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.
In the case you intend to realise (buy) a new cement production line, the top deciders will not discuss the coal grinding system in length. In the overall situation it isn't that important. A requirement package, which will, of course, demand a safe system to be realised by the supplier, will be decided upon.
