Inflatable Flotation Machine

High-Capacity Air-Inflated Flotation Machines (KYF & XCF Series)

The Air-Inflated Flotation Machine (also known as a Pneumatic Flotation Cell) is the core sorting equipment used in modern, large-scale ore dressing plants. Unlike self-aspirating mechanical cells, this advanced equipment relies on an external low-pressure blower to force massive, highly controlled volumes of air into the slurry while a mechanical impeller provides continuous agitation.

This "forced air" design produces a vast quantity of highly uniform bubbles, drastically improving the probability of bubble-mineral collisions. As a result, our KYF and XCF Flotation Cells offer superior recovery rates for coarse particles, high-density minerals, and complex polymetallic ores.

Widely recognized as the mainstream Froth Flotation Equipment for non-ferrous metals (Copper, Lead, Zinc), precious metals (Gold, Silver), and non-metallic minerals, these machines can reduce your plant's energy consumption by up to 50% compared to traditional mechanical cells.

Core Advantages & Economic Benefits

• 50% Energy Savings: Because the impeller is only responsible for mixing (not sucking air), the motor size is drastically reduced. This cuts electricity consumption by 30-50% across your entire flotation circuit.
• Optimal Bubble Dispersion: The external blower and micro-porous gas distributor provide a steady, adjustable air flow. This creates highly uniform bubbles (0.8-2mm), maximizing the flotation kinetics for both fine and coarse particles.
• Reduced Chemical Consumption: The highly efficient mixing and air dispersion system ensures better contact between reagents and minerals, lowering overall chemical consumption by 10-20%.
• Extended Wear Life: The "U" type tank design eliminates dead corners, preventing sand sedimentation. Combined with high-grade polyurethane or rubber linings, the service life of the impeller and stator is extended by 40%.

How Forced-Air Flotation Works

The separation process utilizes customized reagents to make valuable minerals hydrophobic (water-repelling).

1. Slurry & Air Mixing: Chemically conditioned slurry is fed into the tank. Simultaneously, an external Roots blower forces low-pressure air down the hollow central shaft.
2. Dispersion: The large-diameter conical impeller rotates, shearing the forced air into millions of microscopic bubbles while keeping the heavy slurry in full suspension.
3. Mineralization: The hydrophobic (water-repelling) valuable minerals collide with and stick to the rising air bubbles.
4. Separation: The mineral-laden bubbles rise to the surface to form a thick, stable froth layer. Rotating scraper paddles continuously sweep this valuable concentrate into the collection launders, while the barren tailings flow to the next tank.

Model Selection: KYF vs. XCF vs. BS-K

In modern plant design, XCF and KYF cells are typically used together as a combined unit. The XCF acts as the "suction" tank (pulling slurry up from the previous stage without needing a pump), and the KYF acts as the highly efficient "direct flow" tank.
