There are various types of flotation machines, with differences mainly reflected in the inflation method and the structure of the inflation stirring device. According to the different inflation and stirring methods, flotation machines can be mainly divided into the following two categories:
Mechanical stirring flotation machine: This type of flotation machine uses a mechanical stirrer to inflate and stir the slurry. Its characteristic is that the stirring and inflation of the slurry are both completed by mechanical stirring devices, belonging to the category of "external gas self suction flotation machines". Its inflatable agitator has characteristics similar to the suction characteristics of a pump, capable of self sucking slurry and self sucking air. This flotation machine does not require an external special fan to inflate the slurry, making it easy to configure and operate. However, the inflation amount is small, the power consumption is high, and the wear and tear are also significant.
Non mechanical stirring flotation machine (also known as inflatable flotation machine): This type of flotation machine does not use impeller or certain subsystems as the stirring mechanism, but uses specialized equipment to forcibly suck or press air from outside the flotation machine. It can be further divided into two categories: simply inflatable and air lift. Its structural feature is the absence of transmission components and mechanical mixers. The inflation feature is carried out by the inflator, and the size of the bubbles is adjusted by the inflator. The characteristic of mixing slurry and bubbles is to mix in the opposite direction of flow. This flotation machine has the characteristics of simple structure, easy manufacturing, and low energy consumption, but the aerator is prone to calcium deposition, which is not conducive to air dispersion.
In addition, there are other special types of flotation machines, such as pressurized slurry suction gas separation flotation machines, pressurized slurry pressure gas separation flotation machines, etc., all of which have their own unique characteristics and application scenarios. In practical applications, suitable flotation machine types should be selected based on specific ore properties, flotation requirements, and economic conditions.
XCF and KYF are enforced aeration flotation machine. It has a smaller diameter of impeller, thus lower peripheral speed, saving 30%-50% of power. Because and air distributor is equipped in the tank, air is evenly dispersed. The impeller acts as a centrifugal pump, so as to make the solid particles suspending. The tank is made as U type, reducing sand settlement to the least. Due to reasonable design of the impeller structure and the impeller space,impeller wearing is even, so, the service life of the impeller and stator are extended. Model KYF is unable to spontaneously suck slurry, while has low power consumption. In contrast, model XCF has the ability to automatically suck slurry, and may be allocated horizontally without need for foam pump, but consumes more power than model KYF. Therefore, model XCF and model KYF are combined into a set, i.e., XCF as the sucking tank, and KYF as the direct tank. The combined set can be arranged horizontally without foam pump either.
Flotation cells
SF flotation machine is used for the separation of the nonferrous metals, black metals, precious metals, non-metal ore and industrial chemicals as well as other useful ore. It has the following features: large air inhalation and lower energy consumption. Every cell has air inhaled, pulp sucked and flotation three functions; a closed flotation circuit and no need any auxiliary machine. Horizontal placing is good for the change of the flow sheet and reasonable cycling of the pulp, besides, reducing the sand settlement to the least. It has the self-controlling device for the pulp and easy to adjust. Impeller has the backward blades so the upper blades bring the cocycle and under blades bring the circular.
Mechanical agitation, self air inhalation and pulp suction.
It can be combined with JJF cells to be the suction cell.
