Dry Process Of Cement Manufacturing\Dry Process Of Cement

CEMENT MANUFACTURING PROCESS AND ITS SELECTION

This process was especially evolved to counter the main drawback of the wet process i.e. high fuel consumption. In this process, the raw materials ground in dry condition are homogenized and then nodulised in a pan noduliser of dish or rotary type by adding controlled quantity of water (10- 12 %).

Difference Between Wet And Dry Process Of Cement. Dry process. 1- Mixing of raw material in a dry state in blenders. 2- The dry materials exiting the mill are called “kiln feed”. 3- Size of the kiln needed for the manufacturing of cement is smaller. 4- Difficult to control mixing of Raw materials, so it is difficult to obtain a better homogeneous material.
