Cement Analysis and Production Information
The cement production process. The cement production process begins with the extraction of limestone and clay from the quarry. The material is then blended, crushed and fed to the kiln. Post-kiln, the clinker is cooled and goes through a final grinding method before it is ready to ship. Portland cement, the most common type of cement, is ...

Material is directly conveyed to the silos (silos are the large storage tanks of cement) from the grinding mills. Further, it is packed to about 20-40 kg bags. Only a small percent of cement is packed in the bags only for those customers whom need is very small. The remaining cement is shipped in bulk quantities by mean of trucks, rails or ships.

Efficient grinding unit selection impacts profitability
Therefore, producing cement with less energy is becoming a key element of profitability: as the grinding process consumes about 60 per cent of the total plant electrical energy demand and about 20 per cent of cement production variable cost. So efficient grinding unit selection impacts profitability of cement manufacturing.
