Gold Wash Plant Trommel Gold Separation Equipment 5TPH-200TPH

Gold wash plant trommel

1.Product Introduction Gold Separation Equipment

The Gold Trommel Wash Plant is the industry standard for alluvial (placer) gold recovery, specifically designed to process gold-bearing gravels, sands, and ores with high clay content. Unlike flat vibrating screens, the trommel uses a rotating cylindrical drum to provide aggressive mechanical scrubbing. This tumbling action, combined with high-pressure water internal spray bars, breaks down "clay balls" and cemented gravels, liberating fine gold that would otherwise be lost in waste tailings. It serves as the primary "cleaning and sizing" station, feeding enriched material into secondary recovery systems like sluice boxes, jigs, or centrifugal concentrators.

2.Application Gold Separation Equipment

• Alluvial/Placer Gold Mining: The primary tool for riverbed, beach, and ancient channel deposits containing loose or cemented gold.

• Clay-Heavy Deposits: Specifically engineered for "sticky" ores where gold is trapped in mud or clay matrix.

• Sand & Gravel Grading: Simultaneously produces clean, graded construction aggregates as a byproduct of the gold recovery process.

• Gemstone Recovery: Effective for separating diamonds, sapphires, and other high-density minerals from raw earth.

3.Working Principle Gold Separation Equipment

• Rotary Scrubbing & Washing: Material enters the hopper and moves into the rotating drum. Internal lifter bars tumble the ore, while high-pressure water jets continuously wash the material, dissolving clay and stripping gold from larger rocks.

• Size Classification: The drum is composed of perforated screen plates (typically 12mm to 25mm apertures). Smaller gold-bearing fines fall through the screen into the recovery system, while large, barren rocks (oversize) are discharged out the end of the drum.

• Gravity Concentration: The "undersize" slurry flows over a series of recovery tools—most commonly Sluice Boxes lined with gold carpet, or Centrifugal Concentrators—where the heavy gold settles and the lighter sands are washed away.

• Mobile Flexibility: Most units are mounted on a heavy-duty wheeled chassis with integrated leveling jacks, allowing the plant to follow the mining face as it progresses.

4.Advantages Gold Separation Equipment

• Superior Clay Liberation: The "washing machine" effect of the rotating drum is far more effective at breaking up sticky clay than any vibrating or static screen.

• High Gold Recovery (90%+): By ensuring all material is thoroughly scrubbed before screening, it prevents "nugget robbery" where gold remains stuck to discarded rocks.

• Low Maintenance & High Durability: The simple rotating design has fewer high-wear moving parts than vibrating motors, leading to longer service intervals and lower operating costs in remote areas.

• High Throughput: Capable of processing massive volumes—from small 5 TPH units for prospecting to 300+ TPH industrial plants for large-scale operations.

• Anti-Clogging Design: The constant tumbling of material naturally clears the screen apertures, preventing "blinding" even when processing wet, muddy feedstock.
