The coal mill grinding system is an important part of the dry process cement manufacturing. In cement plants, we usually adopt the air swept coal mill system or vertical mill system as the pulverized coal preparation system, which is arranged at the cement kiln head or kiln tail to provide fuel for clinker calcination. However, due to the flammable and explosive characteristics of pulverized ...

Draft Fans Forced draft fans (FD) supply the air necessary for fuel combustion by pushing the air through the combustion air supply system and into the furnace. These fans are typically the most efficient fans in the power plant because they have the cleanest operating environment . Typically, these fans are centrifugal fans utilizing radial airfoil blading or variable pitch axial fans.

Summary of Coal Mill Controls. To summarize the coal mill controls, they may be divided basically into two major categories: 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the ...
