Dewatering
Thickening Equipment
Thickening recovers process water and produces a dense underflow for tailings or further treatment. The equipment uses gravity settling to separate solids from liquid, raising solid concentration while returning clear overflow to the circuit.
Equipment in this category
A thickener selection balances throughput, underflow density, and water clarity. The range here covers high-rate, deep cone, and conventional drive configurations. Each design addresses a different duty, from fine-particle recovery to high-torque paste thickening.
The Efficient Improved Thickener suits large-scale tailings or counter-current decantation duties where high throughput is essential. Peripheral Transmission Thickener handles lighter raking loads in larger basins. For elevated underflow density, the Efficient Deep Cone Thickener produces paste-like consistency. Inclined Plate Thickener fits compact footprints with finer particle settling, while Hydraulic Centre-Drive Thickener serves smaller tonnage or retrofit applications.

What decides the selection
Start with settling testwork to define solids flux and the necessary flocculant regime for target underflow density and overflow clarity. Feed density and tailings rheology then set the rake torque and tank diameter. The interplay of these variables determines thickener type, drive size, and settling area. Where water recovery or paste consistency is critical, deep cone or inclined plate configurations often emerge from the data.
- Solids flux
- Settling testwork
- Feed density
- Target underflow density
- Overflow water quality
- Flocculant regime
- Rake torque and tank diameter
- Tailings rheology
Technical parameters
72 models across 3 machine types, as published in the Xinhai equipment application manual.
These are standard-model catalogue figures. Actual capacity, power draw and wear life shift with ore properties, feed gradation and circuit conditions. Treat them as a shortlisting aid, not as a performance guarantee for your duty. Final selection rests on testwork, flowsheet calculation and a written confirmation from the manufacturer.
