tion and 5% of the total industrial energy consumption. The cement manufacturing process is illustrated in Fig. 1. The final step in manufacture of cement consists of grind- ing cement clinker into cement powder. Ball mills are used for grinding the cement clinkers. The cement mill circuit consists of a ball mill and a separator.

Cement Museum - Secil

The new line, which was commissioned in 1938, was designed to function independently of the two other lines (I and II) and is therefore called the "new plant". During their route through the museum, visitors can observe and follow the cement manufacturing stages through the Circuit of Stone, designed to convey the main.

Cement mill - Wikipedia

Efficient closed-circuit systems, because of their tight particle size control, lead to cements with relatively narrow particle size distributions (i.e. for a given mean particle size, they have fewer large and small particles). This is of advantage in that it maximizes the strength-production potential the clinker, because large particles.
