Research Progress on Fineness Control of Cement Grinding
Aiming at the problem of too fine cement particles and narrow particle size distribution in the cement final grinding of roller press,the numerical simulation process of roller press grinding was analyzed and the optimal particle size distribution of cement grinding was investigated.The domestic and international research results on fineness modeling of cement grinding,process optimization and grinding fineness control were summarized,and establishing a fuzzy cogni-tive map model was thought to solve the problem of uneven size distribution of cement particles.The improved proportion integral derivative control strategies,advanced control methods such as expert systems,neural networks,fuzzy control and model-referenced adaptive control algorithm based on optimal theory were explained and the feasibility of above methods apply to the cement final grinding process of roller press was demonstrated.It is pointed out that the control strategy combining fuzzy cognitive map and model reference adaptive control can optimize particle size distribution of cement and improve quality of cement products.
