A pulverizer or grinder is a mechanical device for the grinding of many different types of materials. For example, a pulverizer puritch is used to pulverize coal for combustion in the steam-generating furnaces of coal power plants
Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.
