In the cement manufacturing process, most material must be broken, such as limestone, iron ore, clay and coal etc. Limestone is the main raw material for cement production, each producing a ton of clinker needs about tons of limestone, more than 80% of raw material is limestone.
Portland cement Manufacturing process. Portland cement is made by heating raw materials rich in oxides of silicon, calcium, aluminium and iron to temperatures of around 1200 – 1400oC. The chemical reactions that occur within the partially molten mass result from the formation of the four main cement .
The clinker manufacturing process starts with the extraction of the raw meal from the homogenization silo to insure that the raw meal is stable and homogenized in order to produce consistent clinker quality. The preheating of the material takes place in preheater cyclones fitted with a precalciner fired with petroleum, natural gas or coal.
