摘要： PROBLEM TO BE SOLVED: To provide a production process for cement of high quality in spite of use of the waste containing slightly water-soluble chlorine compounds as a raw material. SOLUTION: The waste containing slightly water-soluble chlorine compound 1 is removed its iron scrap 3 and foreign substance 5 by means of a magnetic separator 2 and a fractionation sieve 4 and then charged into the cement kiln in the cement production plant. The chlorine that is taken into by the waste is vaporized in the kiln, and a part of the kiln exhaustion gas is sucked by the alkali by-pass unit 7 and the sucked kiln exhaustion gas is steeply cooled down in the temperature range of from 400-450 deg.C at which the chlorine compound forms. The chlorine taken in by the waste 1 is recovered as a dust containing water-soluble chlorine compound and removed, whereby the cement 8 of high quality from which chlorine is thoroughly separated is stably produced.
