Domestic flotation equipment flotation machine classification introduction

At present, there are dozens of flotation devices at home and abroad, and their classification methods are also inconsistent. However, the flotation machines used in actual production are divided into four basic types according to their different aeration and stirring modes:
(1) Mechanically agitated flotation machine. This type of flotation machine is based on a mechanical stirrer (rotor and stator group) to achieve the aeration and agitation of the pulp. Domestic names: XJK type (A type), JJF type, XJQ type, SF type, JQ type, rod type and ring elbow flotation machine. Foreign names: FW type (Fallenwald), WEMCO type (Wimco), ΦMP type (Michnoble), WN type (Valman) and so on.
Advantages: Self-priming air and pulp, no need for external air device; easy to realize self-flow, easy configuration and operation when the mine returns.
Disadvantages: Small aeration, high energy consumption, large wear and so on.

(2) Inflatable mechanical flotation machine. This type of flotation machine is agitated by a mechanical stirrer to rotate the slurry and the air is inflated externally. Domestic names: CHF-XJ4m3 type, XJC type, XJCQ type, LCH-Z, X type, KYF type, JX type, etc. Foreign names: AG type (Aketaier), MX type (Marx Weir), Denver D-R type, BFP (Sara) and so on. Advantages: Large aeration, adjustable air volume, low wear, low power consumption.
Disadvantages: no suction and suction capacity, inconvenient configuration, need to increase the pressure fan and slurry return pump.

(3) Inflatable flotation machine. This type of flotation machine is characterized by neither mechanical stirrer nor transmission mechanism, it is by external air source to send compressed air to inflate and agitate the pulp. Can be subdivided into two categories: simple inflatable and airlift: simple inflatable domestic name: flotation column. Simple inflatable foreign name: CALLOW type (Carlo), WACLNTOSH type (Maglon Tor) and so on. Airlift Foreign Names: SW Type (Shallow Gas Lift), EKOF (Ecove), etc.
Advantages: simple structure, easy production, low energy consumption, large unit volume consumption.
Disadvantages: The inflator is prone to fouling, which is not conducive to air dispersion; there is a stirrer, float selection index is affected

(4) Gas-folding type (variable pressure type) flotation machine. This kind of flotation machine is a method that changes the gas pressure in the ore slurry to allow the gas to fold out a large amount of microbubbles from the slurry and stir the slurry. Can be subdivided into two categories: pumping pressure and pressure. Domestic name: XMP type (jet swirl type). Foreign name: ELMORE type (Elmore), COPPe type (Kepo), etc.
WEDAG, DAVCRA, etc.
Advantages: Large amount of aeration, fast flotation speed, large amount of processing, low energy consumption, and small footprint.
The type of flotation machine, according to its tank layout, can be divided into deep tank battle shallow trough flotation machine; according to the expulsion system foam products can be divided into scraper type, self-flooding flotation machine.
Following the actual progress in flotation research, the flotation equipment has been inexhaustibly progressed. According to the principle of operation, the existing flotation equipment can be divided into three categories, namely, the mechanical stirring flotation equipment, flotation column warfare reactor/separator type Flotation equipment. The mechanical flotation machine can be divided into self-priming flotation machine and gas-fighting mechanical stirring flotation machine according to the inflating system. The common characteristic of this kind of flotation equipment is that it is equipped with a machine stirrer. For those two types of flotation equipment research is also more in-depth, so its specifications are complete, less dead faster; flotation column belongs to inorganic mixer flotation equipment, in the past years, followed by flotation in-depth discussion of the new battle With the presentation of materials and styles, the discussion of flotation columns has become a hot surface of deposits. Many studies have been conducted on the flotation columns in the national table, and the necessary obedience has been obtained, and the rooting of the reactor/separator flotation equipment has been completed. Similar to the flotation column, the inflator is placed inside the column, and the column is used as a footer to fully control the open force field. The flotation equipment has a high flotation rate and good performance. It's a good prospect. Flotation process, flotation machine
