Manufacturing Of Cement By Dry And Wet Process

08-09-2018  Burning and Grinding: These operations are the same as for the wet process. Except for the mixing of raw materials. In the dry process, the raw materials mixed, fined, and then fed into kiln whereas, in the wet process, the raw materials are crushed separately and then directly mixed in correct proportion in the presence of water to make a fine thin paste known as Slurry.

Cement - NETZSCH Grinding Dispersing

Cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cements used in construction are usually inorganic, often lime or calcium silicate based, and can be characterized as either hydraulic or non-hydraulic, depending on the ability of the cement to set in the presence of water.
