氧化铝生产过程中晶种分解及粒度量化控制方法OA

Given the current difficulty in precisely controlling particle size distribution during the decomposition of alumina seed crystals,this study systematically analyzes the formation mechanisms and influencing factors,elucidating the synergistic effects of temperature gradients,stirring intensity,and additive addition on particle size evolution.It introduces the principles and applicable scenarios of quantitative measurement methods such as laser diffraction and electron microscopy,and establishes a decomposition control method centered on particle size feedback.Based on a case study of system 改 造,the research findings indicate that this control system can significantly enhance D50 stability,narrow the particle size distribution range,and simultaneously improve precipitation efficiency.
