In recent years, when designing a Portable Impact Crusher Plant For Sale In Indonesia , great attention has been paid to the generation of microbubbles, so what does microbubbles refer to? Under standard conditions, the solubility of air in water is 2%, and we all know that when the pressure drops, the gas dissolved in the liquid will precipitate from the solution in the form of bubbles, called active microbubbles. It is called active microbubbles, because microbubbles have the advantages of small diameter and high dispersion, and microbubbles can selectively precipitate on the surface with higher hydrophobicity. So what factors will affect the precipitation of microbubbles? Let's take a look together.

1. Solubility of air
The first point is the solubility of air. The solubility of air refers to the saturation of air in the pulp at the beginning. As the solubility of the gas becomes smaller, more gas escapes the water, and microbubbles increase.
2. Degree of pressure reduction of pulp
In fact, during the operation, there are many opportunities for the pulp to dissolve in the air. For example, these processes such as stirring and pumping will promote the dissolution of the pulp. There are many reasons for the pressure drop of the pulp, such as the spraying of the pressure pulp and the pulp from the bottom of the tank. When moving to the top of the tank, the pressure at the trailing edge of the impeller blades is reduced, and the pressure fluctuations and reductions caused by the impeller throwing out the pulp will cause the pulp to depressurize. When the pressure of the pulp increases, there will be more Bubble precipitation, which also makes modern jet flotation machines use pulp pressure.

3.The core of microbubble precipitation
'Core' refers to the hydrophobic surface of the mineral. When there is 'core', microbubbles can preferentially precipitate out of these 'cores'. Therefore, in general, the more 'cores', the more favorable the microbubble precipitation, especially if the micropores, cracks and gaps on the surface of the hydrophobic ore particles are filled by gas molecules, this phenomenon is called gas Sprouts, they become the 'core' of the microbubbles. Therefore, the precipitation of the hydrophobic ore particles of the pulp and the microbubbles are complementary and interact, because the presence of the hydrophobic ore particles in the pulp will greatly improve the conditions for the precipitation of the microbubbles. On the other hand, the precipitation of the microbubbles strengthens the hydrophobicity. Flotation of Sexual Ore.
