The crushed coal (coming from primary crusher) is stored in the cylindrical shape thing known as Bunker which is exactly on top of the mill to introduce coal into the pulveriser also known as coal mill. The grinding table i.e bowl is rotating as the roller is maintained at position using spring such as the distance between bowl and rollers is 1mm.
To expose the coal layer, the layers above it need to be removed. The vegetation and soil, called the topsoil, is removed and kept aside so that it can be re-deposited in the area after mining. If there is a layer of rock above the coal face, called the overburden, this is also removed before the coal can be excavated.
