Based on the current situation and existing problems of intelligent construction in the cement industry's grinding system, combined with the achievements of intelligent grinding research, a new intelligent construction plan of "expert diagnosis+ intelligent control+ intelligent operation" is proposed. Taking the "roller press+ ball mill" joint grinding system as an example, the specific content and precautions for the implementation of the intelligent construction plan of the cement grinding system are introduced in detail. The application effect of the pilot enterprise shows that, the new intelligent construction plan can effectively enhance the intelligent level of the cement grinding system, improve the production economic indicators of the cement grinding system, and improve the stability of product quality.
