The Finish Mill Circuit In A Cement Plant Can Be Optimized By Using An Online PSD Analyzer
The finish mill circuit in a cement plant can be optimized by using an online PSD analyzer. Knowing the real-time PSD from the mill can provide the means to reduce over grinding and the heavy cost of energy it causes. When the fines fraction (%<32um) increases above set limits, costly overgrinding is beginning to impact energy consumption and may also cause curing problems through rapid hydration. Likewise, an increase of the course fraction may cause incomplete hydration and early strength results may suffer. This talk will give an overview and practical examples of how an integrated on-line analysis of PSD at the finish mill can provide real time data to improve process performance and efficiency.
