2000-3-17Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration. This is a complex process that is best understood by first understanding the chemical composition of cement. Manufacture of cement Portland cement is manufactured by crushing, milling and proportioning the following materials
We provide quality and efficient solutions to our global customers
2020-5-29The manufacturing process of cement consist of grinding of these raw materials and mixing them in certain fixed proportions based on the purity and composition of the raw materials. After mixing these raw materials are heated in a kiln at a temperature of about 1300 to 1600 degree celcius.

This paper focuses on modelling and solving the ingredient ratio optimization problem in cement raw material blending process. A general nonlinear time-varying G-NLTV model is established for cement raw material blending process via considering chemical composition, feed flow fluctuation, and various craft and production constraints.

The heating that occurs in the kiln transforms the raw materials into new chemical compounds. Therefore, the chemical composition of the cement is defined by the mass percentages and composition of the raw sources of lime, iron, silica, and alumina as well as the temperature and duration of heating.

Fine ground raw meal is then stored and further homogenized in the raw meal silo. The heart of the cement manufacturing process is the thermal process in the kiln system with clinker capacities of up to 12,000 tonnes per day nowadays. A kiln system consists of a static preheating system with typically five cyclone stages and a pre-calciner.
