    A coal power station turns the chemical energy in coal into electrical energy that can be used in homes and businesses. How is coal energy generated? First the coal (1) is ground to a fine powder and blown into the boiler (2), where it is burned, converting its chemical energy into heat energy. Grinding the coal into powder increases its surface area, which helps it to burn faster and hotter ...

    Grinding and attrition mixed together means energy is being transmitted into the media, not the liner or machine. Because the action works media-to-media, there is very little media-to-liner grinding (see accompanying table above). Media life tends to be 30%–50% higher than most other grinding technologies, especially versus rotary mills in fine grinding applications.
