The different meaning of Cement Clinker and Clinker?
Clinker is ground (usually with the addition of a little calcium sulfate) to become Portland cement. It may also to be interground with other active ingredients to produce: blastfurnace slag cement pozzolanic 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. The freight cost is much lower than that for the equivalent amount of finished cement. Cement manufacturers purchasing clinker 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. Happy Holidays !
