  • White Cement Manufacturing Industry. How to Start a Cement

    White cement is produced from non-iron containing raw materials such as China clay and white limestone as well as with materials containing a low content of coloring elements such as Fe, Mn, Cr, and Ti. Moreover, white cement is manufactured in a separate kiln and is therefore more expensive than standard Portland cement.

    White ordinary Portland cement should confirm to IS: 8042-1989. Manufacturing of white cement The manufacturing process of white cement is somewhat different from manufacturing process of gray cement. During manufacturing if metal oxides i.e. iron and manganese are added, they help in increasing the whiteness of cement.

    However, this modification in its production method makes White Cement far more expensive then the ordinary cement. The production of White Cement requires exact standards and so it is a product which is used for specialized purposes. White Cement is produced at temperatures that hover around 1450-1500 degrees Celsius. This temperature is more than what is required by the ordinary grey cement

    The cement production process, for example, starts with mining of limestone, which is then crushed and ground to powder. It is then preheated to save energy before being transferred to the kiln, the heart of the process. The kiln is then heated to a high temperature of up to 1480 degrees to convert the material to a molten form called clinker. The clinker is then cooled and ground to a fine powder with

    The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore. Since limestone is the main component, often cement plants are located near limestone quarries. The first step in both manufacturing processes after quarrying is primary crushing. Next, the raw materials are combined in the correct amounts and fed into the kiln system. In the kiln, the initial raw ingredients
