Difference between dry process and wet process of cement production.



Dry process
Wet process
Raw materials are mixed in its dry state
Raw materials are mixed in wash mill along with 30-50% of water
Dry mixed raw materials entering to the kiln are called as kiln feed
Wet mixed raw materials entering to the kiln is called as slurry
Size of kiln required in this process is less
Size of kiln required in this process is more
Since the mix is in dry state, therefore achievement of homogeneity of the mix is of lesser degree
Raw materials are mixed in wet state , degree of homogeneity of the mix achieved is high
Fuel consumption for this process is less
Fuel consumption for this process is more
Energy required is less
Energy required is more
Cost of production is less
Cost of production is more
Carbon di oxide emission is comparitively less in this process
Carbon di oxide emission is comparitively more in this process
