  • Cement Production - The Concrete Portal

    Typical rotary kilns (example in Figure 4) are more than 40 m long. The inside of the kiln is lined with refractory bricks. Temperature increases along the length of the kiln from 850 – 950 o C at the inlet to 1450 – 1500 o C at the outlet. The choice of the refractory linings will thus depend on the temperature properties of the materials used and their cost.
