cements whose production volumes are considerably lower compared to those of conventional cements (max. 5 to 10 %). However, they constitute a significant part ... the sintering process and to facilitate the firing with ... manufacture of white cement clinker, as the method may also be …
During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the "setting of cement".
White Portland cement or white ordinary Portland cement (WOPC) is similar to ordinary, gray Portland cement in all aspects except for its high degree of whiteness. Obtaining this color requires substantial modification to the method of manufacture, and because of this, it is somewhat more expensive than the gray product.
Manufacturing Process of White Cement. The difference in the manufacturing process is mainly responsible for the difference in the color of the cement.White Portland cement has been manufactured with different raw materials. Due to the presence of metal oxides, like iron and manganese, the color of this type of cement turns white.
This 6 week online training course will be suitable for employees of white cement manufacturing companies, those who are considering manufacturing white cement, and employees of companies supplying equipment, goods and services to white cement manufacturers.
The manufacturing process of white cement should be controlled with special precautions. The white cement manufacturing process is more or less similar to its grey OPC counterpart, except for the change in raw mix or materials, clinker quenching.
Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.
The next development in the manufacture of Portland cement was the introduction of the rotary kiln, which produced a stronger, more homogeneous mixture and facilitated a continuous manufacturing process.

In the conventional white cement manufacturing process the exhaust gases at raw mill, kiln and cooler (decoloriser/ dryer) are discharged in to atmosphere through Electrostatic precipitators (ESP) /Bag House. Figure 2 illustrates a white cement manufacturing plant at operating condition.
White Cement Manufacturing Industry. How to Start a Cement Manufacturing Factory? Cement Industry Poised for Faster Growth. White cement, as the name indicates, is a kind of cement with white color. White cement is similar to ordinary, gray Portland cement in all aspects except for its high degree of whiteness.
The resulting cement slurry flows into storage tanks. Must Read: Dry Process For Manufacturing of Cement When lime stone is used, first blast it, then crushed in two progressively smaller crushers and then fed into a ball mill with the clay dispersed in water.
ARTICLES / Cement Based Tile Adhesive Formulations | Manufacturing Process Cement based and white tile adhesive contains white cement, silica sand using for filler,talc using for filler,calcite using for filler, starch ether using for holding water, methyl cellulose or hydroxyethyl cellulose using for thickness of mixture and etc.
In principle, any type of kiln used for grey clinker production can also be used for white. Internationally, wet, long dry, Lepol, suspension preheater and precalciner kilns are used for white production. Although the process is in general the same as for grey clinker, there are certain distinctive features.

The invention provides a process for manufacturing white cement which includes steps of recovering flue gases generated during the quenching and drying process, extracting heat from the recovered flue gases to obtain water condensate and to generate electrical energy.
The manufacturing process of white cement is same as that of grey cement, but the selection of raw material is an important part in the manufacturing process. The oxides of chromium, manganese, iron, copper, vanadium, nickel and titanium imparts the grey colour to the cement.
White Cement is an ordinary Portland Cement in which iron & manganese oxides are added to increase whiteness of cement during manufacturing. Now a days lot of colored cements are available in market which can be manufactured by adding color pigments.
Other main features of White Portland Cement are given below: The color of cement is an especially important issue in the white cement. Therefore, the principal concerns are consistency in brightness and tone. The quality of raw materials and the manufacturing process affects the color of the white cement.
Manufacturing Portland Cement. The basic ingredients of both the dry and wet processes are the same. By mass, lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.
