What factors can cause the flotation machine to not work normally?

 The flotation machine is a full-grain flotation machine, suitable for both coarse and fine particle separation. After the Chinese pulp of the GLF flotation machine is processed, the flotation machine must be agitated and aerated, so that the mineral particles can be fixed on the bubble and float to the surface to form a foam product, and the rest will be stored in the pulp for separation . The GLF flotation machine is not only a stirring device, but also capable of forcibly blowing in air under the external special action. The mechanical stirring device is used to agitate the slurry to distribute the air flow, and the aeration and stirring of the slurry work separately. The GLF type aerated stirring flotation machine can be adjusted according to its own needs at best. Only in this way can it be helpful to improve the sorting capacity and processing capacity of the flotation machine. However, due to the larger processing capacity and the shallower flotation cell, the required power consumption is lower. GLF flotation opportunities because the impeller speed is low, the concentration of the slurry when passing through the impeller will also be lower, and the ore particles will become finer, which will correspondingly reduce the efficiency of flotation. In this case, the impeller and stator will reduce wear. There is a grid plate in the flotation tank, which will cause a suspended layer of coarse particles, which can make the surface of the slurry more stable and make the technical performance better. In this case, it is beneficial to the coarse particle flotation.

There are several common faults of GLF:

(1) The cover plate or stator screw of the flotation machine is off.

During the entire operation of the flotation machine, the cover plate and screws will easily fall off due to the rotating impact and vibration of the flotation machine itself. This situation will affect the normal operation of the flotation machine. Therefore, the flotation machine is carefully checked before each work.

(2) The bottom of the flotation machine is worn.

If the flotation machine runs for a long time and rotates strongly, the bottom of the tank will be worn and thinned, and the surrounding guard plate will be worn and deformed, and under the action of the flotation agent, the bottom of the tank will also be worn and deformed. Therefore, when wear occurs, It is necessary to repair welding in time.

(3) Pry up the bottom guard plate of the groove.

During the flotation process, the tank bottom guard plate protects the bottom of the tank. When the impeller rotates strongly, the circulation of the ore in the flotation tank will be accelerated. In severe cases, the charge will increase and the guard plate will be pryed. It will cause an accident.

(4) Wear and corrosion of impeller and cover plate.

The impeller and cover plate are the core components of the flotation machine, and it is also a position that is easy to wear. It is directly related to the degree of aeration of the slurry during the flotation process. The degree of agitation in the sea area, but because the flotation machine is in the process of long-term work, it will The impeller also damages the cover plate, so the impeller and cover plate need to be repaired and replaced for a long time.

(5) The spindle is worn out.

When the spindle is in use, the rubber sheath of the spindle should be protected. After the rubber sheath is worn, the spindle wears quickly under the action of the internal circulation of the slurry, and it is very easy to break the shaft. Therefore, it should be updated frequently during the inspection. Rubber sheath.

(6) The bearing clearance becomes larger.

When the main shaft of the flotation machine is running at high speed, the bearing gap will easily become larger, which will damage the bearing. At this time, only the tightness of the inner and outer gaskets of the bearing needs to be adjusted.

(7) The motor generates heat.

During the operation of the flotation machine, too much sand accumulates in the flotation cell, the cover plate and the ore tube fall off, and the circulation of the ore tube is too large, which will cause the electric heater to heat up. In this case, the cover plate and the ore tube should be provided. Tighten it in time when it is loose, and replace it in time when the circulation volume of the ore pipe is too large.

    As mentioned above, during the use of the GLF flotation machine, due to the harsh environment and poor maintenance during use, various problems will occur. Therefore, timely attention and regular maintenance should be carried out to prevent the work process from being blocked. Off.
