The widely used GE 1.5-megawatt model, for example, consists of 116-ft blades atop a 212-ft tower for a total height of 328 feet. The blades sweep a vertical airspace of just under an acre. The 1.8-megawatt Vestas V90 from Denmark has 148-ft blades (sweeping more than 1.5 acres) on a 262-ft tower, totaling 410 feet.
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 b LD 2.5 where k is a proportionality constant.
