clinker formation is the combination of silica with calcium to produce hydraulic compounds. However, the actual transformation of the raw materials into clinker involves a combination of chemical and physical processes as the material passes through the kiln system. The general process of clinker formation is described in Figure 1.

Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding.
