Abstract:
The results of studying the effect of the vibration processing time on the size of calcium hydroxide particles are given. The physicochemical processes affecting the size and morphology of calcium hydroxide particles have been studied. A stage-by-stage mechanism of the process of the carbonation of lime, depending on its specific surface, is established. The results show that the optimal period for the vibration treatment of lime to obtain the most active material is 20 min. A longer period of vibration results in the merging of particles into larger agglomerates.

Keywords:
