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.

Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.

Continuous blending involves simultaneous feeding of the silo, overflow to a second silo and final discharge to kiln feed. Modern equipment generally uses continuous CF silos, each having capacity of more than 24-hours' kiln feed and yielding a blending ratio (or 'blending factor') of 4-8, or around 2-3 for older silos.
