Innovative Impeller and Stator Design for Superior Flotation Performance
Our flotation impeller and stator system is purpose-built to deliver exceptional turbulence, effective mixing, and ultra-fine air bubble dispersion – all critical factors in achieving maximum mineral recovery and process efficiency.
The impeller features an optimized blade geometry with carefully calculated curvature on both the pressure and suction sides, ensuring efficient energy transfer and uniform slurry agitation. The vertical blade profile and chord width distribution are tailored to maintain high shear rates while avoiding cavitation or the formation of oversized bubbles. Air is introduced through a central plenum and distributed evenly via multiple levels of precision-engineered channels, ensuring consistent gas dispersion across the entire flotation volume.
The stator design complements the impeller, with fixed blades that stabilize flow, reduce swirl, and maintain an optimal bubble/slurry contact environment. This synergy between impeller and stator ensures high mixing efficiency, improved particle-bubble contact, and consistent flotation performance.
Why choose our design?
- Higher recovery rates – Ultra-fine bubbles maximize the surface area for particle attachment.
- Improved energy efficiency – Geometry minimizes hydraulic losses and optimizes air-to-slurry mixing.
- Operational stability – Even gas distribution and stator-assisted flow control deliver consistent performance.
- Durability and reliability – Polyurethane construction with internal steel reinforcement ensures long service life under abrasive conditions.
- Tailor-made performance – We design and manufacture each impeller and stator exactly to the customer’s specific requirements, using advanced AI-driven simulation and optimization tools to ensure optimal performance for each ore type and plant configuration.
This combination of advanced fluid dynamics, robust materials, and AI-enhanced engineering makes our flotation mechanism the optimal choice for operators seeking both technical performance and long-term cost efficiency.
Flexible Stator Mounting Solutions
The stator can be installed in two different ways, depending on the plant’s requirements:
Suspended Mounting
- The stator is attached from above, making it extremely easy to remove the entire mechanism for maintenance without draining the flotation cell.
- This solution simplifies servicing and significantly reduces downtime.
Bottom-Mounted Installation
- The stator is fixed directly to the bottom of the flotation cell, a solution that is easier to install and requires fewer structural modifications.
- The downside is that the cell must be drained to dismantle the stator, which can increase maintenance time.
By offering both mounting options, we provide our customers with the flexibility to choose the solution that best suits their plant and operational conditions.
With this mechanism, we ensure the optimal separation of valuable minerals and an operational economy that delivers a high return on investment.
