Gold Mining Equipment Gravity Separator Machine Gravimetric Table Gemini Shaker Table

The Gemini Shaker Table (gravity separator/gravimetric table) is a gravity concentration device that separates minerals based on specific gravity differences. Fine material is fed onto a vibrating, inclined table deck while water and table motion stratify and wash particles so heavier precious metal particles (e.g., gold, palladium, tantalum, copper) concentrate and separate from lighter gangue.

The table is ideal for grain sizes between 30 microns and 2 mm. The specified maximum feeding size is ≤2 mm, so any oversize material should be crushed or screened prior to feeding.

The listed process capacity is 450–500 kg per hour. Actual throughput depends on feed size distribution, feed density, operator settings and ore characteristics.

Recommended feeding density is 10%–30% solids by weight in the feed slurry. Optimal density within that range depends on particle size and mineralogy and may require testing and adjustment.

Overall dimensions are 1490 × 894 × 1160 mm (length × width × height). Motor power is 0.75 kW. Confirm the required voltage and frequency with the supplier to match your local electrical supply.

The table deck is made of high polymer plastic, chosen for wear resistance and to provide the correct surface characteristics for efficient separation.

It is specially designed for precious and heavy metals such as gold, palladium, tantalum and copper. It can also be used for other minerals with a sufficient density contrast to the gangue.

The laboratory type is sized for smaller test runs, pilot work and assay-scale separation, while the industrial type is built for continuous higher throughput (specification above reflects an industrial capacity). Mechanical robustness, frame size and throughput are the main differences.

Frequently installed mini valves allow fine adjustment of water flow to different zones of the water collector. Operators use these adjustments to control wash water distribution and the flow pattern across the deck, optimizing stratification and separation for different feeds.

Recovery and concentrate grade depend heavily on ore type, particle size distribution, liberation, feed density and operator settings. While the Gemini Table can achieve high concentration rates for well-liberated material, specific recovery figures should be determined by testing on your ore (lab tests or pilot runs).

You will need a stable, level mounting surface, a reliable electrical supply sized for a 0.75 kW motor (confirm voltage/frequency), and a clean water supply with controllable flow. Space for feed preparation (crushing/screening) and tailings handling is also required.

Routine maintenance includes keeping the deck clean from buildup, inspecting and servicing the motor and vibration components, checking and adjusting mini valves and water lines, replacing worn deck liners or seals, and ensuring structural fasteners are tight. Follow supplier maintenance intervals for bearings and drive components.

Common consumables include table deck liners (high polymer), valve components, seals and possibly vibration drive parts. Contact the supplier for a recommended spare parts list and availability.

The unit is relatively compact but not necessarily intended as a handheld field device. It can be relocated with appropriate lifting equipment. For remote or mobile operations, confirm mounting, power source and water supply arrangements; the laboratory type may be easier to move.

Operators should use appropriate PPE (eye protection, gloves, hearing protection as needed), lock out power before maintenance, avoid loose clothing near vibrating parts, ensure safe water and electrical connections, and train staff on proper feed preparation and emergency shutdown procedures.
