Cement is a crucial building material used in construction. The Cement manufacturing process involves the extraction and preparation of raw materials, such as Limestone, clay, shale, iron ore, and Gypsum. These materials are crushed, ground, and blended to form a raw meal, which is then heated in a kiln at high temperatures.
