Coal mill pulverizer in thermal power plants

Coal is not abrasive by itself The minerals in coal that are the most abrasive are quartz and pyrite, which cause a abrasion or severe wear carbides in the metal part, High chromium cast iron materials are used for improved abrasion resistance Worn Journal RollFIELD OF THE INVENTION This invention relates to the protection of coal mill journals from abrasive wear due to the impingement of coal fines carried by an air stream flowing through the coal mill and more particularly to a method and apparatus for of protecting a coal mill journal comprising the steps of attaching a liner form made up of flat surfaces to the journal and covering the flatMethod and apparatus for protected coal mill journals
