The Wide Use and Running Course of Flotation Machine
After comparing the flotation results of chromites by the flotation column and traditional flotation cell, we can see that the separating effect of the flotation column is better. After researched by technicians, the flotation column has been used in the flotation of coal powders. And in the future it will have wider application in processing rocks and ores to be deslimed and concentrated after being fine ground.
The industrial flotation equipment in the mining mechanical market has made great development achievements in recent years, and the improvement of the flotation machine technology significantly enhances the output and production efficiency of the ore beneficiation plant.
Working Steps of SF Flotation Machine:
1) After intensively mixed, the pulp and medicaments are fed to the groove bottom of the first tank.
2) The impeller of the flotation machine begins to rotate; negative pressure is formed, which makes the air and pulp at the bottom and middle part of the tank enter the mixing zone. The pulp, air and medicament are then mixed in the mixing zone.
3) As a result of the centrifugal force, the blended pulps are led to the mineralization area. The air is in full contact with the coal particle and forms mineralized bubbles which are then equally distributed to groove wall and removed upward to the separation region. These bubbles then gather as a foam layer and are discharged by the scraping tool. Finally, clean coal foam is produced by this flotation machine.
The flotation method of the flotation column which is one of the flotation machines originated from Canada and it is originally used in the concentration of molybdenum concentrate. In 1980, a double-column flotation unit was installed in the molybdenum return circuit in the mine of Gaspe, Canada and achieved good ore dressing effects. This flotation column unit replaced the mechanical flotation machine of the concentrate series. From then on, many countries in North America installed the flotation column in the copper and molybdenum production plants to concentrate molybdenum minerals and the flotation column began to spread to other countries in the world and was used for coarse and sweep separating various ores and rocks. The flotation column has been the topic of the international conference for twice in three years.
