Coal Mill – Coal Mill In Cement Plant AGICO Cement

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 ...
