5 To 10 Tons Per Hour Small Gold Trommel

Zhengzhou Sinolion Machinery Co., Ltd. is one of the most credible manufacturers and suppliers of 5 to 10 tons per hour small gold trommel in China. Please feel free to buy high quality 5 to 10 tons per hour small gold trommel for sale here from our factory. Good service and reasonable price are available.

 

 

Selecting equipment for small-scale placer mining requires balancing processing throughput, equipment mobility, and total capital expenditure. The 5 to 10 tons per hour (TPH) small gold trommel is an entry-level, heavy-duty mobile processing unit designed specifically for alluvial deposits, river sediments, and clay-heavy sand gravels.

 

Rather than functioning as a standalone gold trap, this portable rotary screen serves as the primary washing and classification hub within a compact gravity separation circuit. By breaking up consolidated dirt and separating barren rock on-site, operators can maximize fine gold recovery through downstream concentration units.

Chassis Type	Towable Axle / Skid-Mounted Mobile Frame	Rapid transport across unpaved mining tracks
Structural Steel	Heavy-Duty Q235 Carbon Steel	High impact toughness, easy field welding/repair
Feed Compatibility	Alluvial sand, river gravel, clay dirt	Processes mixed matrixes directly at the pit
Assembly Time	~0.5 Day (4 Hours)	Minimal site prep; no permanent concrete pad required
Downstream Pairing	Sluice, Centrifugal Unit, Jig, Table	Modular expansion based on deposit characteristics

 

 

 

Heavy-Duty Q235 Steel Fabrication

The hopper, main supporting frame, and drum housing are constructed using Q235 carbon steel. Q235 steel provides an optimal balance of yield strength, impact resistance, and cost efficiency. In tough field conditions, Q235 allows the machine frame to absorb mechanical stress during high-volume feeding while remaining easy to repair or weld using standard site equipment.

 

Towable Mobility & Half-Day Deployment

Time lost during equipment relocation directly impacts daily yield. Equipped with a heavy-duty towable chassis, this mobile trommel can be pulled by a light tractor or 4x4 vehicle directly to the working face.

 

• Zero Concrete Foundation Needed: The unit stabilizes on leveled, compacted soil using mechanical jacks.

 

• Rapid Commissioning: Most field crews complete mechanical setup, drum leveling, and water pump pipe connections within half a day.

 

• Reduced Transport Distance: As the mining pit advances, the trommel moves alongside the excavator, keeping haul truck cycles short.

 

 

 

Complete 4-Stage Placer Gold Processing Workflow

To capture fine particle gold alongside coarse flakes, this mobile wash plant operates as Stage 1 and Stage 2 in a full 4-stage gravity recovery system.

 

Stage 1: Washing & Scrubbing (Handling Clay vs. Sand)

The primary objective of Stage 1 is breaking the bond between clay and gold.

 

• Standard Alluvial Ore (Low Clay): High-pressure internal spray nozzles inside the rotating trommel drum blast loose gravels clean, washing gold particles directly into suspension.

 

• Sticky Clay & River Dirt (Heavy Mud): When raw ore contains plastic clay balls, material requires intensive scrubbing. A trommel scrubber section (or internal drum lifters) tumbles the wet mass until mud lumps dissolve completely into slurry before reaching the screen mesh.

 

Stage 2: Particle Classification & Oversize Discharge

Classification takes place as material travels through the rotating screen drum:

 

• Oversize Rocks (>6mm or >10mm): Fully scrubbed cobbles and rocks roll out the lower end of the drum, forming a clean tailings pile free of gold coating.

 

• Undersize Slurry (<6mm or <10mm): Fine sand, heavy minerals, and liberated gold drop through the perforated screen into the bottom hopper, flowing directly toward gravity concentration.

 

Stage 3: Gravity Separation Circuit Options

Because gold possesses a specific gravity of ~19.3 compared to quartz sand (~2.65), gravity separation equipment captures free gold from the undersize slurry. Depending on mine budget and gold particle size distribution, operators can utilize one or a combination of four core machines:

 

• Sluice Box with Gold Carpet: Cost-effective sluicing using Miners Moss or riffled matting to trap medium-to-coarse gold flakes.

 

• Gold Centrifugal Concentrator: Uses high-G centrifugal force to trap fine and ultra-fine gold dust that would otherwise escape standard sluice mats.

 

• Jig Separator: Handles high-volume feed variations and efficiently catches coarse gold nuggets.

 

• Shaking Table: Provides precise final upgrading of heavy sand concentrates into high-grade gold concentrates.

 

• Operational Insight: Running a single sluice box keeps start-up costs minimal. However, combining a centrifugal concentrator, sluice box, and shaking table in sequence delivers the maximum overall recovery rate across all grain sizes.

 

Stage 4: Gold Refining & Smelting

The high-grade concentrate collected from Stage 3 undergoes final processing:

• Amalgamation / Chemical-Free Separation: Isolates heavy gold grains from residual iron sand.

 

• Mercury Distiller Retort: Safely recovers mercury reagents when amalgamation is used, containing toxic vapors.

 

• Gold Smelting Furnace: Melts clean gold concentrate with fluxes (borax/silica) to pour pure market-ready gold bullion bars.

 

 

Field Operating Best Practices for Mine Sites

To maintain an efficient 5 to 10 TPH processing rate without losing fine gold into tailings, field operators should observe four practical guidelines:

 

• Balance Water Flow and Pressure: Maintain consistent water volume inside the drum. Too little water leaves clay unwashed, carrying gold out with waste rocks. Excess water velocity washes fine gold straight over sluice riffles.

 

• Maintain Uniform Bucket Feeding: Avoid dumping massive excavator loads into the hopper at once. Feeding the hopper at a steady rate ensures optimal washing residence time inside the drum.

 

• Inspect Screen Mesh for Blinding: Periodically check screen panels for wedged stones or wear. The accessible Q235 frame structure allows for fast screen panel replacements or mesh clearing.

 

• Utilize Remote Technical Support: Complete user guides cover installation and routine maintenance. When unexpected soil conditions occur, remote technical support helps operators adjust water spray positioning and drum slope angles quickly.

 

 

Conclusion

The 5 to 10 tons per hour small gold trommel offers small-scale mining enterprises a practical, highly mobile washing solution. Engineered with durable Q235 steel, easily towable across rugged terrain, and operational within half a day, it eliminates the bottleneck of washing sticky river dirt and screening waste rock. When integrated with sluices, centrifugal concentrators, and shaking tables, this mobile unit provides a clear, reliable pathway from raw river bank deposit to refined gold bar.
