Detailed introduction to the basic characteristics of flotation machine

The flotation machine is suitable for screening non-ferrous black metals and can also be used for screening non-metallic materials such as quartz and talc. This flotation machine uses a motor tripod to drive the rotating impeller. On the one hand, it forms negative pressure under the centrifugal effect, on the other hand, it inhales enough air to mix minerals and drugs, and at the same time, it prunes foam to make minerals bond with foam to form photochemical foam. Adjust the sliding height and liquid level so that the useful foam can be scraped onto the wiper.
Basic Requirements

1. Good expansion effect

The flotation machine should ensure that the mine absorbs sufficient air (some flotation machines use external air compressors) and disperse it throughout the entire tank as much as possible. The finer and more even the air, the more opportunities for mines to come into contact with natural gas, and the higher the efficiency of flotation.

2. Mixing effect

The flotation machine should ensure good mixing effect on the mine. The mineral particles do not precipitate and are suspended in the air, evenly distributed in the tank. At the same time, it is necessary to promote the dissolution of some insoluble agents, so that the agents and mineral particles can fully exert their effects.

3. The role of reincarnation activities

Cyclic activities in the square of the flotation machine may increase the contact opportunities between the mine and foam.

4. The square face value can be adjusted to continue working

In the flotation process, it is sometimes necessary to adjust the thickness of the foam layer and the mineral flow. Moreover, in production, the process from mining to light and tailings discharge is continuous.

Performance characteristics

Structural device of flotation machine: the machine is mainly composed of slurry tank, mixing device, expansion device, mineral foam discharge device, motor, etc.

1. Bearing groove: It has a gate device for adjusting the pulp mouth and pulp surface, mainly composed of a groove welded with steel plates and a gate welded with steel plates and round steel.

2. Mixing device: used for mixing mines to prevent ore from settling into the tank. Mainly composed of pulleys, impellers, and longitudinal axes, the impellers are made of wear-resistant rubber.

3. Expansion device: It consists of a suction pipe through a conduit. When the impeller rotates, negative pressure is generated in the impeller chamber, and air is sucked in through the air pump tube, dispersing in the pulp to form bubbles. This type of pulp with a large number of bubbles is quickly thrown into the sperm by the rotational force of the impeller, further refining the bubbles in the square and removing the rotational motion of the optical flow in the float, causing a large number of reasons.

4. Photochemical gun disassembly device: scrape off the foam floating on the groove, and the reducer is mainly driven by the motor, which is composed of wipers.

Machine classification

The types of flotation machines include machine hybrid flotation machines, air flotation machines, hybrid flotation machines or expansion flotation machines, and gas precipitation flotation machines.

Mechanical agitation flotation machine

The square expansion and bending of the mechanical stirring flotation machine are both completed by the mechanical mixer, which belongs to the external air self-priming flotation machine. The expansion mixer has similar suction characteristics to a pump, which can both suck in its own air and self absorb.

The characteristics of the mechanical agitation flotation machine (commonly known as Type A) are as follows: Firstly, 18 to 20 guide vanes are installed on the cover.

2、 Assembly of all components including impeller, cover, vertical shaft, intake, bearings, pulleys, etc.

Thirdly, upright wing plates are installed around the groove to prevent pulp vortices.

Inflatable agitation flotation machine

The characteristics are as follows: 1. The expansion amount is easy to adjust separately. 2. The machine mixer has minimal wear and tear. 3. Choosing indicators is better; 4. Low power consumption. 5. Significant expansion effect; 6. The internal formation of upward flow of pulp.

Inflatable flotation machine

Inflatable flotation machine: 1. Structural features: no mechanical agitator, no driving components; 2. Expansion characteristics: The expander expands, and the size of the bubbles is adjusted by the structure of the expander. 3. Mixing characteristics of foam and pulp: countercurrent mixing. Purpose: To process bold and clean ores with simple composition, high grade, and easy selection. The flotation column has a simple structure, small footprint, easy maintenance, convenient operation, and saves power.

Gas precipitation flotation machine

Gas precipitation flotation devices are mainly used for the flotation of fine minerals and the de oiling flotation of oily wastewater.
