JJF II Mining Flotation Machine with Large Slurry Circulation
Product Introduction
The JJF II Mining Flotation Machine features a guide tube and false bottom beneath the impeller to promote large-scale slurry circulation in the lower part of the flotation cell.
This circulation helps prevent mineral particles from settling at the bottom of the cell while supporting continuous air-slurry mixing during flotation.
With effective cell volumes from 1 m³ to 28 m³, the JJF II series is suitable for flotation separation of non-ferrous metals, ferrous metals and non-metallic minerals.
Key Features
- Large Slurry Circulation: The internal structure promotes continuous slurry circulation in the lower part of the flotation cell.
- Reduced Particle Settling: Large slurry circulation helps prevent mineral particles from settling at the bottom of the flotation cell.
- Guide Tube & False-Bottom Design: The structure beneath the impeller supports slurry circulation within the cell.
- Air-Slurry Mixing: The impeller and stator promote mixing and distribution of air and slurry.
- Self-Aspirating Air: Negative pressure generated during impeller rotation draws air into the flotation mechanism.
- 1–28 m³ Cell Volume: Multiple cell sizes are available for different mineral processing requirements.
Large Slurry Circulation Design
A key structural feature of the JJF II flotation machine is the guide tube and false bottom arranged beneath the impeller.
During operation, impeller rotation promotes slurry movement through the internal circulation path. Large-scale slurry circulation is formed in the lower part of the flotation cell, helping prevent mineral particles from settling at the bottom.
This design makes slurry circulation and particle-settling control important features of the JJF II flotation machine.
Working Principle
During operation, rotation of the impeller creates a vortex inside the vertical tube and guide tube. The resulting negative pressure draws air through the air inlet pipe.
The incoming air mixes with slurry in the impeller and stator area. The air-slurry mixture moves tangentially under the action of the impeller and is then converted into radial movement by the stator, allowing it to be distributed within the flotation cell.
Mineralized bubbles rise to the froth layer, where the froth product is removed by single-side or double-side scraping.
Slurry Circulation → Air Suction → Air-Slurry Mixing → Radial Distribution → Mineralized Bubble Rising → Froth Removal
