Deep Cone Thickener
Capacity: 5-2600 m³/h
Feeding Size: 0–300 μm
Discharging Size: 40–75% solids
Handling Materials: Tailings dewatering, concentrate concentration, sludge dewatering, etc
Deep cone thickener concentrates slurries (0–300μm) to 40–75% solids via gravity and flocculation, handling 5–500m³/h. Its steep cone design accelerates settling, producing clear overflow (<500ppm SS) and dense underflow. Ideal for tailings dewatering but requires pre-screening of >0.5mm particles.
Advantages
01.
High Density Underflow
Achieves 60–75% solids in underflow via steep cone geometry and optimized floculation, reducing downstream drying costs by 30–50%.
02.
Clear Overflow
Produces effluent with <500ppm suspended solids (SS), meeting reuse/discharge standards without additional filtration.
03.
Energy Efficient
Consumes only 0.5kWh/t solids, 60% less than centrifuges, thanks to gravity-driven settling.
04.
Compact Footprint
Deep cone design reduces diameter by 40% versus conventional thickeners for equivalent capacity (5–500 m³/h).
How Does A Deep Cone Thickener Work
1. Floculated Feed Entry: Dilute slurry (10–30% solids) is mixed with floculant (5–50 g/t) and injected into the thickener’s center well, where polymers bind fine particles into aggregates.
2. Gravity Settling: Dense flocs sink rapidly through the steep cone (55–60° slope), while clarified water rises to overflow launders (<500 ppm SS).
3. Compression Zone: Thickened solids are compressed by the cone’s narrowing geometry and rotating rakes (0.1–1 RPM), reaching 60–75% density.
4. Controlled Discharge: Underflow pumps extract concentrated slurry, with bed-level sensors automatically adjusting discharge rates to maintain optimal residence time.
