Extraction and Preparation of Raw Materials. The main raw materials (limestone, clay chalk or basalt) are quarried from natural rocks. They are crushed and transferred to pre-blending storage where other substances (such as sand, iron ore, bauxite, shale, slag, fly ash) are added to get the desired chemical composition.
Energy considerations are equally important: having mills with a capacity greater than that of clinker production, grinding can be done during periods that offer the most favorable energy rates. The power supply and charges vary from plant to plant and also the arrangements for programming the grinding.

Clinker, made from magnesia-rich feed must be very rapidly cooled once it has been burned, to guard against production of unsound clinker. Plants faced with this problem usually locate the burning zone very close to the discharge end of the kiln and have quick quench compartments at the inlet to the cooler.
