The clinker production stage is where the raw material (the raw meal) converts into clinker. The raw meal is fed into a rotary kiln through a preheater at about 1450 °C to produce clinker, the primary cement component (GHG, 2008; Salas et al., 2016 ). The kiln is known as the heart of the cement production process.
