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 fireexplosion hazard risk.Coal is often the main fuel source used to heat the cement kiln.
