Reverse Helix Trommel Secondary
Designed to maximize fine gold recovery, this secondary system automates the tedious panning process.
The Extraction Process
-
Initial Wash: Material is added to the hopper where it receives an initial wash.
-
The Reverse Helix: Washed material flows into the 33-inch long, 7-inch wide barrel containing a 45-foot Reverse Helix Screw. This design provides maximum processing time to capture all gold.
-
Continuous Slurry: Inside the barrel, a full-length spray bar continuously washes the material, keeping it in a slurry.
-
Separation: Lighter material washes out the back into a waste bucket. Heavier, valuable material stays caught in the grooves of the reverse helix screw and is forced to the front.
-
Spiral Wheel Finishing: Heavy material drops from the trommel mouth directly into a standard 12″ Desert Fox Spiral wheel.
-
Final Polish: The spiral wheel slowly and meticulously washes away black sand and unwanted materials, moving the pure gold up the riffles and safely into the collection cup.
Optional Mill Table
