High-Efficiency Agitation Tank

Uniform Mixing, Zero Sedimentation

The impeller and baffle system is engineered to generate strong axial and radial circulation currents throughout the full tank volume, keeping all solid particles in uniform suspension regardless of slurry density fluctuations at the inlet. This eliminates dead zones at the tank bottom where dense particles would otherwise settle, ensuring consistent slurry concentration and reagent contact time for every particle passing through the leaching or conditioning circuit.

High Mass Transfer Efficiency for Leaching Applications

In cyanide leaching and acid leaching applications, the turbulent mixing environment created by the impeller system maximizes the contact frequency between ore particles and leaching reagent molecules, accelerating the dissolution reaction rate and improving metal recovery compared to low-agitation or static leaching systems. The impeller speed and geometry are optimized for each ore type and reagent system to achieve maximum leaching efficiency at minimum energy consumption.

Corrosion-Resistant Construction for Aggressive Chemical Environments

Tank internals in contact with cyanide solution, acidic leach liquor, or other corrosive process fluids are protected by thick rubber lining, epoxy coating, or fabrication from 304/316L stainless steel depending on the chemical aggressiveness of the application. The impeller blades and shaft are available in rubber-coated steel, stainless steel, or polyurethane-coated configurations to match the corrosion and abrasion requirements of each specific process.

Flexible Volume & Impeller Configuration

Working volumes from 1 m³ to 320 m³ and a choice of single-stage or multi-stage impeller arrangements allow XINGAONAI Agitation Tanks to be sized precisely for any plant throughput from small-scale pilot operations to large commercial processing plants. Multiple tanks are commonly connected in series to form a leaching train, with retention time in each tank controlled by slurry feed rate and tank volume to optimize leaching kinetics and overall metal recovery.

Energy-Efficient Drive System

The impeller geometry and rotational speed are optimized to achieve the required mixing intensity at minimum shaft power input, reducing energy consumption per tonne of slurry processed compared to oversized or poorly matched impeller designs. Variable-frequency drive (VFD) control is available as an option, allowing impeller speed to be adjusted in real time to match varying slurry density and viscosity conditions without mechanical drive changes, further reducing energy consumption during periods of reduced throughput.

Low Maintenance, Long Service Life

The upper bearing assembly uses sealed, grease-lubricated heavy-duty bearings with extended re-greasing intervals, accessible from outside the tank without draining. The impeller blades are bolted to the hub in replaceable segments, allowing individual worn blades to be swapped during scheduled maintenance without removing the entire shaft assembly. Rubber-lined tanks and rubber-coated impellers in cyanide leaching service typically achieve 5–8 years between major relining overhauls under normal operating conditions.
