| 中文摘要: |
| 埃塞俄比亚地质形成期较短，且具高原国家构造活动复杂的特质，埃塞俄比亚的水泥厂所使用的原料、燃料、混合材料等具有其特定的资源禀赋特征。其中，砂岩的成熟度较高，对于生料粉磨和烧成均具有一定的影响；黏土中铁质含量高，一般不需要加入铁质校正原料；混合材主要为天然物料-浮石、火山灰、凝灰岩、石灰石等；当地的燃料以褐煤为主，其热力性能难以单独作为水泥烧成燃料使用，还需要进口高热值燃料混合使用。 |
| 英文摘要: |
| Ethiopia has a short geological formation period and has the characteristics of complex tectonic activities in plateau countries. The raw materials, fuels and mixed materials used in Ethiopia's cement plants have their specific resource endowment characteristics. Among them, the maturity of sandstone is high, which has a certain impact on raw meal grinding and firing; The iron content in clay is high, so it is generally unnecessary to add iron correction raw materials; The mixed materials are mainly natural materials - pumice, volcanic ash, tuff, limestone, etc; The local fuel is mainly lignite, and its thermal performance is difficult to be used as cement burning fuel alone. It also needs to be mixed with imported high calorific value fuel. |
