Fire and Explosion Hazards in Cement Manufacturing …

Coal is often the main fuel source used to heat the cement kiln. Coal pulverizers are required to grind the coal from the bulk storage size to a smaller particle diameter to use in the kiln. Coal pulverizers significantly reduce the mean particle size of the coal, drastically increasing the fire/explosion hazard risk. This risk is present inside the pulverizing equipment and during transport to the kiln for burning.

COAL HANDLING SAFETY - AMETEK Land

coal and the high temperature inside the mill lead to rapid oxidation of the coal. This results in further heat build-up and the potential for a fire. If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the in-rushing combustion air.

Coal Grinding - Cement Plant Optimization

Single chamber ball mills (with classifying liners and dam ring) with drying chamber and static or dynamic separator are commonly existing for coal grinding in cement plant for one or more kilns as per capacity. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Grinding media consists ...
