wet process is used. In the dry process, grinding and blend-ing are done with dry materials. In the wet process, the grinding and blending operations are done with the mate-rials mixed with water in a slurry form. In other respects, the dry and wet processes are very much alike. Fig. 2-4 illustrates important technological developments that can

The dry process uses less fuel in the kiln, is easier to proportion, but is more difficult to achieve uniformity in the blending process. The steps of the dry process consist of grinding, drying, blending, and storage. The steps in the wet process are adding water, grinding, blending, and storage. Clinkering

Raw materials are homogenized by crushing, grinding and blending so that approximately 80% of the raw material pass a No.200 sieve. Mixture is fed into kiln & burned in a dry state This process provides considerable savings in fuel consumption and water usage but the process is dustier compared to wet process that is more efficient than grinding.

The ancient observation that hard materials were easier to grind in a liquid medium led to the use of "wet process" grinding of raw materials in the cement industry, and grinding by this technique was always much more energy-efficient than dry grinding, although the energy required to remove the water from rawmix was always vastly greater than ...

2) Wet Process - Feed materials for the wet raw grinding circuit may involve materials stored relatively dry and, in the case of previously processed clay, in "slip" form at perhaps 60% - 70% moisture content. Emissions from the transfer of dry feed components to the mill are normally controlled by low temperature bag-type collectors.
