Cement contains multiple ingredients as its raw material like lime, silica, alumina, iron oxide etc. These ingredients interact with one another in the kiln during the manufacturing process and make a complex compound (Cement). The concrete or mortar should be recognized as best, if the chemical composition of the cement is well proportioned.
Example Let us consider an example of a simple and typical batch manufacturing process of raw material preparation for making fiber–cement sheets. A typical fiber–cement manufacturing plant consists of three process cells, namely (i) raw material batch preparation, (ii) sheet formation and (iii) sheets sizing, handling and curing.
The raw material preparation stage of cement manufacture results in the production of a rawmix that is in a suitable state for feeding to the kiln in which it is converted by heat into clinker. This is a chemical transformation. The rawmix consists of a mixture of materials that will react together to form the calcium silicates that confer on ...

Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.
Our OK Mill grinding solution skilfully comminutes raw material, cement and slag. You can easily adjust it to grind any feed material and produce multiple cement types in the same mill. Due to its highly effective drying performance, the OK Mill is the natural choice for grinding blended cements with one or more wet components.
Cement, as a binding material, is a very important building material. Almost every construction work requires cement. Therefore, the composition of cement is a matter of great interest to engineers. For understanding cement composition, one must know the functionality of Cement ingredients.
Raw materials used for manufacturing of Portland cement are found naturally in the earth''s crust. It is made primarily from calcareous and argillaceous materials and gypsum. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silicaalumina and iron. Both are found as clay or shale.
