (typiquement 24 heures), the bowl slows, and a concentrate valve opens to flush the highgrade fraction (typiquement 0.52% de masse alimentaire).
5. Enlèvement des résidus: Lighter gangue material overflows the bowl lip and is directed to the tailings launder.

Champ d'application: Suitable for placer mining, hardrock mill circuits, and tailings retreatment. Limites: Not designed for feed material exceeding 20% teneur en argile sans préconditionnement; requires consistent feed rate within ±15% of rated capacity.

8. FAQ

Q: Can this certified gold mining equipment handle feed material with high clay content?
UN: The standard unit operates effectively with up to 8% argile. For feed exceeding this, we recommend a preconditioning scrubber or adding a dispersant dosing system. Field data shows recovery drops by 2% per additional 3% clay without pretreatment.

Q: What is the expected lifespan of the tungsten carbide bowl lining?
UN: Dans des conditions normales de fonctionnement (feed with 25% quartz), the lining lasts 2,5003,000 heures. In highly abrasive feeds (10%+ quartz), attendre 1,8002,200 heures. Ultrasonic wear monitoring alerts you before failure.

Q: How does this compare to a Knelson or Falcon concentrator in terms of recovery?
UN: Independent testing at a 150 tpd mill showed our CGC2000 achieved 82% récupération pour 75 micron gold versus 78% for a comparable Knelson CD20. The primary advantage is 33% lower power consumption and 55% lower concentrate mass pull, réduire la charge en aval.

Q: Quel est le délai de livraison?
UN: Standard base units ship within 810 semaines à compter de la commande. Integrated packages require 1214 semaines. Turnkey systems are 1618 weeks due to conveyor and pump procurement.

Q: Do you offer onsite commissioning support?
UN: Oui. Turnkey packages include 2 semaines de mise en service. For base units, nous proposons un $12,000 commissioning package (1 semaine sur place) or remote support via video call at no charge.

Q: What voltage options are available for international operations?
UN: Standard is 480V/60Hz. We offer 415V/50Hz, 380V/50 Hz, and 600V/60Hz configurations. Transformers are available as an optional addon.

Q: Cet équipement peut-il être intégré dans un système de contrôle d'usine automatisé existant?
