Extraction
In this method of producing white cement, raw materials such as limestone, kaolin and gypsum are extracted from the mine and transported to the factory to be stored in the silo.

Crushing and grinding stage
In this stage of white cement production, first the stones enter the stone crusher and are crushed with certain proportions, then the materials are taken to the sampling area and after removing the defects, the materials are transferred to the machine that combines them with a conveyor belt. They transfer After going through this stage of white cement production, they grind the materials so that the materials they crushed and combined turn into powder.

cooking stage
In this part of white cement production, raw materials are baked in special ovens, then some of the remaining raw materials and a small amount of materials are lost.

Final level
In the final stage of white cement production, raw materials and clinker are combined with gypsum and are turned into white powder by the mill, which is called white cement, then they are transferred to the storage silo and packed.

The degree of whiteness of white cement
The most important property of white cement is its whiteness. This grade is determined using rigorous tests; In fact, the degree of whiteness of white cement is determined using a D65 light source and also using the Hunter method. In this way, the white color should completely reflect the red, green and blue colors. to have On the contrary, black color should not have any reflection towards these three colors. The amount of light reflection is compared with the standard whiteness considered for this material, and based on that, the degree of whiteness of white cement is determined.
