How A Wind Turbine Works - Text Version | Department Of
How a wind turbine works. a wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. when wind flows across the blade, the air pressure on one side of the blade decreases. the difference in air pressure across the two sides of the blade creates .
the grinding media is the balls which may be made of steel (chrome steel), stainless steel or rubber. the inner surface of the cylindrical shell is usually lined with an abrasion-resistant material such as manganese steel or rubber. less wear takes place in the rubber lined mills. the length of the mill is approximately equal to its diameter. 7.
