Average wind speed is about 6.5 m/s, giving an average power output of 900W (from power curve). Average energy per day is 900W x 24h = 21,600 Wh or 21.6 kWh. Obviously the relative energy outputs are very dependent on location. If we take Atlanta, Georgia as another example, average wind speed is only 5.5 m/s, giving a power output of about 500W.

Get MoreSemi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These
