Describes the characteristics of the solid phase reaction Rotary kiln

Article source:

Rotary kiln solid state reaction process needs to be further improved, from features to see the entire roasting process, we need to know more about more features present in the reaction process. Summarizes the characteristics of the following aspects: 1.Another feature of the solid phase reaction is exothermic, it emits heat, direct all used to raise the temperature of the material, so that the material inside the Rotary kiln temperature quickly rises to the sintering temperature. 2.When the powder material decomposition reaction is substantially complete, the material temperature gradually increased, further solid phase reaction.General primary solid phase reaction began at 800 ¡æ calciner.However, due to the state in suspension calciner, not close contacts between the components, so a lot of the major solid phase reaction carried out in the temperature rise into the Rotary kiln and make the material until the last generation C2S, C3A and C4AF. 3.Precalciner solid phase reaction compared with preheater Rotary kiln, the task is relatively increased.In order to facilitate faster for a solid-phase reaction, in addition to a large selection of active material, the powder material to maintain or improve the fineness and uniformity is very important.
