Thermal power plants use different types of coal pulverizers. The method used is attrition, impact, or a combination of both. This article explains the characteristics of the three main types attrition, impact and attrition, and impact or hammer. Selection of the type of pulverizer depends on the grindability of the coal, the capital costs and maintenance costs, and considerations for licensing.
Coal is a combustible, sedimentary rock that, as a fossil fuel, is more abundant than either oil or gas. There are several varieties of coal, but the most abundant is Bitumus coal, which is used for power production and to make coke for steel production. Coal burning accounts for approximately 44% of the world''s carbon emissions.
