The flotation machine is suitable for the separation of non-ferrous metals and non-metals such as coal translucent stone and talc.
The flotation machine is driven by the triangle belt of the motor to drive the impeller to rotate, resulting in centrifugal action to form negative pressure. On the one hand, the air is mixed with the slurry by inhaling sufficient air. On the one hand, the slurry is mixed with the medicine, and the foam is refined at the same time, so that the mineral adheres to the foam and floats to the slurry surface to form a mineralized foam. Adjust the height of the gate and control the liquid level, so that the useful foam is scraped out by the scraper.
Structural device of flotation machine: This machine is mainly composed of pulp tank, mixing device, aeration device, discharging mineralized foam device, motor and so on.
1. Slurry trough: It has a slurry inlet and a gate device for adjusting the slurry surface. It mainly consists of a trough body welded with steel plate and a gate welded with steel plate and round steel.
2. Mixing device: It is used for mixing slurry to prevent ore deposit in the tank. It is mainly composed of belt pulley, impeller, vertical shaft and so on. The impeller is made of wear-resistant rubber.
3. Inflatable device: It consists of a tube intake pipe. When the impeller rotates, negative pressure is generated in the impeller chamber, which sucks air through the hollow pump tube and disperses it in the pulp to form a group of bubbles. The pulp with a large number of bubbles is quickly thrown into the stator by the rotating force of the impeller, which further refines the bubbles in the pulp. It also eliminates the rotational movement of pulp flow in the flotation tank, resulting in a large number of vertical upward microbubbles, which provides the necessary conditions for the flotation process.
4, exclude the mineralized bubble device: it is to float on the surface of the bubble scraping, mainly by the motor drive reducer, reducer driven scraper composition.
Working principle
When grinding or after grinding, water and necessary reagents are added to mix the ore slurry into a stirring tank, then air is injected into the slurry to form a large number of bubbles. Some mineral particles which are not easily wetted by water, i.e. hydrophobic mineral particles, attach to bubbles and float with bubbles. On the surface of the pulp, mineralized bubbles are formed. Other mineral particles which are easy to be wetted by water do not adhere to the bubbles, but remain in the pulp, and the mineralized bubbles containing specific minerals are discharged, so as to achieve the purpose of mineral processing.
