What is the function of the impeller cover of the flotation machine? We all know that the impeller not only refers to the disc equipped with moving blades, which is an integral part of the rotor of the excited steam turbine, but also refers to the general term of the disc and the rolling blades on it. What is the use of adding an impeller cover?
1. When the pulp is thrown out by the impeller, a negative pressure suction is formed under the cover plate;
2. Scheduling the amount of pulp entering the impeller;
3. It can prevent the ore from pressing the impeller and making it difficult to start when the machine is shut down;
4. To play a role in stabilizing the flow. When the flotation machine is in operation, the ore feeding pipe feeds the ore slurry to the center of the cover plate, and the centrifugal force generated by the impeller rotation will throw the ore pulp out, forming a negative pressure between the impeller and the cover plate at the same time. Therefore, outside air is automatically sucked in through the intake pipe. The vigorous agitation of the impeller makes the pulp and air fully mixed, and divides the airflow into many fine air bubbles. Furthermore, some air bubbles will also be separated from the slurry behind the impeller blades.
