SF Flotation Machine

The SF flotation machine is a crucial piece of equipment in the field of mineral separation. It is mainly used for the separation of non-ferrous metals, ferrous metals, precious metals, non-metallic minerals, and chemical raw materials, and efficiently recovers the useful minerals therein.

This equipment possesses a series of remarkable features. Firstly, it has a large air intake volume, which enables it to provide sufficient gas for the flotation process, promoting better mixing of minerals and reagents, thus enhancing the flotation effect. Secondly, it has a low power consumption. While ensuring efficient flotation operations, it can effectively reduce energy consumption, saving production costs for enterprises. Thirdly, each cell has triple functions of air intake, pulp suction, and flotation, forming a complete flotation circuit on its own without the need for any auxiliary equipment. This integrated design greatly simplifies the flotation process, reduces the equipment footprint, and maintenance costs. Fourthly, the horizontal configuration makes the equipment more flexible in installation and layout, facilitating changes and adjustments according to different production processes. Fifthly, the pulp circulation is reasonable, which can largely reduce the precipitation of coarse sand, ensuring the uniform distribution of pulp in the cell and contributing to improving the accuracy and efficiency of flotation. In addition, there is an automatic control device for the pulp surface, which allows operators to adjust it conveniently, further optimizing the flotation process.

The impeller is equipped with backward-inclined upper and lower blades, and this unique design plays an important role in the flotation process. When the impeller rotates, the pulp in the upper and lower impeller chambers generates centrifugal force under the action of the upper and lower blades and is thrown to the surrounding areas, thereby forming a negative pressure area in the upper and lower impeller chambers. At the same time, the pulp above the cover plate is sucked into the upper impeller chamber through the circulation holes on the cover plate, forming an upper pulp circulation. When the lower blade throws the pulp to the surrounding areas, the pulp at its lower part replenishes towards the center, thus forming a lower pulp circulation. And the air is sucked into the upper impeller chamber through the air suction pipe and the central cylinder, fully mixing with the sucked pulp to form a large number of fine bubbles. These bubbles are evenly dispersed in the cell after being stabilized by the cover plate, forming mineralized bubbles. The mineralized bubbles float to the foam layer and are scraped out by the scraper as foam products, completing the flotation process.

The impeller is equipped with backward-inclined double-sided blades. This unique design can achieve double circulation of pulp in the cell, ensuring that the pulp flows and mixes fully in the cell, providing a more uniform environment for flotation.

The gap between the impeller and the cover plate is relatively large. This design significantly increases the air intake volume, meeting the demand for gas volume in the flotation process and improving the flotation efficiency.

The circumferential speed of the impeller is low, reducing the wear between the impeller and other components, extending the service life of vulnerable parts, and reducing the maintenance cost and downtime of the equipment.

The forward-inclined cell body effectively reduces the dead corners in the cell, enabling the pulp and foam to flow more smoothly. The fast movement speed of the foam helps to improve the flotation effect and concentrate quality.

It has a large air intake volume and low energy consumption, greatly reducing energy consumption while ensuring the flotation effect, demonstrating its advantages of high efficiency and energy saving.

The vulnerable parts have a long service life, reducing the frequency of equipment replacement of vulnerable parts, lowering the operating cost, and improving the reliability and stability of the equipment.

It is conducive to the flotation of coarse-grained minerals. Its unique structure and working principle can better handle coarse-grained minerals, improving the recovery rate and flotation efficiency of coarse-grained minerals.

This flotation machine adopts the working mode of mechanical agitation, self-air intake, and self-pulp suction, without the need for additional air intake equipment, and is easy to operate. In addition, it can form a combined flotation unit with the JJF flotation machine and serve as the suction cell for each operation, further expanding its application range and flexibility.

The SF flotation machine can be widely used for the separation of non-ferrous metals, ferrous metals, and non-metallic minerals, especially suitable for the roughing and scavenging operations of large and medium-sized flotation plants. Whether it is processing non-ferrous metal ores such as copper, lead, and zinc, ferrous metal ores such as iron and manganese, precious metal ores such as gold and silver, or various non-metallic minerals, it can demonstrate excellent performance, providing reliable guarantee for the ore
