Cement raw materials grinding: most of cement raw materials should be ground in the cement mill, and the grinding body can't contain iron. As for the fineness, the white cement manufacturing process requires a finer size than that of Portland cement.
Ordinary Portland cement, the most widely used standard variety, is made by grinding up limestone and then cooking it with sand and clay at high heat, which is produced by burning coal. The process produces carbon dioxide in two different ways: from the burning of the coal, and from gases released from the limestone during the heating.
White Portland 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.
Cement production is a highly energy-intensive manufacturing process with energy consumption of 85-100kWh/t of cement – most of which is used by grinding operations. This high level of energy consumption, along with increasing cement demand and CO 2 emissions, requires the use of efficient grinding technologies such as vertical roller mills ...
The production process consists of grinding the raw materials to a fine stage, blending them to a uniform composition and heating them to the point of incipient fusion when the cement compounds are formed. The white Portland cement is the product obtained by cooling and grinding the clinker thus formed with gypsum to a fine powder.
JK White Cement Works, Gotan. The first White Cement facility in India, which was limestone-based, and manufactured Cement through the dry process. The White Cement plant was commissioned in 1984 at Gotan, Rajasthan, with an initial production capacity of 50,000 tons.
The production process of white Portland cement is quite different from ordinary Portland cement. It is unique in both process flow and cement equipment selection. In white …
The cement industry is particularly reliant upon particle size reduction. Raw materials crushing and grinding seeks to reduce materials from roughly one meter cubes of blasted stone to a size where at least 80 percent of the raw material is less than 75 microns. Finish grinding of clinker and other cement
Ball Mill. We bring forth a highly advanced Ball Mill, specifically engineered for both wet as well as dry cement grinding applications. Classified depending on the circuit design, bearing, grinding type and drive, the selection is made on the basis of the product fineness, quality, and nature of raw material, site conditions and specific requirements.
Cement grinding plant is the last station in the cement production line. Its power consumption accounts for 65% – 75% of the whole cement plant. Therefore, reducing the energy consumption in the cement grinding process is of great significance for energy conservation and emission reduction of the cement manufacturing plant.

Ivory Coast: LafargeHolcim Côte d'Ivoire has announced plans for the launch of white cement production at its Abidjan grinding plant in 2022. APA News has reported that the plant's clinker costs increased by 80% quarter-on-quarter in the third quarter of 2021. This, along with a drop in grey cement prices, inspired the strategic change.
White Portland cement is also used in combination with inorganic pigments to produce brightly colored concretes and mortars. Ordinary cement, when used with pigments, produces colors that may be attractive, but are somewhat dull. With white cement, bright reds, yellows and greens can be readily produced. Blue concrete can also be made, at some ...
Answer (1 of 2): White cement is very prone to cracks when it dries. It defers from ordinary grey cement. It is fine grind cement. It starts hydration quickly and generate heat that causes it dry up quickly and forms cracks. To prevent cracking do not use only white cement. Add marble dust 25% an...
