Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and is of predominantly fine grained crystalline structure, its hardness is between to of the Mohs scale of hardness and specific gravity 2. To Limestone usually contains admixtures of clay substance or iron compounds, .
Raw mill 4 materials 225tph limestone 88%, sandstone 5%, kaolin/clay 5%, mill scale 2% 2. Raw materials are ground to powder and blended. Or 2. Raw materials are ground, mixed with water to form slurry, and blended. Kiln 3. Burning changes raw mix chemically into cement clinker. REACTIONS IN THE KILN • ~100°C→ free water evaporates.
Generally cement plants are fixed where the quarry of limestone is near bye. This saves the extra fuel cost and makes cement somehow economical. Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing.
At cement plant, according to different raw materials preparation methods, cement manufacturing can be divided into the dry process (including semidry process) and wet process (including semiwet process). Next, we will discuss the wet process of cement manufacturing .

Raw materials for the production of cement. Minerals of natural origin as well as industrial products can be used for the production of cement. Starting material for this purpose are mineral compounds containing the main components of cement: lime, silica, alumina and ironoxide. Seldom are these components present in the needed proportion in ...
The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km. The limestone is excavated from open cast mines after drilling and blasting and loaded onto dumpers ...
