The milling process in cement plants is extremely energy-intensive. there are potential energy savings available through the use of Mill Control System (MCS). The MCS is a software system that draws conclusions about the quality levels of the production plant through a knowledge-based approach using current plant data (defined measured values).
Cement producer Holcim only had 12 days to modernize the control system at its plant in Chekka – during a planned kiln maintenance shutdown period. The task was to replace the control system with a new system using the latest version of CEMAT based on SIMATIC PCS 7 Version 7.
For most portland cement plants, the levels of sulfur in raw materials are low enough that most of the SO 2 generated is removed by the natural scrubbing action of the kiln raw feed. However, in those instances where the sulfur content of raw materials is great due to the presence of pyritic sulfur, uncontrolled SO 2 emissions can be significant.

5. Distribution System Within the Plant. In a cement plant also there is a 'mini grid' receiving power from main electricity grid and also from plant's captive power plant. They have to work simultaneously and hence should be 'synchronized' when working in parallel, i.e., the voltage, frequency and phase must match.
- In many cement systems where all the kiln gas passes through the raw grinding mill where they are used for drying the raw material, mercury is often condensed on the raw material due to the relatively low operating temperatures. The majority of mercury emissions from these types of plants often occurs during a relatively brief period of time ...
Waste heat can be utilized directly in the mill by coupling the raw mill to the kiln- and/or clinker cooler exhaust. For suspension preheater-type kilns, a roller mill utilizes the exit gas from the preheater to dry the material in suspension in the mill. A blending system provides the kiln with a homogeneous raw feed. In the wet process the mill
