Extraction Agitator

Extraction agitator, also known as mixing tank stirring system, is core process equipment for extraction mixing stage, ore leaching section and reagent preparation system in copper hydrometallurgy. The complete unit consists of four key parts: explosion-proof motor & reducer assembly, vertical support frame, extended anti-corrosion stirring shaft and stainless steel impeller. Mechanical stirring realizes sufficient mixing and reaction between liquid-liquid and liquid-solid materials. Our agitators are widely applied in mixing chambers of copper solvent extraction boxes, acid leaching tanks, waste liquid neutralization tanks and reagent preparation vessels. No vertical mechanical agitator is required for main electrowinning cells. Equipped with corrosion-resistant materials and explosion-proof motors, our products can operate stably long-term under corrosive media such as acidic leachate and organic extractants.

Improve Extraction Efficiency & Copper Recovery Rate Optimized impeller flow field and stable rotating speed promote full contact between aqueous leachate and organic extractant, strengthen copper ion mass transfer, reduce loss of valuable metals and stabilize recovery indicators of the whole extraction line.

Corrosion & Abrasion Resistance for Harsh Acid Working Conditions All shaft and impeller components contacting medium are made of stainless steel with excellent acid resistance and slurry scouring resistance. Longer service life reduces spare parts replacement frequency and maintenance downtime cost.

Explosion-Proof High-Torque Drive for Long-Term Continuous Operation Matched with explosion-proof motors and hard-tooth reducers dedicated to hydrometallurgical working conditions. Sufficient torque output prevents overload stall under high-solid slurry, supporting 24/7 non-stop production in smelters.

Factory Pre-Assembled Delivery to Simplify Field Installation All components are pre-assembled and tested inside the factory. The whole set of frame, drive unit, stirring shaft and impeller are delivered as integrated packages, cutting field assembly time and avoiding operation faults caused by on-site assembly deviation.

• Custom Anti-Corrosion Stirring Shafts 

1. High-Strength Cast Steel Support Frame Integral cast steel forming with high-precision flange processing. The hollow design ensures structural rigidity while facilitating later maintenance of bearings and seals. Pre-installed bearing seats guarantee high coaxiality with low vibration and noise during operation.
2. Explosion-Proof Gear Reduction Drive System Standard chemical explosion-proof motors meet safety requirements for volatile media in extraction workshops. Hard-tooth reducers feature strong load resistance and support variable frequency speed regulation according to material concentration.
3. Custom Extended Anti-Corrosion Stirring Shaft Shaft length is customized according to the actual depth of customer extraction and leaching tanks with integral passivation anti-corrosion treatment. The structure maintains good rigidity in deep liquid environments without bending during long-term operation.
4. Optional Multiple Types of Stirring Impellers Flat-blade and pitched-blade impellers are optional to meet different process requirements including extraction homogenization mixing, solid suspension anti-sedimentation and reagent dissolution preparation.
