what is rotary cement kiln

  • Rotary Kiln an overview ScienceDirect

    The rotary kiln type is the typical furnace used in all cement factories Rotary kilns used in the cement industry are much larger in diameter and longer in length than the previously discussed incinerator The manufacture of cement from limestone requires high kiln temperatures (1,400°C) and long residence times, creating an excellent opportunity for hazardous waste destructionThe original rotary cement kilns were called 'wet process' kilns In their basic form they were relatively simple compared with modern developments The raw meal was supplied at ambient temperature in the form of a slurry A wet process kiln may be up to 200m long and 6m in diameter It has to be long because a lot of water has to be evaporated and the process ofThe cement kiln Understanding CementPerhaps one of the most common uses for this technology is the creation of a rotary cement kiln, which grinds limestone, clay, and shale down to small bits of rock and transforms them into a usable cement mixture that is ready to be either packaged or immediately usedDuring this process, the materials are exposed to varying temperatures that will evaporate any waterWhat is a Rotary Kiln?
