One of the key subsystems in thermal power plants is the coal mill used to pulverize the coal before it gets into the plant furnace. The interior of the mill rotates and the plates located on the inside grind the coal into a small size powder. During that process the plates within the mill slowly get depleted and the productivity of the mill ...
