Mill Feed Sep. Return Final Product System Fan Figure 1: Closed circuit grinding system. milling system is a delicate task due to the multivariable character of the process, the elevated degree of load disturbances, the different cement types ground in the same mill, as well as the incomplete or missing information about some key process charac
The cement mill grinding circuit resembles to some extent grinding circuits used in the mineral industry. Model based control technologies for such grinding circuits in the mineral processing industries have been surveyed by Pomerleau et al. (2000), Hodouin et al. (2001), and Wei and Craig (2009). Raja

Closedcircuit ball mills have been operated for cement milling for decades [[7], [8], [9]].Fig. 1 shows the process flow of a closedcircuit, twocompartment cement ball mill. The closedcircuit operation helped to reduce overmilling of particles [10], resulting in lower specific power consumption [11] in comparison with opencircuit operation, where the ball mill is operated without the ...
Energy optimization of a circuit has been subject of many of the studies. Jankovic et al. [12] considered the optimization alternatives of cement grinding circuits. Benzer [13] studied on optimizing the fully airswept raw mill grinding circuit, Dundar et al. [14] reported the optimization opportunities of a cement grinding circuit.

The opencircuit grinding system of the ball mill is shown as follows: materials (including clinker, gypsum, mixed materials, etc.) mixed according to a certain proportion will be directly stored in the steel silo as finished cement products after being ground by the ball mill.

Mill power draw prediction can be carried out using Morrell's power model for tumbling mills. The case study. Potential benefits of using the crusher for clinker precrushing were studied for a cement plant. Fig. 2 shows the proposed cement grinding circuit. Bseries VSI (vertical shaft impactor) crushers are applied to a broad ...
Our results suggest that integrating an air classifier into an opencircuit ball mill can increase the production rate by 15% or increase the cementspecific surface area by 13%. A singlecompartment mill entails a premilled feed for proper operation, whereas a twocompartment mill yields a finer cement product than a threecompartment mill.
Step 4:Cement grinding and storage. Clinker and gypsum for Ordinary Portland Cement (OPC) limestone for limestone cement, and slag for slag cement are all extracted from their respective hoppers and fed to the cement mills. The ball mill grinds the feed to a fine powder in two chambers, namely the first and second chambers.
