كواحد من قادة calcination kaolin process الصناعة ، تسعى SBM دائمًا إلى الابتكار والتميز.
The main process important for production high reactivity pozzolana from kaolin clay is calcination. The heating process drives off water from the mineral kaolinite (Al 2 O 3·2SiO 2 ·2H 2 O), the main constituent of kaolin clay, and collapses the material structure, resulting in an amorphous aluminosilicate (Al 2 O 3·2SiO 2), metakaolinite.

Calcination Process. Using extremely high temperatures reaching 1400 ˚C in 92m long rotary kiln to remove some unwanted elements and to alter the properties of minerals, the calcination of kaolin generally increases hardness and alters the electrical properties of the material. The process also leaves the Kaolin anhydrous (without water).
