  • 3.4 Burning in a kiln – clinker formation

    The clinkering process is complete when all of silica is in the C3S and C2S crystals and the amount of free lime (CaO) is reduced to a minimal level (<1%). To make this process more efficient, suspension preheaters are used in modern cement plants to replace the cooler upper end of the rotary kiln (see Figure 32).

    By 1905, the largest kilns were 2.7 x 60 m in size, and made 190 tonnes per day. At that date, after only 15 years of development, rotary kilns accounted for half of world production. Since then, the capacity of kilns has increased steadily, and the largest kilns today produce around 10,000 tonnes per day. In contrast to static
