| description | The invention discloses a method for granulating carbide slag. The method comprises the following steps: S1, finely grinding carbide slag subjected to high-temperature carbonization reduction and water quenching; s2, adding a binding agent, and preparing the finely ground carbide slag fine powder into carbide slag hollow particles required by boiling chlorination in a rapid stirring granulation manner; s3, drying the granulated hollow carbide slag particles, and removing free water and bound water in the hollow carbide slag particles; according to the method, the process of high-temperature carbonization reduction, water quenching, fine grinding, rapid granulation and drying is adopted, carbonized slag particles with the interval of 60-120 meshes are prepared, and the problems that vertical mill carbonized slag fine powder is wide in particle size distribution, the chlorination operation difficulty is large, the chlorination dust removal load is heavy, and the coarse TiCl4 solid content is high can be effecti |
