How to Set Up an Automatic Gold Panning Machine (Spiral Wheel)
Spiral gold wheel setup comes down to four adjustments: a level base, the right wheel tilt, a water spray aimed just above the center hole, and a slow, steady feed of classified concentrates. Start with the manufacturer's recommended angle, run a test batch with known gold, then fine-tune wheel speed, angle and water until gold climbs the spirals into the cup while black sand washes off the bottom edge.
An automatic gold panning machine takes the most tedious part of prospecting, finishing concentrates, and turns it into a process you can run while doing other things. But a wheel that is set up poorly loses gold just as easily as a rushed hand pan. This guide covers how spiral wheels work, step-by-step setup, and how to troubleshoot recovery problems.
How a Spiral Gold Wheel Works
A spiral wheel is a tilted, rotating disc with spiral riffles molded into its face. The lower part of the wheel sits in a shallow pool of water. As the wheel turns, the riffles carry heavy material up and inward toward a hole in the center. A spray bar washes water down across the wheel's face, pushing lighter material back down and off the bottom edge. Gold, being the heaviest particle, stays in the riffles, travels to the center, and drops through the hole into a recovery cup.
Some wheels use a second set of riffles near the center to clean the concentrate further before it reaches the hole. The principle is the same density separation as a gold pan, applied continuously.
What You Need Before You Start
- The wheel and its tub or base. Most portable units recirculate water from their own tub with a small pump.
- A 12-volt power source. Camel Mining's wheels run on 12V DC. A deep-cycle battery or a suitable DC power supply works; check your manual for fuse and amperage requirements.
- Clean water. Enough to fill the tub to the level the manual specifies. The pump must stay submerged; running a pump dry can damage it.
- A wetting agent (surfactant). A small amount breaks surface tension so fine gold sinks instead of floating.
- Classified concentrates. Screened to a uniform size range. See our guide to classifying material and screen sizes.
- A test sample. A small amount of concentrate with known gold, or the practice material some manufacturers include.
Spiral Gold Wheel Setup: Step by Step
- Pick a level, stable surface. A workbench, tailgate or flat ground. If the base is tilted side to side, material drifts unevenly across the wheel.
- Fill the tub with water to the manual's level, and add the recommended amount of wetting agent.
- Screen the pump intake. Leaves, twigs and pebbles are the usual cause of pump clogs and blown fuses.
- Set the wheel tilt. Start at the manufacturer's recommended angle. Documentation for Camel Mining wheels describes roughly 45 degrees as a good starting point for most material. Steeper tilt makes gold work harder to climb and lets more sand wash off; shallower tilt carries more material to the center.
- Position the spray bar. Aim it so water flows across the wheel just above the center hole, often about an inch above it. Water should sheet across the riffles, not blast straight into them.
- Connect power and start the wheel. On variable-speed models, begin at a moderate speed.
- Feed slowly at the bottom of the wheel. Add concentrate a small scoop at a time into the water at the lower edge, letting the wheel pick it up. Overfeeding is the most common cause of gold loss.
- Watch the riffles. You want a thin line of black sand climbing the spirals. If the riffles fill solid with sand, slow the feed or steepen the tilt.
- Check the tailings. Pan a sample of what washed off the wheel. If you see gold, adjust before running more material.
Tuning: Speed, Angle and Water
The three main controls interact. Change one at a time, run a small batch, and check results.
| Symptom | Likely cause | Try this |
|---|---|---|
| Too much black sand reaching the cup | Tilt too shallow or water too weak | Steepen the wheel slightly or increase spray |
| Gold in the tailings | Overfeeding, tilt too steep, or too much water | Feed slower, reduce tilt, ease the spray |
| Riffles packed solid | Feed rate too high | Pause feeding and let the wheel clear |
| Fine gold floating | Surface tension | Add a little wetting agent |
| Material clumping on the wheel | Clay or unclassified feed | Break up clay and re-screen; use a small side jet if fitted |
| Pump stops or fuse blows | Clogged intake | Clean the intake and screen before replacing the fuse |
Why variable speed helps
Concentrates differ from site to site and even from bucket to bucket. Heavy black sand loads may need a slower wheel; lighter material can run faster. Variable-speed wheels let you match speed to the material instead of compensating only with tilt and water.
Choosing a Wheel Size
Camel Mining offers several sizes. Compare by volume of concentrates and how portable the setup must be.
| Model | Wheel | Speed | Typical use |
|---|---|---|---|
| Desert Fox Standard | Compact (12-inch class) | Fixed | Simplest setup for smaller batches |
| Desert Fox Variable Speed | Compact (12-inch class) | Variable | Changing concentrate types |
| Pro-Camel 18 | 18-inch | Per manufacturer specs | Balance of capacity and portability |
| Pro-Camel 24 | 24-inch, largest in lineup | Variable | High concentrate volumes from trommels or highbankers |

Running a Session: A Practical Routine
- Run your test sample first and confirm gold reaches the cup.
- Process the coarsest classified fraction, then the finer fractions separately.
- Empty the recovery cup into a pan between fractions so you can see results.
- Change the water when it becomes muddy, since silt slows separation.
- Pan-test the tailings at the end of the session.
- Rinse the wheel and pump with clean water before storage.
The recovery cup will rarely be pure gold. Expect a small amount of the heaviest black sand with it, which you can finish by hand. Our guide to gold cleanup from concentrates to clean gold covers that last step.
Realistic Expectations
Manufacturers describe their wheels as recovering very fine gold, with Camel Mining stating recovery down to roughly 100 mesh for its Pro-Camel models. Actual recovery depends on classification, feed rate, water flow, material composition and operator setup. No wheel guarantees a recovery percentage, and no wheel adds gold that was not in your concentrates. The real benefit is consistency and saved time.
Maintenance and Storage
A spiral wheel is a simple machine, and a few habits keep it running for years:
- Flush the pump with clean water after every session so fine sand does not settle in the impeller.
- Drain and dry the tub before storage, especially in freezing weather.
- Inspect the riffles for wear, cracks or residue. Built-up film can reduce how well gold climbs the spirals; a mild detergent rinse usually clears it.
- Check wiring and connectors for corrosion, since the unit works around water. Keep a spare fuse of the specified rating, and never substitute a higher one.
- Store the wheel flat or as the manual directs, out of direct sun, to avoid warping.
Frequently Asked Questions
What angle should a spiral gold wheel be set at?
Start where your manual says. Camel Mining documentation suggests about 45 degrees as a starting point. Adjust from there based on whether sand is reaching the cup or gold is reaching the tailings.
Can I put raw dirt in a spiral wheel?
No. Spiral wheels are designed for classified concentrates, not raw pay dirt. Run raw material through a sluice, trommel or screen first.
Why is gold ending up in my tailings?
Usually overfeeding, too steep a tilt, or too much water. Slow the feed first, then adjust one setting at a time.
Do I need soap in the water?
A small amount of wetting agent is recommended to keep fine gold from floating. Follow your manufacturer's guidance on type and amount.
Can a spiral wheel run off a car battery?
Camel Mining wheels are 12V DC units. A deep-cycle battery is generally preferred for long sessions; check the manual for fuse rating and current draw.
