Coal feeder are mostly used in thermal power plants as coal is the main source of fuel for the combustion process. And in order to control the combustion correct amount of coal need to feed into the boiler to keep the process under control. As you see in the diagram feeder lies between the bunker and the crusher or coal mill.
