Flotation Cell Product Introduction
Flotation machine is the also called flotation concentrator, which refers to the mechanical equipment that completes the flotation process. In the flotation machine, the ore pulp treated by adding reagents is stirred and aerated to selectively fix some of the ore particles on the bubbles. It floats to the surface of the ore pulp and is scraped out to form a foam product, and the rest remains in the ore pulp In order to achieve the purpose of separating minerals.
The flotation machine is mainly used to separate non-ferrous metals such as copper, zinc, lead, nickel, gold and so on. It can also be used for the rough selection and selection of ferrous metals and non-metals.
There are many structural forms of flotation machines. The most commonly used flotation concentrator is mechanical agitated flotation machines and froth agitation flotation machine.
Mechanical Agitated Flotation Machines
The mechanical agitation flotation machine has the earliest development and in-depth research. It has complete specifications and rapid development. It is widely used in flotation machine production practices in the world. In China flotation plant, the mechanical stirring type flotation machine used includes XJK type flotation machine, Mikhanoble type flotation machine (called A type), rod type flotation machine and so on.
XJK type (also known as A type, XJ type) flotation machine, also known as mining mechanical agitation flotation machine. It belongs to a kind of air self-absorption mechanical agitation flotation machine with radiant impeller, the mechanical type used to be in 1950 The type introduced by the Soviet Union is relatively old. Although it has been improved, the basic structure has not changed. In recent years, it has been replaced by some new flotation machines. Due to historical reasons, its application was earlier. It is still widely used in China and has already formed a series of products.
XJK series flotation machines are mainly used to separate gold, silver, copper, iron, lead, zinc, molybdenum, nickel, aluminum and other metal minerals. It is widely used in the separation and recovery for fine minerals of ferrous metal, precious metal, nonferrous metal, non-metallic minerals, rare metal, non-metal, etc.
Air-filled agitated flotation machine (SF)
The air-filled agitated flotation machine is equipped with a mechanical stirring device. And a fan with external characteristics is used to force air in. The mechanical stirring device generally only plays the role of stirring the slurry and distributing the air flow. The air is mainly pressed into the slurry by an external fan, and aeration and stirring are separated.

The Working Principle of XJK Flotation Machine
The flotation concentrator is driven by the V-belt drive of the motor to rotate the impeller, which produces a centrifugal effect to form negative pressure. It sucks in sufficient air to mix with the pulp and stirs the pulp and the medicine. At the same time refines the foam so that the mineral is bound to the foam. Float to the pulp surface and then form mineralized foam. Adjust the height of the gate to control the liquid level, so that the useful foam is scraped out by the scraper.
The Working Principle of SF Flotation Machine
The slime and medicament are fully mixed and fed into the bottom of the first chamber of the flotation machine. After the impeller rotates, negative pressure is formed in the wheel cavity. So that the slurry under the bottom of the tank and in the tank is separated by the impeller. The lower suction port and the upper suction port enter the mixing zone, which also makes the air enter the mixing zone along the air guide sleeve. The pulp, air and medicament are mixed. Under the action of the centrifugal force of the impeller, the mixed ore pulp enters the mineralization zone. The air forms bubbles and is pulverized. It fully contacting the coal particles to form mineralized bubbles, which are evenly distributed in the tank under the action of the stator and the turbulence plate Cross section. And move upward into the separation zone, enriched to form a foam layer. It is discharged by the foam scraping mechanism to form a clean coal foam. The unmineralized coal particles on the bottom of the tank will be mixed, mineralized and separated again through the circulation hole and the upper suction port. Part of the slurry at the bottom of the tank, which is not sucked by the impeller. It enters the bottom of the second chamber through the middle ore box buried in the slurry. After all the processes in the first chamber are completed, it enters the third chamber. The flotation machine repeats this cycle. And the slurry passes through the last after one room, it enters the tailings box to discharge the final tailings.
Advantages and Features
XJK Floating Machine
Strong stirring power
The consumption of medicament is less
It can handle coarse-grained and larger-density ore
Adapt to complex processes
Wide range of applications
There are 18-20 stator on the cover. These blades are arranged obliquely and form an angle of 60° with the radius. They are used for guiding the slurry flow thrown by the impeller. There are 18-20 circulation holes between the two guide blades on the cover plate for the circulation of the pulp, which can increase the aeration volume.
The gap between the impeller and the guide vane of the cover plate is generally 5-8mm. Too large a gap will adversely affect the air intake and power consumption. Usually the impeller, cover plate, main shaft, air inlet pipe and air pipe and other inflatable mixing parts are assembled into an integral part. The impeller and cover plate can be assembled concentrically to ensure that the gap between the impeller and the cover plate guide blade meets the requirements and is convenient Overhaul and replacement.
In the lower part of the air cylinder, there is a circulation hole for adjusting the circulation volume of the slurry. The ram is used to control the circulation volume.
SF Floating Machine
Large air intake and low power consumption.
Each chute has the triple functions of air suction, slurry suction and flotation. It forms its own flotation circuit without any auxiliary equipment. The horizontal configuration is convenient for process changes.
The slurry circulation is reasonable, which can minimize the precipitation of coarse sand.
Equipped with automatic control device for pulp surface. It’s easy to adjust.
The impeller has backward-inclined upper and lower blades. The upper blade produces an upward circulation of the slurry, and the lower blade produces a downward circulation of the slurry.
