Atacado 500 TPH Gold Mining Washing Plant Producer

The Hidden Costs of Underpowered Gold Recovery Systems

Your current washing plant is processing 500 tons per hour—on paper. Na realidade, downtime from clogged screens, inadequate scrubbing, and inefficient gold recovery is costing your operation $12,000–$18,000 per day in lost production. Field audits across West African and South American alluvial sites show that plants operating below 85% availability lose 30–40% of fine gold (<100 malha) para rejeitos.

Are you still relying on multiple smaller units that require constant operator intervention? Can your existing setup handle highclay feed material without weekly screen replacements? Does your current supplier provide consistent quality across bulk orders for multiple site expansions?

Visão geral do produto: O 500 TPH Rotary Trommel & Sluice System

Esse wholesale 500 tph gold mining washing plant é modular, dieselelectric driven system designed for continuous alluvial and eluvial gold recovery operations. The equipment integrates three core processes into a single production line:

Fluxo de Trabalho Operacional:
1. Funil de alimentação & Pardo – 50ton capacity hopper with vibrating grizzly feeder (100mm bar spacing) removes oversize material before washing
2. Rotary Trommel Scrubber – 2.4m diameter × 8.0m length drum with internal lifters and highpressure spray bars (12 bar) breaks down clay agglomerates
3. DoubleDeck Vibrating Screen – 6.0m × 2.4m screen with 6mm and 2mm mesh decks classifies material for downstream processing
4. Concentrator Circuit – 4 banks of 20channel sluice boxes with expanded metal riffles and rubber matting capture free gold
5. Descarga de Rejeitos – 30m conveyor system with water recycling (85% recovery rate via hydrocyclone)

Escopo de aplicação: Alluvial gold deposits, rocha dura resistida, river terrace gravels, and old tailings reprocessing
Limitações: Não é adequado para britagem primária de rocha dura; requires feed material with <15% superdimensionado (+100milímetros) content

Perguntas frequentes

P: Can this 500 tph plant handle feed material with 40% teor de argila?
UM: Sim. The 8meter trommel with 12bar spray pressure and counterrotational lifters is designed for clay content up to 45%. Field data from Ghana operations shows 98% disaggregation at 38% clay with 90second retention time.

P: What is the expected gold recovery rate for fine particles (100 malha)?
UM: With the standard sluice configuration, recovery averages 82–85% for 100 malha de ouro. Adding the optional centrifugal concentrator increases this to 90–93%. Recovery for +100 mesh gold consistently exceeds 97%.

P: How many containers are required for shipping, and what are the dimensions?
UM: The plant ships in 4 standard 40foot opentop containers. O volume total de envio é 2,400 cubic feet. Each module weighs between 14,000–20,000 kg. No special heavylift equipment is required for unloading.

P: What is the lead time for wholesale orders of 5+ unidades?
UM: Standard lead time for single units is 12–14 weeks. For wholesale orders of 5+ unidades, production is staggered at 3 units per month, with first shipment at 16 weeks and full delivery within 24 semanas. Volume orders receive priority engineering support.

P: Can the plant be modified for different site conditions after purchase?
UM: Sim. The modular design allows screen mesh changes (2–12 mm), trommel speed adjustment via VFD (8–16 RPM), and sluice angle adjustment (5–12°). Retrofit kits are available for highaltitude sites (up to 4,000m) and cold climates (down to 20°C).

P: What is the warranty coverage, and what is excluded?
UM: Coberturas de garantia padrão 24 meses ou 8,000 operating hours for structural components, 12 months for wear parts (telas de bateria, sluice mats, impulsores de bomba). Exclusões: danos por operação inadequada, unauthorized modifications, normal wear on consumables, e eventos de força maior.

P: How does the water recycling system affect overall water consumption?
UM: The integrated hydrocyclone and settling tank system recovers 85% de água de processo. Net water consumption is 0.5–0.7 m³ per ton processed, compared to 1.0–1.5 m³ for plants without recycling. This reduces makeup water requirements by 60,000–80,000 liters per hour at full capacity.
