How ball mills work. A ball mill grinds material by rotating a cylinder filled with media (typically metallic or ceramic balls) mixed with a continuous flow of feed and recycled material. At slower rotational speeds, the grinding media creates a cascade motion where the media is mainly rolling and shear forces for grinding are generated.

The vibration can be generated by springs, electromagnets, air cushions or unbalanced mass. These mills also have application in fine (45 microns) grinding. High-energy vibration mills can grind materials to surface areas of around 500m2/g, a degree of fineness, which is impossible in a conventional mill (Russell, 1989).

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 both lift and drag.
