Automatic Gold Mining Equipment Centrifugal Gold Gravity Concentrator

It is a Gelin centrifugal concentrator — a gravity concentration machine that uses high G-forces and pressurized water to recover gold and other high-density minerals. It is typically used in the roughing stage to recover most valuable minerals and discard barren rock.

It is suitable for recovering gold (placer and rock), tungsten, lead, manganese, iron and other high-density minerals.

For placer gold the recovery rate can be 98% or higher. For rock gold, recovery can reach about 97% when the feed particle size is below 0.04 mm.

Models include STLB20, STLB30, STLB60, STLB80 and STLB100. Combined across models the capacity range is approximately 0.2–120 t/h depending on model and feed conditions.

Across models typical power ratings run from about 0.75 kW up to 18.5 kW. Rotary speeds range roughly 360–800 r/min. Pressurized water requirements vary by model from about 1.5 to 60 t/h. Refer to the specific model technical table for exact figures.

The concentrator is designed for fine feed; best rock-gold recovery occurs when feed is finer than 0.04 mm. Feed density can be adjusted but typical operating density is up to about 50% solids by weight — check the chosen model spec for limits.

High-speed rotation generates centrifugal forces that drive heavier particles into grooves in the rotor. Pressurized tangential water creates a fluidized bed so heavy particles are trapped while lighter material flows out, enabling efficient gravity concentration.

Semi-automatic units require manual monitoring and some manual control of feed and discharge, while full-automatic units include automated feed control, discharge timing and possibly integrated PLC controls for less operator intervention and more consistent operation.

The machine is designed for simple installation and adjustment, with an integrated structure and straightforward spare parts replacement. Basic mechanical and electrical skills are sufficient for setup; full installation support can be arranged through the supplier.

Common spare parts include liners, belts, bearings, springs, rubber seats, main shafts, and motors. Keep wear parts such as liners and belts available to minimize downtime.

Yes. The concentrator operates with low noise, causes minimal dust, and does not require chemical reagents — making it an environmentally friendly option for gravity recovery.

Daily visual inspections are recommended (check feed, water lines, seals, belt tension). Clean liners and grooves after each shift or campaign depending on ore abrasiveness. Perform scheduled bearing, belt and lubrication checks per manufacturer guidance (e.g., weekly or monthly) and replace worn parts promptly.

Yes. The concentrator has a relatively small footprint and is suitable for inclusion in gravity separation circuits or used as a rougher ahead of downstream processing. Selection of the appropriate model depends on required throughput and feed characteristics.

Yes. The manufacturer has exported to countries including South Africa, Kenya, Congo, Indonesia and Pakistan. They typically offer sample testing services, model selection advice, and can customize unit configurations. Contact the sales team for quotations, lead times and factory test options.

Choose based on desired throughput (t/h), typical feed particle size and feed concentration, available water and power, and available floor space. If uncertain, provide a sample and process conditions to the supplier so they can recommend the optimal model and settings.
