process of raw mill in cement plant
Review on vertical roller mill in cement industry & its …
In dry process technology, crushed limestone and raw materials are ground and mixed without addition of water. Dry and semi-wet processes are more energy-efficient. The wet process requires 0.28 tons of coal and 110 kWh to produce one ton of cement, while the dry process requires only 0.18 tons of coal and 100 kWh of energy [4].

Under the dry process, raw materials are kept dry by utilising the heat from the raw mill, resulting in poor homogenisation, which leads to inferior quality of clinker. Here, the moisture content in the slurry is 12 per cent, which requires less heat and therefore, less fuel. So, this process consumes less thermal energy.
