Cement system and method for operating a cement system |
| 摘要 |
In the method according to the invention for operating a cement plant, the raw meal is preheated in a preheating zone, the preheated material is precalcined in a calcining zone and the precalcined material is finally sintered in a sintering zone. The cement plant is operated in such a manner that the precalcined material which is supplied to the sintering zone has an SO3 concentration of at least 5.5% by mass and a CaSO4 proportion of at least 75%, preferably 90%, of the total salt content. |

1. Method for operating a cement plant with preheating of raw meal in a preheating zone to form preheated material, precalcining of the preheated material in a calcining zone to form precalcined material and sintering of the precalcined material in a sintering zone to form cement clinker, the method characterised in that the precalcined material is supplied to the sintering zone having a total salt content that is at least 5.5% by mass SO3 and at least 75% by mass CaSO4, and further characterized by having a sulphur volatility in the sintering zone that is at least 60%. |
