The Flotation machine stator rotor is a device that is easy to wear in the flotation machine, and it needs to be replaced frequently in the production practice of the concentrator. The floatation machine rotor produced by Hebei Jiding Environmental Protection Technology greatly prolongs its replacement cycle, which is a major leap forward in flotation machine technology.
In the mechanically agitated flotation machine, the mixing of the ore pulp and the flotation agent, the suspension of the ore pulp, and the dispersion of air bubbles are all accomplished by the strong rotation of the flotation machine rotor in the ore pulp. The strong rotation of the rotor causes the rotor to collide violently with the solid particles in the ore pulp. Therefore, the rotor wears greatly. In addition, as the rotor wears, it may happen:
① Insufficient mixing of flotation reagents and ore pulp results in increased dosage of reagents, increased flotation cost, and poor flotation index.
② Incomplete or uneven stirring of the slurry, the turbulence of the slurry sink or foam layer is increased, and the flotation index is reduced or scrapped.
③ The number of bubbles is reduced, the degree of dispersion of the bubbles is reduced, resulting in a reduction in the recovery rate in the flotation index. It can be seen from this that in order to achieve the desired level of flotation, a wear-resistant flotation machine rotor must be used to reduce the wear of the flotation machine rotor, and it needs to be replaced regularly.
The flotation machine stator is commonly known as the flotation machine impeller cover plate, guide vanes, flotation machine conical cover, etc. The role of the flotation machine stator in flotation is mainly to form negative pressure suction, adjust the amount of ore pulp entering the rotor, make the flotation machine easy to start, and stabilize the foam layer.
When the self-aspirating mechanical agitation flotation machine works: the ore feed pipe feeds the slurry to the center of the stator, the centrifugal force generated by the rotation of the rotor throws the slurry out, and at the same time, a negative pressure is formed between the rotor and the stator, so the inlet pipe automatically Breathing outside air. The strong stirring effect of the rotor allows the ore pulp and air to be fully mixed, and the air flow is divided into many fine bubbles. Furthermore, some bubbles will also be precipitated from the slurry behind the rotor. When all mechanical agitating flotation machines are working, the slurry and the stator of the flotation machine will have a violent impact, so the stator of the flotation machine is easily corroded.
Floater stator is usually made of metal, wear-resistant rubber and other materials. Among them, wear-resistant rubber has the characteristics of small quality and corrosion resistance, and it is constantly replacing the stator of the flotation machine of metal materials. Among them, the success of the wear-resistant rubber flotation machine stator belongs to Chai Shang Trading Co., Ltd., which belongs to the high-strength flotation machine stator.
