Coal mills are used in coal fired power plants to grind crushed coal lumps with several cm diameters to very fine powder in the order of 50– 100 μ m diameter. A further task of coal mills is to dry the coal particles avoiding wet coal conditions during combustion. This is achieved by hot air passing through the mill which evaporates the …

coal and the high temperature inside the mill lead to rapid oxidation of the coal. This results in further heat build-up and the potential for a fire. If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the in-rushing combustion air.
