Why the trommel leads placer mining
Alluvial gold sits in clay and gravel that must be scrubbed apart before recovery. A trommel wash plant combines screening and scrubbing in one rotating drum, handling sticky feed that blinds vibrating screens — then sluices, jigs or centrifugal concentrators catch the liberated gold.
Key parameters to define
- Gravel volume per hour and clay content of your deposit.
- Maximum rock size in the feed.
- Gold particle size: coarse nuggets vs fine flake gold.
- Water supply volume and recycling requirements.
- Mobile skid/trailer mounting for deposit hopping.
Typical configuration ranges
| Item | Common options | Indicative range |
|---|---|---|
| Capacity | Trommel diameter series | 20–200 t/h gravel |
| Recovery | Sluice + carpet, jig, centrifugal concentrator | By gold particle size |
| Mounting | Skid, wheeled trailer, stationary | By mobility need |
| Power | Electric, diesel drive | Off-grid capable |
Ranges are indicative. Recovery design must match measured gold particle size.
What a quotation should clarify
| Quotation area | Questions to record |
|---|---|
| Deposit basis | What gravel volume and clay level is capacity rated on? |
| Recovery | What gold size range does the recovery circuit capture? |
| Water | Water consumption per tonne and recycling system scope? |
| Mobility | Setup and relocation time for mobile units? |
| Scope | Pumps, sluices, concentrator and spares included? |
