BF flotation machine

What is BF flotation machine?

BF flotation machine, also known as BF type mechanical agitation flotation machine, is a multifunctional flotation equipment.BF flotation machine is divided into type I and type II, type I refers to SF type improved design, type II refers to JJF type improved design, type I is the suction tank, type II is the DC tank, usually referred to as BF type.

If you are a beginner and do not know about flotation machine, tell us your raw material characteristics, finished product requirements, site conditions, production budget, hourly production, and other requirements, we have professional engineers to equip you with a suitable model at a reasonable price. Next, let’s see the types of flotation machine we can supply.

What Is BF flotation machine Used For?

BF type flotation machine is suitable for the separation of ferrous metals, and can also be used for non-metals such as fluorite, talc, more widely used in the separation of gold, silver, copper, iron, tungsten, lead, zinc, tin, molybdenum, nickel, tantalum, niobium, manganese ore and other nonferrous metals, but also can be used for ferrous and non-metallic roughing and selecting.

For example, An iron ore flotation plant purchased BF type flotation machine from Chunlei, and its indexes are better than 5A flotation machine, and the single capacity saves 23.96% of electricity. In the case that the grade of iron rough concentrate selected by the plant is lower than 20%, the iron metal recovery rate is increased by 6.58% through the reelection of BF flotation machine and the energy consumption is reduced by 15-30%, which avoids a series of unnecessary waste of resources, and saves costs for the plant.

Applicable materials:BF type flotation machine can be widely used in the separation of non-ferrous metals, ferrous metals, and non-metallic minerals, and is suitable for roughing and sweeping operations in large and medium-sized mineral processing plants.

Working Principle of BF Flotation Machine

When the impeller rotates, the slurry in the upper and lower impeller chambers is thrown around by centrifugal force under the action of the upper and lower blades, so that a negative pressure zone is formed in the upper and lower impeller chambers. At the same time, the slurry in the upper part of the cover plate is sucked into the upper impeller cavity through the circulating holes on the cover plate, forming the slurry upper circulation. When the lower impeller throws out the slurry in all directions, the slurry in its lower part replenishes to the center, thus forming the lower circulation of the slurry. And the air through the suction pipe, the center cylinder is sucked into the upper impeller cavity, and was sucked into the slurry mixing, the formation of a large number of small bubbles, through the cover plate flow stabilization, uniformly dispersed in the tank, the formation of mineralized air bubbles. The mineralized bubbles float up to the foam layer and are scraped out by the scraper, which is the foam product.

The structure of BF type flotation machine is shown in the figure, which is mainly composed of impeller, cover plate, main shaft, center cylinder, tank body, etc. The whole impeller structure is installed in the tank body. The whole impeller structure is mounted on the main beam of the tank body and driven by the electric motor through the triangle belt. The structure of this machine is characterized by the fact that the impeller consists of a closed double truncated cone, which can produce a strong downward circulation of the slurry. This machine can also be equipped with self-control device for slurry to adjust the liquid level.

Advantageous features of BF Flotation Machine

• The impeller of the BF flotation machine consists of a closed double truncated cone, which produces a strong under-circulation of the slurry.
• Large suction capacity and low power consumption.
• Each tank has the triple functions of suction, slurry suction and flotation, forming its own flotation circuit without any auxiliary equipment, and horizontal configuration, which is convenient for the change of flow.
• The slurry circulation is reasonable, which can reduce the precipitation of coarse sand.
• It is equipped with self-control and electric control device of slurry surface, which is convenient for adjustment.
