Difference between dry process and wet process of cement production.

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
