Black flotation machine is suitable for non-ferrous metal sorting, but also for non-metallic such as: coal, fluorite, talc sorting. The flotation machine drives the impeller to rotate by the electric motor V-belt drive, and generates centrifugal force to form a negative pressure. On the one hand, the air is mixed with the slurry, and on the one hand, the slurry is mixed with the medicine, and the foam is refined to make the mineral bond foam. , floating to the pulp surface to form mineralized foam. Adjust the height of the shutter and control the liquid level so that the useful foam is scraped off by the scraper. The following Zhongnuo machines introduce you to the eight secrets of flotation machine maintenance:

1. The working capacity and working period of the flotation machine are determined by the maintenance and maintenance of the normal work of all the main parts. All the working parts should be carefully inspected for 3 to 4 months, and the new flotation machine Frequent inspections during the first few months of work;

2. Only qualified personnel can check the flotation machine.

3. In order to replace the vulnerable parts in time to shorten the downtime of the flotation machine, a full set of wearing parts must be kept in the warehouse. The date of use and the amount of reserves of consumables are determined on a case-by-case basis.

4. It is necessary to ensure that the operator of the flotation machine has certain technical guidance or training, and strives to be fully familiar with the machine.

5. In order to prevent dirt and useless substances from being mixed into the oil, there should be a filter when filling the oil. When the flotation machine is working, the oil cover should be sealed.

6. After checking before driving, and contacting the upper and lower processes, the flotation machine can be started.

7. The order of driving the flotation machine is: press the upper gate switch and press the start button.

8. After driving, it is strictly forbidden to touch the rotating part of the flotation machine by hand.
