Chemical process industries are running under severe constraints, and it is essential to maintain the endproduct quality under disturbances. Maintaining the product quality in the cement grinding process in the presence of clinker heterogeneity is a challenging task. The model predictive controller (MPC) poses a viable solution to handle the variability. This paper addresses the design of ...

Discrete Element Methods (DEM) is a numerical tool consolidated to the simulations of collisions in particulate systems. In this paper, the method was used to study the collisions between grinding media and grinding media and walls in ball mills, which is the most used unit operation in clinker grinding, the majority component of the cement. Amongst the variables that affect the dynamics of ...

Cement Grinding: cement grinding is the final stage in Portland cement manufacturing. In this step, clinker will be ground in grinding mill to reach the qualified fineness of cement product. During the grinding, we usually add gypsum, fly ash and other raw materials into the cement to realize the different usage of cement.

As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...
