<p>The invention provides a manufacture method of cement clinker with desulfurization slag as raw material, wherein the consumption amount of limestone can be reduced, and cement clinker can be obtained by low-temperature calcination. Limestone, clay, silica and iron can be applied as raw materials. The method is characterized in that the desulfurization slag can be used as part of raw material, the consumption per unit of desulfurization slag is 30 to 400 kg/t. Perferably, in the desulfurization slag, calcium content calculated by CaO is more than 40 weight%, sulphur content is from 0.5 to 10 weitht%, and fluorin content is from 0.03 to 2.0 weight%.</p> |
