Date Dec. 11, 1997The present invention concerns a process for the production of cement clinker in rotary kilns with substitution of primary raw materials and fuels by use of residual materials containing minerals and combustible parts with moisture contents of up to about 65% without predrying. The process makes possible a material and/or thermal utilisation of residual materials in the case of saving of the clay and fuel sources and relief of dumping with simultaneous lowering of the emissions, above all NOx, in the cement rotary kiln.</p> |
