The soft and fibrous structure of many biomasses makes their pulverisation in traditional coal mills ineffective. At the same time, the coal milling performance also decreases, which may cause unacceptable carbon losses due to incomplete combustion. This method is currently suitable practically only for sawdust and pellets. As pellets are composed of small particles, they are more readily
