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.

Using this strategy, a reduction in the use of higher cost additives later in the process may be realized as well as a reduction in material variability at the raw mill. However, many times the most benefit can be achieved through the application of the instrument at the raw mix proportioning stage within the process.
