Coal Grinding - Cement Plant Optimization

Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...

Pulverizer Vibration Issues

This "rumble" in almost all cases is caused by very high fineness. There are two recommended courses of action to alleviate the "rumble". The first, and preferable, is simply to raise the minimum load point at which the pulverizer is removed from "service". Higher coal flows will result in lower fineness.
