It is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter, i.e.,P M = Mill Constant * (Mill Diameter ) n where n = 0.3 to 0.5. It is evident that mill power is a function of the height at which the media is lifted and the density of the media, i.e., PM = K Ï b LD 2.5 where k is a proportionality constant.

PUMP DESIGN Figure 4 Working principle of a differential (double-acting) piston pump (a) and geometry of the Colombian Gaviotas pump (b). As water is lifted only during the upward stroke, the torque (and power) requirement of a single-acting piston pump varies cyclically. During the upward stroke the piston is subject to the full water pressure.
