Advanced process control for the cement industry

2019-8-26  Vertical roller mill application Control challenges Among the operational challenges of a vertical roller mill are the fast dynamics of the process. Compared to ball mills with dynamics changing in 15-20 minutes, vertical roller mills have dynamics changing in 2-4 minutes. The fast dynamics necessitate even closer attention to,LOI.
