The GX Type High Efficiency Thickener is a new generation of solid-liquid separation equipment. Unlike traditional thickeners, it features a De-aeration Tank and a longer central feeding well, significantly increasing the settling speed.
With a processing capacity 3-5 times higher than ordinary thickeners, it is widely used for high-concentration tailings discharge and concentrate dewatering in Gold, Copper, and Zinc plants.
Removing air bubbles to accelerate particle settling.
Slurry first enters the external De-aeration Tank. Air bubbles attached to solid particles are removed, preventing them from floating and ensuring fast settling.
The slurry is fed deep into the tank (below the settling layer) via a long feeding well. This prevents turbulence in the overflow zone.
Flocculant is added to form large flocs. The deep sludge bed compresses the solids, achieving a higher underflow density (up to 70%).

Why upgrade to GX High Efficiency Thickener?
| Feature | GX High Efficiency Thickener | Standard Thickener (NZ) |
|---|---|---|
| Capacity per Area | Very High (2.5-5 t/m²·d). | Standard (0.5-1.0 t/m²·d). |
| De-aeration | Yes (Crucial for fine particles). | No. |
| Underflow Density | High (60-70%). | Medium (40-50%). |
| Footprint | Small (Saves space). | Large. |
Thanks to the de-aeration system and specialized feeding, one GX thickener can replace 2-3 standard thickeners, saving huge infrastructure costs.
The deep sludge bed allows for longer compression time, producing a high-density underflow ideal for filter press feeding or paste backfill.
Can be equipped with automatic flocculant dosing and rake lifting systems, ensuring stable operation even with fluctuating feed rates.
| Model | Diameter (m) | Height (m) | Area (m²) | Capacity (t/d) | Power (kW) |
|---|---|---|---|---|---|
| GX-3.6 | 3.6 | 1.7 | 10.18 | 50 - 100 | 1.5 |
| GX-5.18 | 5.18 | 2.13 | 21.0 | 100 - 200 | 4.0 |
| GX-7.5 | 7.5 | 2.8 | 44.2 | 200 - 400 | 5.5 |
| GX-12 | 12.0 | 3.6 | 113.0 | 500 - 800 | 7.5 |
| GX-18 | 18.0 | 4.4 | 254.0 | 1000 - 1500 | 7.5 |
| GX-20 | 20.0 | 4.4 | 314.0 | 1500 - 2000 | 7.5 |
A: Yes. The high efficiency of the GX thickener relies on the rapid settling of flocculated particles. A polymer dosing system is usually required.
A: Yes. The deep feeding well and large settling area provide a good buffer. However, the flocculant dosage should be adjusted automatically based on feed flow.
A: Air bubbles attached to particles act like life jackets, making them float instead of sink. The de-aeration tank removes these bubbles, ensuring solid settling.
