The mobile jig with trommel is a portable mineral processing unit that integrates washing, screening, and separation capabilities, specifically designed for processing alluvial gold and diamonds. It combines the pre-screening function of a trommel screen or scrubber with the high-precision gravity separation of a jig. It is particularly well-suited for open-pit mining, riverbed operations, and tailings recovery, allowing for rapid deployment into production without the need for complex infrastructure.
The “mobile jig with trommel” is a combined gold and diamond processing unit that integrates a trommel screen or trommel scrubber with a jig concentrator on a single mobile platform. It first employs a rotating drum to efficiently screen and wash the raw ore, removing large waste rock and clay lumps. The qualified fine materials are then fed into a jig, where they are separated by gravity in a periodic pulsating water flow by utilizing the difference in mineral density.
Specifically, the trommel screen is suited for alluvial gold deposits with low clay content, while the lavador trómel is designed for washing and screening ores containing high levels of sticky clay. The jig separates heavy minerals from gangue based on density. Mounted on a wheeled chassis for rapid relocation, this equipment is widely used for small- to medium-scale mobile mining operations targeting alluvial deposits such as gold and diamonds.
Wheeled Mobile Chassis:
The entire unit is mounted on a towable chassis capable of wide-angle steering, allowing for rapid relocation across the complex terrain of mining sites.
Integrated Layout:
The feed hopper, trommel screen/rotary scrubber, jig machine, diesel generator set, and water pump are integrated onto a single platform, enabling immediate operation upon arrival at the site.
Wear-resistant Screen:
Features high-manganese steel woven mesh or polyurethane screen panels, and supports quick replacement of screens with different aperture sizes.
Variable-frequency Control:
Adjustable drum rotation speed and jig stroke frequency to suit different types of ore.
Hydraulic Support System:
The chassis is equipped with multiple sets of mechanical or hydraulic support legs, enabling rapid leveling on uneven terrain.
1. Highly Mobile: The unit can be installed and commissioned within half an hour of arrival at the mining site; it requires no civil engineering foundations, allowing for rapid deployment and immediate operation.
2. High Recovery Rate: This mobile jig machine, equipped with a trommel screen/ lavador trómel, delivers excellent recovery results for coarse-grained placer gold and diamonds, achieving concentrate recovery rates of up to 90%.
3. Integrated System: A single unit performs washing, screening/classification, and gravity separation, eliminating the need for intermediate material transfer and resulting in a streamlined, efficient process.
4. Strong Adaptability: Regardless of clay content or ore moisture levels, the trommel screen’s high-pressure washing and self-cleaning design effectively prevent screen clogging.
5. High scrubbing efficiency: High-pressure internal spraying combined with tumbling and kneading action achieves a clay removal rate of over 95%, effectively preventing gold particles from being lost within clay clumps.
6. Wear-resistant and durable: The drum body is constructed from high-manganese steel, while screens and jig sieve plates utilize highly wear-resistant materials; the entire unit is designed for a long service life and low maintenance costs.
7. Simple operation: Features one-touch startup and requires only 1–2 operators for normal production, saving on labor costs.
8. Independent power system: Powered by either a diesel engine or an electric motor, the unit is not restricted by local power infrastructure and can operate in remote areas lacking electricity.
9. High scalability: If the ore contains significant amounts of fine-grained gold, the system can be integrated with equipment such as shaking tables or centrifugal concentrators.
10. Highly customizable: Screen aperture, jig separator‘s stroke and frequency, and processing capacity can be tailored to specific ore characteristics, ensuring precise alignment with the requirements of different ore types.
The material first enters a rotating trommel screen/trommel scrubber, where an internal high-pressure spray system enables integrated washing and size classification. As the material tumbles forward within the drum, valuable minerals and fine sand smaller than the screen apertures pass through the mesh into a collection trough at the bottom, while large waste rock is discharged from the drum’s end. Subsequently, the fine-fraction slurry flows into a jig; using water pulsation and density differences, the system causes valuable minerals (such as gold or diamonds) to settle at the bottom while lighter gangue is discharged from the top, thereby achieving continuous, automated separation.

It is best suited for processing alluvial gold and diamond deposits.
It has a processing capacity of 1–20 tons per hour. The specific configuration depends on the material characteristics at your mine site.
The unit features a mobile, integrated design. Its footprint is customized based on requirements such as processing capacity, equipment configuration, and site conditions.
Yes. The mobile jig with trommel can be equipped with an integrated diesel generator set to provide all the power needed for the trommel screen/ore washer, jig machine, and water pumps. It is suitable for mining areas with limited infrastructure, such as those in Africa and Southeast Asia.
No. The trommel is equipped with a high-pressure spray system that continuously washes the screen surface, combined with the self-cleaning tumbling action caused by the drum’s rotation. Additionally, the setup can be replaced with a combination of a trommel scrubber and a jig separator, ensuring that even materials with high clay content do not cause clogging.
A mobile jig with a trommel is suitable for small- to medium-scale operations. At the same time, stationary jig separator lines are recommended for large-scale mineral processing projects; the mobile version offers irreplaceable flexibility.
