1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you facing escalating operational costs and unpredictable output in your largescale gold mining operation? For commercial buyers and plant managers overseeing hightonnage projects, les défis d'un 500 TPH washing plant are significant:
High Downtime from Blockages: Claybound or sticky material can halt your entire processing line, costing thousands per hour in lost production and labor for manual clearing.
Taux de récupération incohérents: Inefficient scrubbing and screening lead to goldbearing fines bypassing recovery circuits, directly eroding your project's profitability.
Eau excessive & Consommation d'énergie: Outdated washing technology consumes unsustainable volumes of water and high horsepower, creating both environmental compliance pressures and crippling utility costs.
Usure rapide des composants: Abrasive feed material degrades liners, écrans, and pump systems prematurely, ce qui entraîne de fréquents, unplanned maintenance shutdowns and high parts inventory costs.

Is your current setup delivering the consistent 500tonperhour throughput your reserve model requires? Are you achieving maximum gold liberation while controlling your most variable operating expenses?

2. APERÇU DU PRODUIT

Le moderne 500 L'usine de lavage de l'or TPH est une installation modulaire, heavyduty processing system designed for alluvial, au bord de la survie, or weathered hard rock deposits. Its primary function is to disaggregate, scrub, and classify ore to prepare liberated gold for downstream concentration (par ex., écluses, centrifugeuses).

Flux de travail opérationnel:
1. Alimentation principale & Scalping: Runofmine (ROM) material is uniformly fed via apron feeder to a robust scalping screen, removing oversized waste (+75mm) before the scrubber.
2. Gommage intensif & Libération: The core rotary scrubber or trommel uses internal lifters and highpressure water sprays to break down clay matrices and cementation, thoroughly liberating gold particles.
3. Classification précise des particules: Discharged material is screened into multiple fractions (par ex., +10mm gravel waste, 10mm+2mm sand, 2mm slimes). This critical step ensures optimal feed sizing for downstream recovery units.
4. Gestion des résidus & Gestion de l'eau: Efficient slurry pumps and cyclones manage fine tailings streams. Integrated water recovery systems recirculate up to 90% d'eau de procédé.

Champ d'application & Limites:
Portée: Ideal for surface mining operations with claybound auriferous gravels, saprolitic (patiné) dépôts, and alluvial placer projects requiring highvolume throughput.
Limites: Not suitable for competent hard rock without prior crushing. Performance is highly dependent on accurate feed characterization regarding clay content and plasticity.
