The particle size of rutile concentrate in China is too fine to meet the requirement of chlorination process. It needs to be granulated into micelle with the diameter about 100μm before chlorination. The fluidized bed granulation method was used to prepare micelle, and the influence factors on granulation were studied. The results show that the relative high concentration and the increase of spray...
This study considered the effects of a granular fuel distribution state on the NOx emissions during the sintering process. The results show that fuel pre-granulation technology can be applied to wrapping fuel inside granules to form a double-layered granular structure. Because the in-diffusion of O2 is restricted in granules, the fuel inside the granules is burnt in a relatively low O2 atmosphere,...
