Full-section air-lift microbubble flotation machine

What is Full-section air-lift microbubble flotation machine?

Full-section air-lift micro bubble flotation machine is a new generation of flotation equipment. It uses air-lift air with certain pressure to agitate the slurry, and the flotation machine itself has small agitation power, which saves energy significantly; it is installed with high-speed mixing device and atomizing device for ore, medicine and gas.

The energy-saving of the full-section air-jet device of the full-section air-lift micro bubble flotation machine is significantly improved, and the comprehensive energy-saving can reach more than 85%, while the damping device is installed to increase the flotation stroke, and the flotation effect is improved by more than 5%, and the gas-pharmacological mixer can make the air bubbles rich, and the adhesion rate of the pharmaceuticals is high, and the dosage of the pharmaceuticals can be saved by more than 20%. Full cross-section air-lift microbubble flotation machine medicine atomization feeding, large specific surface area, and the effective utilization rate of medicine is high, so the dosage of medicine is less. Air is micro bubble, large specific surface area, and the effective utilization rate of air is high. The check valves of the full-section air-lift microbubble flotation machine are made of wear-resistant rubber, which greatly improves the life of the equipment.

What Is Full-section air-lift microbubble flotation machine Used For?

Full-section air-lift micro bubble flotation machine is equipped with one or several air chambers under the tank body, and the upper cover of the air chamber is evenly covered with inflatable one-way valves, when the pressure air is given in, the one-way valves will open, and the pressure air will enter into the flotation tank, and the air entering into the tank body will become a miniature air bubbles in the ore liquid, and the ore particles will attach to the air bubbles, and the air bubbles will rise with the air bubbles and be spilt out in the overflow tank.

For example, A company originally planned to use XCF-16 and KYF-16 combined unit flotation machine and Roots fan, the total power of 745kw. After the analysis of Chunlei technical personnel, recommended this full-section air-lift flotation machine itself is not powered, it only needs fans, stirring tanks and pumps, its power is 208.5kw, saving power 72%, energy saving effect is very significant. The flotation recovery rate is increased by 5%.

Working Principle of Full-section air-lift microbubble Flotation Machine

The working principle of the full-section micro bubble flotation machine is to install numerous elastic wear-resistant rubber check valves uniformly and densely in the whole section at the bottom of the flotation machine, so that a large number of micro bubbles are generated when the pressurized air enters. These microbubbles are fully mixed with the slurry, and then enter the flotation drum and precipitate out under the sudden decrease of pressure, thus realizing the flotation of minerals.

In addition, due to the surface area of the micro bubble than large, filled with pharmaceutical materials and higher flotation tank and other factors have increased the flotation time, making the flotation effect is obvious. High-speed mixing device and atomizing device for minerals, chemicals and air are installed in both roughing and sweeping flotation machine, which accelerate the mutual attachment of minerals, chemicals and air, improve the flotation index and reduce the loss of chemicals.

Full-section air-lift microbubble Flotation Machine FAQ

Q: What is the main advantage of a full-section air-lift microbubble flotation machine over traditional mechanical flotation machines?
A: It generates much finer and more uniform microbubbles across the entire cross-section of the cell, which significantly increases the attachment probability between bubbles and fine mineral particles, leading to higher recovery rates especially for fine and ultrafine minerals.

Q: Does this flotation machine require a separate blower or external air compressor?
A: Yes, it requires a low-pressure blower. The machine uses a special air distributor and air-lift system to introduce air, unlike self-aspirating mechanical cells which suck air from atmosphere.

Q: What particle size range is most suitable for this flotation machine?
A: It is particularly effective for fine particles in the range of 10-75 microns. It performs much better than conventional machines when processing fine-grained ores such as coal fines, phosphate, graphite, and various sulfide minerals.

Q: How does the full-section air-lift design affect energy consumption?
A: It generally consumes less energy per ton of ore compared to mechanical flotation cells because it has no moving parts (rotors/stators) inside the cell. The main energy use is for the slurry circulation pump and the blower, resulting in typical energy savings of 15-30%.

Q: Is it difficult to maintain this type of flotation machine?
A: No, it is easier to maintain. Since there are no rotating mechanisms (impellers or stators) submerged in the slurry, the wear parts are limited mainly to the air distributor and pipeline. Maintenance downtime and spare parts costs are significantly lower than for mechanical cells.

Q: Can I use this flotation machine for both roughing and cleaning stages?
A: Yes, it is very versatile. It works well for roughing, scavenging, and cleaning stages. For cleaning stages, the excellent fine-bubble generation helps produce higher grade concentrates without losing fine values.

Q: What is the typical air bubble size produced by this machine?
A: The microbubble size typically ranges from 0.1 to 0.8 mm in diameter, which is about 1/3 to 1/5 the size of bubbles from conventional mechanical flotation cells. This dramatically increases the bubble surface area flux.

Q: How do I know which size or model of full-section air-lift flotation machine I need?
A: You need to provide your ore type, feed rate (tons per hour), slurry density, and desired particle size. We will conduct a lab flotation test and then scale up to recommend the correct model and number of cells for your specific application.
