Cement
A sector with simultaneous thermal and electrical intensity, driven by the clinker kiln and ball mills.
In cement manufacturing, energy is consumed both thermally in the clinker kiln and electrically in raw meal and cement grinding, and the two must be tracked separately. The kiln carries the largest share of energy cost and is sensitive to raw meal moisture, combustion air temperature and fuel quality. Ball and vertical roller mills also carry high electrical intensity that depends directly on target fineness and material hardness. Alternative fuels cut fuel cost but make kiln stability harder to hold.
Energy management challenges in cement
High specific thermal energy consumption in the clinker kiln, sensitive to raw meal moisture
High electrical intensity of ball mills to reach the specified fineness
Variable quality and share of alternative fuels affecting kiln stability
Heat losses from the kiln shell and preheater due to worn refractory
Coordinating mill start/stop with time-of-use electricity tariffs to reduce demand cost
Air leakage in the preheater tower reducing kiln thermal efficiency
Gita 50001 for cement
Clinker thermal energy baseline
Modeling kiln specific thermal consumption against clinker tonnage, raw meal moisture and alternative fuel share to isolate genuine deviation from normal performance.
Cement mill schedule optimization
Recommending ball mill run schedules aligned with time-of-use electricity tariffs to cut energy cost without reducing daily production capacity.
Alternative fuel share tracking
Logging and analyzing the share and calorific value of alternative fuels fired in the kiln to ensure combustion stability and accurate energy input reporting.

In plants with an active fuel substitution program
A two-kiln cement plant, after implementing a clinker thermal baseline and preheater temperature monitoring, identified efficiency losses caused by air leakage and corrected them during scheduled maintenance, reducing specific fuel consumption and improving kiln thermal stability across comparable operating periods.
