The power requirement of cement plants varies in accordance with the heat treatment process used viz., dry process or wet process. While the wet process requires almost 1,300-1,600 kcal/kg of clinker and 110-115 kwh of power to manufacture 1 tonne of cement, the dry process requires 720-990 kcal/kg of clinker and 95-110 kwh of power.
The high cost of thermal energy and the consumption of almost three times the net theoretical heat that is required in clinkering process continues to be a nagging problem faced by VSK cement plants.

The production of cement contributes to the emission of CO 2 through the combustion of fossil fuels, as well as through the decarbonisation of limestone, and roughly represents about 5% of anthropogenic global CO 2 emissions [1], [2]. The energy costs are a significant part of the total production costs, typically 20–40% of operational costs [1].
The production cost of this method is relatively low and the production process is simple. How to manufacture oil well cement? The production process of oil well cement is basically the same as ordinary Portland cement. It can be roughly divided into five steps: raw material crushing, raw material grinding, clinker calcination, cement grinding ...
