The Lipu Mobile Trommel Gold Wash Plant is an integrated solution for washing, screening and recovering gold from alluvial and placer deposits. Built on a mobile chassis, the plant combines a feed hopper, trommel screen, water-spray system, sluice box and optional gravity-recovery equipment in one compact unit.
It is designed for projects that need practical gold washing, flexible site relocation and fast deployment without the civil work required for a fixed plant.
A Mobile Trommel Gold Wash Plant is a movable mineral-processing unit for separating gold-bearing sand, gravel and alluvial material. Raw material enters the feed hopper, is washed and screened inside the rotating trommel, then flows to a sluice box or optional gravity concentrator for gold recovery.
The wheel-mounted or towable design helps operators move the plant between riverbeds, alluvial zones and temporary mining areas. It is a practical choice for exploration, test mining and small- to medium-scale placer gold projects.
The Mobile Trommel Gold Wash Plant is suitable for:
For feed with high clay content, sticky material or a high percentage of fines, the plant can be configured with a scrubber, enhanced washing section or additional classification equipment.
As a modular front-end washing unit, the plant can integrate into a complete alluvial gold processing plant with concentrate finishing and tailings management.
Gold-bearing material is loaded into the hopper by an excavator, loader or manual feed arrangement. Water sprays loosen soil, wash fine material and guide the feed into the trommel drum.
As the drum rotates at a slight incline, material is lifted, turned and washed across the screen surface. Fine material passes through the selected screen openings, while oversize rock leaves through the end discharge.
The screened fraction flows to a sluice box or optional gravity-recovery equipment. Dense gold-bearing minerals are retained for further cleaning, while lighter material is discharged as tailings.
The feed hopper receives raw material from site equipment. An optional grizzly removes large rocks before they enter the washing and screening stage.
The rotating trommel performs washing, screening and oversize separation. Drum diameter, length and screen aperture are selected according to required capacity, feed size and cut size.
Water sprays help break up loose soil, wash material through the screen openings and reduce screen blockage. Pump capacity and spray layout can be matched to local water conditions.
The sluice box captures gold-bearing heavy minerals after screening. Riffle design, recovery mat type and sluice length can be selected according to gold particle size and recovery requirements.
The plant can be configured with additional equipment for improved concentrate cleaning or fine-gold recovery:
The integrated frame can be supplied in wheel-mounted, skid-mounted or fixed-frame configurations. Stabilizer jacks support the plant during operation and help simplify relocation.
The following models are typical configurations. Final drum size, screen aperture, water demand and power source can be customized to match feed characteristics, clay content and project capacity.
| Model | Capacity (TPH) | Drum Size (Dia. × Length) | Screen Mesh Options | Water Demand (m³/h) | Power Source / Power | Chassis Type |
|---|---|---|---|---|---|---|
| LPT-20 | 10–20 | Φ800 × 2000 mm | 2–10 mm, single or double layer | 30–50 | 7.5 kW or diesel generator | Skid or single-axle wheels |
| LPT-50 | 30–50 | Φ1000 × 3000 mm | 2–12 mm | 60–100 | 15 kW or diesel generator | Dual-axle wheels with tow bar |
| LPT-100 | 80–100 | Φ1200 × 4000 mm | 2–15 mm | 120–180 | 22 kW or 50 kVA genset | Heavy-duty mobile trailer |
| LPT-150 | 120–150 | Φ1500 × 4500 mm | 2–20 mm | 180–250 | 37 kW or 75 kVA genset | Heavy-duty mobile trailer |
The plant combines feed handling, water supply, trommel washing and sluice recovery in one mobile system for alluvial gold operations.
The integrated design is suitable for projects that move between riverbeds, alluvial zones or temporary mining locations.
The trommel combines material washing, size separation and oversize removal in a compact processing unit.
The plant can operate with a simple sluice-box circuit or include centrifugal concentration, jigs or shaking tables where finer gold recovery is required.
Screen mesh, drum dimensions, spray pressure, hopper design and recovery modules can be selected around feed size, clay content and required throughput.
Compared with a fixed wash plant, a mobile package usually requires less permanent foundation work and can be deployed more quickly.
Hopper → Trommel Screen → Sluice Box → Gold Captured in Sluice Matting + Tailings Discharge
Suitable for relatively clean, loose alluvial material and straightforward gold-recovery duties.
Hopper → Trommel Screen → Sluice Box → Centrifugal Concentrator / Shaking Table → Gold Concentrate
For fine free gold, rough concentrate collected during sluice matting clean-up can be upgraded with centrifugal concentrators and shaking tables.
Suitable for projects where fine gold requires an additional gravity-cleaning stage.
Hopper → Scrubber or Washing Section → Trommel Screen → Gravity Recovery → Gold Concentrate
Suitable for sticky or agglomerated feed that requires stronger washing before screening.
| Capacity (TPH) | Trommel Size | Trommel Motor Power | Recommended Pump | Overall Dimensions | Suggested Generator |
|---|---|---|---|---|---|
| 1–5 TPH | 0.5 × 1.9 m | 1.5 kW | 1.5 in / 4 HP | 2500 × 1000 × 1200 mm | Diesel engine or electric motor |
| 5–10 TPH | 0.8 × 1.8 m | 3.0 kW | 2.0 in / 5.5 kW | 4000 × 1250 × 2200 mm | 20 kW |

Final configuration should be selected according to feed size, clay content, gold particle size, water availability and local power conditions.

To recommend a suitable Mobile Trommel Gold Wash Plant, please provide:
What material is this plant designed for?
It is mainly designed for alluvial and placer gold deposits, including river sand, gold-bearing gravel and loose soil containing recoverable free gold.
Can the plant recover fine gold?
Yes. A sluice box can be combined with a centrifugal concentrator, shaking table or other gravity-recovery equipment when fine-gold recovery is required.
Can it process clay-rich material?
Yes. However, clay content should be assessed first. A scrubber, stronger spray system or modified washing section may be recommended for sticky feed.
How long does installation take?
Installation time depends on plant configuration, site preparation, power and water connections. The integrated mobile design helps shorten deployment compared with a fixed plant.
Can the trommel screen mesh be customized?
Yes. Screen aperture and screen-section arrangement can be selected according to the required separation size and feed condition.
Can this plant process hard rock gold ore?
It is mainly designed for alluvial and placer deposits. For primary lode ore requiring crushing and grinding, see our hard rock gold mining process.
We provide a variety of mining and processing equipment, including feeders, rock crushers, grinders, classifying and screening machines, washing machines, gravity separators, flotation machines, magnetic separators, electric separators, dewatering equipment and laboratory mineral processing equipment.
