Coal Mill an overview | ScienceDirect Topics

To summarize the coal mill controls, The raw (coal) feed enters the mill through a central delivery pipe and falls under gravity onto the Grinding Table; In many applications, there is an elbow, scroll or turning head in the coal pipe at the burner inlet. Such inlet devices result in ‘roping’, or an uneven distribution of coal
