Product Introduction: The XCFⅡ/KYFⅡ flotation machine is a further development of the XCF/KYF models. It features a deeper U-shaped trough, a hollow shaft with aerated and suspended stators, and a new impeller with backward-angled blades, resulting in low pressure head, high circulation volume, low power consumption, and a simple structure. A multi-porous cylindrical air distributor is installed within the impeller cavity to ensure uniform air dispersion. Two models are available: XCFⅡ and KYFⅡ.

I. Product Introduction

The XCFⅡ/KYFⅡ flotation cell is a further development of the XCF/KYF model. It utilizes a deeper U-shaped trough, a hollow shaft with aeration and a suspended stator, and a new impeller with backward-inclined blades at a simple structure, resulting in low pressure head, high circulation volume, low power consumption, and a simple structure. A multi-porous cylindrical air distributor is installed within the impeller cavity to ensure uniform air dispersion. Two models are available: the XCFⅡ/KYFⅡ models.

The XCFⅡ/KYFⅡ flotation cells feature either single-sided or double-sided flotation mechanisms, which can be selected based on process requirements. The differences and advantages of these two types are described below:

1. The XCFⅡ is a paddle-type aerated mechanical agitation flotation cell. It not only possesses the advantages of conventional aerated mechanical agitation flotation cells, but also features self-priming for both ore feeding (input) and ore return (return), eliminating the need for a foam pump. However, its power consumption is slightly higher than that of the KYF model. XCFII: Features slurry suction capability and can be used as a suction trough for roughing, sweeping, and cleaning operations. It should be configured in conjunction with the KYFII. A foam pump is not required for the return of the middlings.

The KYFII is a filling-type mechanical agitator flotation machine. It lacks self-priming slurry and has relatively low power. If this model is selected for flotation, the equipment requires a stepped (elevated) configuration, and a foam pump is required for the return of the middlings. To achieve a horizontal configuration of the flotation equipment, the XCFII and KYFII models can be combined, with the XCFII serving as the suction trough and the KYFII as the direct current trough. This eliminates the need for a foam pump for the return of the middlings. This maximizes the unique and complementary capabilities of each model, leveraging their strengths to overcome their weaknesses. This flotation machine features a double-inverted hammer-shaped impeller with backward-inclined blades and an air distributor located in the center of the impeller, resulting in superior performance compared to similar flotation machines. KYFⅡ: No ore absorption capability. If configured for independent operation, the front and rear operating ladders should be configured with a height difference of 300-500mm. The return of middling ore does not require a foam pump. If paired with an XCFⅡ flotation machine, the KYFⅡ can be used as a DC trough for the coarse, sweep, and fine operation sections. It can be placed horizontally, and the return of middling ore does not require a foam pump.

II. Main Features

The XCF/KYF flotation machines offer high aeration capacity, uniform gas dispersion, and low energy consumption, potentially saving 30%-50% compared to conventional flotation machines. Their simple structure makes them easy to maintain. Wear on vulnerable parts such as the impeller and stator is minimal, saving 70%-80% in costs. They offer excellent slurry circulation and low reagent consumption, reducing consumption by 10%-15%. Combined units can be configured horizontally to form a flotation circuit, eliminating the need for a foam pump. If the user requires automated slurry and flotation control, they offer a variety of control functions, including manual/automatic switching and local/centralized control. 1. Low energy consumption;

2. Excellent air dispersion;

3. Impeller acts as a centrifugal pump, keeping solids suspended in the tank;

4. Low wear and tear, low maintenance costs;

5. Start-up under load;

6. Low reagent consumption;

7. Simple structure, easy maintenance;

8. U-shaped tank reduces short-circuiting and facilitates circulation;

9. Advanced slurry level control system, easy operation and management;

10. XCF/KYF units enable horizontal flotation chamber configuration, eliminating the need for a foam pump.

III. Applications

This machine is suitable for roughing, scavenging, and concentrating flotation of metals and non-metals. The particle size range of the selected material is 0.3-0.01mm, making it suitable for flotation of coarser ores.
