The flotation machine originated in the Ming Dynasty of my country in the early days. At that time, the flotation machine was mainly used to process drugs and metallurgy. It used the hydrophobicity of the mineral surface to purify mineral drugs such as cinnabar and talc, so that mineral fine powder floated on the water surface. , and separated from the sinking gangue. By the end of the 19th century, the demand for metallic minerals was increasing. In order to further improve the selection of minerals, flotation methods were clearly proposed.

With the development of the times, the types of flotation machines are becoming more and more diversified. Their classification is mainly based on the different aeration methods and stirring methods, the different stator and rotor structures of the flotation machine, and the shape of the tank. Classification is based on differences in depth, movement and circulation of the slurry in the tank, entry into the flotation tank, and discharge of foam products. Based on the above situation, flotation machines are divided into four major categories:

1. Mechanical agitation flotation machine

The main features of mechanical agitation flotation machine are slurry aeration and stirring All are realized by mechanical agitators, which can self-prime air (air is sucked in near the mechanical stirring device at the bottom of the flotation tank) and self-prime slurry. In the flotation production line, the intermediate product does not need to be transported by a sand pump when returning. Therefore, this type of flotation machine can highlight its superiority and flexibility in process configuration, and because it can absorb air by itself, it does not require an external fan to aerate the slurry.

According to different models, it can be divided into: xjk type mechanical stirring flotation machine (often called A-type flotation machine in the processing plant), SF type mechanical agitation flotation machine, jjf type mechanical agitation flotation machine and xjb rod flotation machine, etc.

2. Inflatable agitated flotation machine

The main difference between an inflatable agitated flotation machine and a mechanical agitated flotation machine is that the inflatable flotation machine is an external air supply. The agitator only plays a stirring role, and the air is forced in by an external fan.

As the air is supplied by an external blower, the aeration amount can be adjusted through valves according to the needs of flotation. The impeller only plays a stirring role, and the speed is low, so the stirring is not easy. It is very strong, and the flotation of brittle minerals is not prone to sludge. The slurry surface is relatively stable, and it is easy to form a stable foam layer, which is conducive to improving the separation index. Because the impeller speed is low, the slurry flows by gravity, so the unit processing capacity is It has low power consumption, long service life, and low equipment maintenance costs.

Because the inflatable agitation flotation machine cannot self-aspirate, the intermediate product needs to be transported by a sand pump when returning. In addition, additional air equipment is required, which makes management cumbersome. Therefore, this kind of flotation machine is often used for processing Simple ore roughing and sweeping operations.

According to different models, it can be divided into: kyf inflatable agitated flotation machine, xcf inflatable agitated flotation machine, bs-k inflatable agitated flotation machine, clf inflatable agitated flotation machine, etc.

3. Flotation column

The flotation column is a type of inflatable flotation machine. Its main feature is that it has no mechanical agitator and no transmission parts. The aeration of the slurry mainly relies on External air compressor presses in.

The structure and process flow of the flotation column are simple, the machine consumes less power, has fewer wearable parts, and is easy to operate and manage. However, when the flotation column is used to process alkaline slurry, the aerator will be clogged due to calcium formation, thereby damaging the production process. Therefore, the flotation column is more suitable for roughing and sweeping operations of easy-to-select ores with a simple composition and high grade. .

4. Gas precipitation flotation machine

Gas precipitation flotation machine is also called a variable pressure or step-down flotation machine. Its main feature is that it can precipitate from the solution. Lots of foam. The main equipment includes jet flotation machine and cyclone flotation machine.

The above are the common categories of flotation machines at present. If you want to know more about flotation machines and quotations, you can contact Xinhai Mining Equipment at 15311826613!
