After crushing, the raw materials are transported to the plant by conveyor. Before homogenized, the plant stores the material. Too finely ground, the materials are transferred to the raw mill, to produce raw mix. The raw mix is preheated before it goes into the kiln, and by the flame, it can be heated to 2000 °c to produce clinker.
