The various types of grinding systems currently being used for cement grinding in a cement plant are: • Conventional tube mill - Open and Close circuit • Tube mill with precrushing unit i.e. vertical shaft impactor (VSI) or horizontal impact crusher (HIC) • Roller press in semi finish and finish grinding mode
A great many open and closed loop controls can be found in the cement production, however, the proper control of the operations-triplet proportioning-burning-grinding can ensure to reach the overall control aim, the other controls are auxiliary ones. Therefore these three areas will be investigated next.

Finally comparison is made between different control algorithms for improving the accuracy of control provided in cement grinding mill. Key words: Cement Grinding Mill; Intelligent Control; PID
A first principles model of a cement grinding circuit is developed for the purpose of multi-variable model predictive control (MPC). The model is based on a series of mixed flow reactors with an ideal screen to model flow between the two chambers in the ball mill. The separator is modelled by efficiency curves.

control system, which makes water injection in the mill irrelevent, ensuring the optimal thermal balance of the FCB Horomill grinding plant. This has a significant impact when considering stand-alone cement grinding installations, as the hot gas generator is the only heat source and the corresponding fuel consumption is a critical operational ...
Logical Dynamic (MLD) systems but at Jura Cement, this was applied for the first time to a cement mill. MLD systems had been applied elsewhere in the cement industry, to control kilns and raw mix for example, but this was the first known application of this technology on a cement mill. MLD systems were recently developed
