Clinker

Cement Clinker:
Cement clinker is a solid material produced in the manufacturing process of Portland cement as an intermediary product.
Clinker occurs as lumps or nodules, usually 3 mm to 25 mm in diameter. It is produced by fusing together without melting to the point of liquefaction limestone and clay during the cement kiln stage.

Applications:
Portland cement clinker is ground to a fine powder and used as the binder in many cement products. A little gypsum is sometimes added. It may also be combined with other active ingredients or chemical admixtures to produce other types of cement including:

•ground granulated blast furnace slag cement
• pozzolana cement
• silica fume cement

Clinker, if stored in dry conditions, can be kept for several months without appreciable loss of quality. Because of this, and because it can easily be handled by ordinary mineral handling equipment, clinker is traded internationally in large quantities. Cement manufacturers purchasing clinker usually grind it as an addition to their own clinker at their cement plants. Manufacturers also ship clinker to grinding plants in areas where cement-making raw materials are not available.
