Our 2050 Roadmap - The 5C Approach: Clinker - Cembureau

Clinker is produced by heating crushed limestone and a mix of other materials (clay and sand) to 1450 °C in a rotary kiln. Clinker is later ground down to a fine powder and mixed with gypsum and other ingredients to make cement. The rotary kiln is the heart of the manufacturing process where raw materials are heated up and decarbonisation of ...

Cement Kilns: Clinker

Clinker produced by early static kilns was in the form of large pumice-like lumps. Rotary kiln clinker on the other hand, because of the rolling action of the kiln, emerges as fairly regular roughly spherical hard nodules of diameter typically 5-50 mm, together with a certain amount of dust abraded from the nodule surfaces.. Clinker minerals react with water to produce the hydrates that are ...
