area classification coal grinding

  • PulverizerWikipedia

    The air mixes with and dries coal in the grinding zone and carries pulverized coal particles upward into a classifier. Fine pulverized coal exits the outlet section through multiple discharge coal pipes leading to the burners while oversized coal particles are rejected and returned to the grinding zone for further grinding.

  • Fire and Explosion Hazards in Cement Manufacturing Industries

    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.
