— Cement Manufacturing Process. Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
The clinker manufacturing process The preheating of the material takes place in pre-heater cyclones fitted with a pre-calciner fired with petroleum, natural gas or coal. The calcinations of the material begin during this stage, changing its phase to the oxide phase for each component to be ready for the burning process.
— The manufacturing of cement at our Plant involves the selection of best quality raw materials and employing the Dry Process; major portion of ingredients consists of Limestone and Clay. The raw materials are quarried, crushed and corrected for subsequent mixing to form Raw Mix, which is then grinded in Raw Mill and subsequently …
Burning: In this operation, the slurry is directly fed into a long inclined steel cylinder called a Rotary kiln.In this kiln there are 3 different zones shown in fig. below. Cement Manufacturing Process Flow Chart (i) Drying Zones: In the wet process, the drying zone is comparatively larger than the dry process. It is because the raw material in slurry form is …
