Coal is a physical mixture of high carbon value coal and rejects. Coal beneficiation is nothing but the separation of these high carbon value coal from rejects (noncarbonaceous material) in a coal body. Although the theoretical knowledge of coal beneficiation is available aplenty in coal preparation books; it is essential that mineral …

The pressure head difference between the inlet and the outlet, or Total Head produced by the pump, is proportional to the impeller speed and diameter. Therefore, to obtain a higher head, the rotational speed or the impeller diameter can be increased. To learn more about how a centrifugal pump increases a fluid's pressure, see reference 15.
