Gold Separator Machine

The Gold Separator Machine is a rotating drum scrubber designed to wash, disintegrate and separate gold-bearing alluvial material. The autogenous rotating drum uses pebbles/rocks and high-pressure water to scrub material, break up clays and soft oxides, retain fines for longer washing, and discharge oversize material via a screen for downstream processing.

It is optimized for alluvial gold deposits but is also effective for other heavy and valuable minerals commonly found in placer deposits (for example tin, tungsten, columbite, and similar dense minerals). Suitability depends on material characteristics and downstream separation methods.

Maximum feed size is model-dependent. In general the line is engineered to accept large material and can handle feed sizes up to approximately 230 mm (model-dependent). Check the specific model spec for exact limits.

Capacity varies by model and feed characteristics. Typical machine models process roughly from about 30 t/h on smaller units up to around 160–180 t/h on larger units. Exact throughput depends on feed size, material composition, and operation settings.

The machines are designed to operate with a high-pressure water flushing system. Typical recommended water pressure is in the range of about 0.4–0.5 MPa, though exact requirements should be confirmed per model and site conditions.

Each unit is driven by a single high-output electrical motor coupled to a gear system to deliver efficient torque. Motor power varies by model; consult the model specifications for exact kW ratings and electrical supply requirements.

Primary wear parts include the drum liners (if fitted), the screening plate at the drum exit, rollers, and bearing seals. Replacement intervals depend on abrasive nature of feed and operating hours; inspect wear parts regularly and replace them at the first signs of excessive thinning, perforation or reduced screening efficiency.

The machine features thickened steel plate construction and heavy-duty components (bearings, gears, rollers) to withstand harsh mining environments. It is built for longevity but durability will depend on operation practices and maintenance.

Routine maintenance includes daily visual inspections, lubrication of bearings and gearboxes as per schedule, checking and tightening fasteners, cleaning high-pressure water nozzles and drum interior, checking screen integrity, and monitoring motor temperature and vibration.

The shell design is compact and requires less supporting mass than conventional roller-supported units, reducing installation footprint and foundation work. Still, a stable, level foundation and access to power and pressurized water are required. Refer to the installation manual for anchor bolt patterns and lifting points.

Yes. Many parameters (drum length/diameter, screen aperture, motor rating, feed inlet configuration and auxiliary piping) can be customized to match specific feed characteristics and throughput requirements. Discuss your site conditions with the supplier for configuration options.

Standard safety precautions include lockout/tagout before maintenance, guarding around moving parts (drum, gears, belts), electrical protection, safe access for inspection, and wearing appropriate PPE (gloves, eye protection, hearing protection). Ensure operators are trained on startup/shutdown and emergency stop procedures.

Common issues include poor recovery (adjust feed distribution, water flow, drum speed and retention time), drum clogging (increase water pressure, clean nozzles, inspect screen), excessive vibration or noise (check bearings, rollers, alignment), and motor overheating (reduce duty cycle, check ventilation and electrical supply). Consult the troubleshooting section of the manual for model-specific procedures.

Spare parts for wear items and critical components are typically available from the manufacturer or authorized dealers. Most suppliers provide after-sales support, maintenance guidance and parts provisioning—confirm lead times and warranty details at purchase.

By thoroughly scrubbing and washing material and separating oversize from fines, the drum increases liberation of gold and heavy minerals and improves the effectiveness of downstream concentration or sluicing circuits. Final recovery still depends on downstream equipment, sluice design, and process controls.
