Steel ball coal mill


Steel ball coal mill, as the important auxiliary equipment of pulverized coal boilers,is a kind of machinery that grinds coal into pulverized coal.The coal grinding process is a process to crush coal and increase its superficial area continuously. To create new superficial area, the bond of molecules of solid must be broken, so this process needs to consume energy. There are three main ways to grind coal into powders: crushing, shattering and pulverizing. Among the three ways, crushing is the most energy-economical one, and pulverizing is the one consuming the most energy. Coal mill, nowadays, usually adopt two or all the three ways mentioned above when grinding coal, but it needs to depend on the type of coal mill to tell which way is the main one applied to the mill.
