Ordinary Portland Cement Clinker is the core component in producing cement which is formed by sintering limestone. In the manufacturing of Portland cement, clinker formed by sintering or fusing together without melting to the point of liquefaction, alumina-silicate materials such as clay and limestone during the cement kiln stage and happens as 3 millimeters (0.12 in) to 25 millimeters (0.98 in) in diameter,
Ordinary Portland Cement Clinker is then ground to a fine powder and used as the binder in many Cementous goods. Sometimes, a little gypsum is also added. If stored in dry conditions, Cement Clinker can be kept for several months without considerable loss of quality. Because of this fact, and because it can be easily handled by ordinary mineral handling apparatus, Cement Clinker is highly traded intercontinentally in large quantities. At their cement plants, cement manufacturers which purchase clinker usually grind it as an addition to their own clinker. Producers also tend to ship their clinker to grinding plants in zones where cement-making raw materials are not available.
Arij Global Trading LLC, one of the independent traders of different types of clinker, gray and white in the area, supplies tons and tons of clinker annually. Arijâ??s special performance has led us to strong partnerships with global cement manufacturers as well as end-users. The Arij Global Trading has aggressively expanded its sources for clinker as well as other related merchandises to offer the most competitive rates under both CFR and FOB terms.
