Titular: HighCapacity Alluvial Gold Recovery: The ODM 500 TPH Washing Plant for IndustrialScale Operations

Subtítulo: Engineered for continuous throughput, tiempo de inactividad mínimo, and maximum gold liberation in highclay, highgravel deposits.

Is Your Current Gold Recovery System Costing You 1520% of Your Yield?

You are managing a highvolume alluvial operation. You face the daily challenge of processing material with high clay content that clogs screens and reduces trommel efficiency. You see your recovery rates drop when dealing with cemented gravels, and you calculate the cost of unscheduled downtime for cleaning—often exceeding $2,500 por hora en pérdida de producción y mano de obra.

You need a system that can handle 500 toneladas por hora of runofmine feed without constant operator intervention. You require a plant that liberates gold at the first stage of washing, not after the material has passed through multiple, inefficient stages. El caso es: can your current washing plant maintain 95%+ availability on a 500 TPH feed with 30% contenido de arcilla?

The ODM 500 TPH Gold Mining Washing Plant is designed to answer that question with a specific engineering focus on highenergy scrubbing and efficient screening.

Descripción general del producto: The ODM 500 TPH Washing Plant

Este es un mobile or semimobile, modular washing and screening plant rated for a nominal feed capacity of 500 toneladas métricas por hora. It is a primary recovery solution for alluvial gold, depósitos de placer, and eluvial material.

Flujo de trabajo operativo:
1. Alimentar & Oso pardo: Runofmine material is fed via excavator or loader into a heavyduty vibrating grizzly feeder. Demasiado grande (+150milímetros) is scalped and rejected.
2. HighEnergy Scrubbing: The 150mm material enters a dualdrive, fregadora rotativa de servicio pesado. High water pressure and internal lifters create a turbulent slurry, breaking down clay balls and dispersing conglomerates.
3. Apresto & Cribado: The slurry passes through a multideck vibrating screen system (typically 20mm and 6mm apertures). This separates the +6mm gravel (desperdiciar) from the 6mm fines (concentrarse).
4. Concentración: The 6mm slurry is directed to a downstream recovery circuit (p.ej., plantillas, espirales, o concentradores centrífugos) which is integrated into the plant's design.

Ámbito de aplicación:

• Primario: Alluvial gold, eluvial gold, and weathered hardrock deposits.
• Secundario: Diamond recovery, tin/tantalum processing, and aggregate washing.
• Limitaciones: Not designed for dry processing or hardrock crushing. Requiere un suministro constante de agua. (aprox. 8001200 m³/hora).
