Fire and Explosion Hazards in Cement Manufacturing Industries

Feb 18, 2018 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.

Cement Kilns: Size Reduction and Grinding

Coal, as used by the cement industry, rarely needs crushing. Clinker, as produced by early static kilns, emerged as large lumps, and crushing was always required before grinding could take place. Rotary kilns by contrast produce clinker that is typically below 50 mm and does not need crushing. However, every rotary kiln
