A mechanical classifier often receives its feed from a ball mill and produces (1) finished material which overflows to the next operation and (2) sand which returns to the mill for further size-reduction. The term "circulating load" is defined as the tonnage of sand that returns to the ball mill, and the "circulating load ratio" is the ...
Apparent power, also known as demand, is the measure of the amount of power used to run machinery and equipment during a certain period. It is found by multiplying (kVA = V x A). The result is expressed as kVA units. PF expresses the ratio of true power used in a circuit to the apparent power delivered to the circuit. A 96% power factor ...
Genomic studies in African populations provide unique opportunities to understand disease etiology, human diversity, and population history.

The shaft seal is a sealing element which seals the rotating shaft of a centrifugal pump where it passes through the non-rotating pump casing, reducing fluidleakage to atmosphere or the entry of air from outside to a certain level, and keeps wear of the sealing faces as low as possible.. Pumps are specially designed and manufactured to cater for a whole range of different applications.

Ball mill is a high-energy mill process especially used for anenergy-intensiveprocess likemechanicalalloying,mecha-nochemistry, or mechanical activation. Planetary ball mill is used to determine the dependence of process efficiency using milling parameters such as ball size and number, mill geom-etry, and velocity of the rotating parts.
