Guide: During the use of the flotation machine, there will be problems that the coal flotation effect is not good or even the flotation is not up, or the phenomenon of the flotation effect is not good. What is going on? Magnesium ore flotation equipment
Some customers have encountered such problems. During the use of the flotation machine, there will be problems that the coal flotation effect is not good or even the flotation is not up, or the phenomenon of the flotation effect is not good. What is going on? What are the factors of the selection effect? Please see below:
1. What happened when the coal did not float up?
Answer: The phenomenon that coal does not float up is often accompanied by gangue not sinking. There are three main reasons for this phenomenon: 1. The feed concentration is large, and there is a lack of clean water; 2. Individual phenomena, such as coal mining weathering zone This phenomenon will occur; 3. Not adjusted well, you can adjust the scraping speed.
2. What are the factors that affect the flotation effect?
Answer: The factors affecting the flotation effect mainly include the following three aspects:
1. It is related to the particle size of the mineral: it has been proved by practice that when the particle size of the mineral is suitable, the effect is good, too coarse or too fine, which is unfavorable to the flotation effect. When the material is too coarse, it will exceed the carrying capacity of the bubbles, resulting in floating. ;
2. Related to the size of bubbles: Generally speaking, the smaller the bubble, the better, which will increase the contact area of minerals. However, if the bubble is too small, it will cause the floating speed to decrease, so the size of the bubble should also be controlled Within the proper range;
3. It is related to the surface of minerals: the uniformity of the mineral surface, the degree of oxidation of the mineral surface, will directly use the effect of the drug, the better the effect of the drug, the better the flotation effect. The good surface can be more Good absorption of chemicals, increase the flotation effect.
