Next, let’s see the types of flotation machine we can supply.

What Is KYF flotation machine Used For?

KYF type inflatable mechanical agitation flotation machine (mining flotation machine) is suitable for large and medium-sized ore dressing plant roughing and selecting operations, can select non-ferrous metals, ferrous metals and non-metallic minerals, the size of the material into the range of 0.3 ~ 0.01mm (-0.074mm particle size content>50%).

For example, an African mineral processing plant wants to purchase a flotation machine equipment to process fluorite ore, requirements: large capacity, high efficiency, energy saving, and our technical staff exchanged, selected the KYF type inflatable agitation flotation machine. The innovation of this machine lies in the unique impeller-stator structure and tank form. In this application, the fluid state in the tank is reasonable, the slurry suspension state is good, the foam layer is stable, and the operation is normal and smooth, no need to discharge the ore when starting and stopping, which greatly reduces the energy consumption. The grade of the ore after sorting is generally improved, which meets the demand of the plant.

Applicable materials: copper ore, magnetic pyrite, hematite, limonite, molybdenum ore, gold ore, iron ore and so on.

Working Principle of KYF Flotation Machine

When the impeller of KYF type inflatable mechanical agitation flotation machine rotates, the slurry in the tank is sucked in between the impeller blades from all sides through the bottom of the tank from the lower end of the impeller. At the same time, the low-pressure air supplied by the blower enters the air distributor in the impeller cavity through the air duct, air adjustment valve and hollow spindle. Through the holes around the distributor into the impeller blades, the slurry and air in the impeller blades between the full mixing, by the impeller upper half of the periphery discharged. The discharged mineral flow moves upward diagonally, and is dispersed throughout the tank after being stabilized and oriented by the stator mounted diagonally above the periphery of the impeller.

Mineralization bubbles rise to the surface of the tank to form foam, foam self-flow to the foam tank, the pulp and then return to the impeller area for recirculation, and the other part of the tank through the wall of the circulation holes into the lower tank for re-selection.

Advantageous features of KYF Flotation Machine

• The impeller of the flotation machine is a kind of conical impeller with the blade tilted back at an angle, with strong mixing ability and simple structure.
• Multi-hollow cylindrical air distributor is installed in the impeller cavity, with uniform air dispersion and good air-pulp combination.
• Small impeller diameter, low circumferential speed, low power consumption, energy saving 30-50%.
• Good suspension of ore particles, high flotation index.
• Adopting U-shaped tank body, less tailing sand deposition.

• Light wear and tear of wearing parts, long life.
• Mechanical stirring type, can’t self-priming, can’t self-priming slurry, operation room need step configuration.
• It can form a joint flotation unit with XCF type flotation machine as DC tank.

KYF Flotation Machine FAQ

Q: What is the KYF flotation machine used for?
A: KYF flotation machine is widely used for separating non-ferrous metals (like copper, lead, zinc, nickel, gold), ferrous metals, and non-metallic minerals. It is suitable for roughing, scavenging, and cleaning flotation circuits.

Q: What is the capacity range of a KYF flotation cell?
A: The single-cell capacity of KYF flotation machines typically ranges from 1m³ to 680m³. Larger models like KYF-680 are designed for high-volume mineral processing plants.

Q: Does KYF flotation machine need a slurry pump or foam pump for froth recovery?
A: No. KYF flotation machine features a self-priming design for froth but does NOT self-prime slurry between cells. It usually works together with a XCF flotation machine (which has slurry self-priming ability) in a unit to avoid external pumps.

Q: What is the power consumption of KYF flotation machine?
A: KYF flotation machines are designed to be energy-efficient. For a typical KYF-100 (100m³ cell), the installed power is around 110-132 kW. Actual power consumption depends on slurry density and aeration rate.

Q: Can KYF flotation machine handle coarse particles?
A: Yes. KYF flotation machine uses a special impeller and stator design that creates strong slurry circulation and a stable froth bed, allowing it to handle coarser particles than conventional mechanical flotation cells.

Q: What materials are used for the impeller and stator?
A: The impeller and stator are typically made from wear-resistant materials such as rubber, polyurethane, or high-chrome alloys. The choice depends on the abrasiveness and corrosiveness of your slurry.

Q: How do I choose between KYF and XCF flotation machine?
A: Use KYF alone when you have an external pump to move slurry between cells. Use KYF + XCF combined as a unit when you need a self-priming circuit without external pumps. XCF can self-prime slurry from the previous cell.

Q: What is the air flow rate requirement for KYF flotation machine?
A: The air flow rate typically ranges from 0.5 to 2.0 m³ per minute per m³ of cell volume. Exact requirements depend on your mineral type and froth characteristics.

Q: How long do wear parts last on a KYF flotation machine?
A: Under normal operating conditions with medium abrasion slurry, the impeller and stator typically last 6 to 12 months. For highly abrasive ores, wear-resistant rubber or polyurethane parts can extend life to 12-18 months.

Q: Do you offer spare parts for KYF flotation machines?
A: Yes. We supply all replacement parts including impellers, stators, air distributors, shafts, bearings, and V-belt drives. We recommend keeping a set of critical wear parts in stock to minimize downtime.

Q: Can KYF flotation machine be used for phosphate or potash flotation?
A: Yes. KYF flotation machines are commonly used for non-metallic mineral flotation including phosphate rock, potash, fluorite, and graphite. The cell lining and impeller material can be customized for corrosion resistance.

Q: What is the froth depth range for KYF flotation machine?
A: KYF flotation machines typically operate with a froth depth of 300mm to 600mm. Deeper froth beds help improve concentrate grade by allowing more drainage of entrained gangue particles.
