The Effect of Calcination Temperature on Metakaolin

The effect of Metakaolinization on the thermal and physicochemical properties of Badau Belitung kaolin is presented. Calcination of Badau Belitung kaolin indicated that kaolin was transformed to metakaolin at temperature above 500C. The metakaolin was characterized using Xray Diffraction (XRD), Fourier Transform Infrared (FTIR) and BrunauerEmmettTeller (BET).

Effect of calcination temperature on activation behaviors

Calcined kaolin eliminated activity ascribed to the recrystallization into mullite when calcination temperature was over 1000 C. It was believed that fluidized bed calcination was an efficient thermal activation technology for coalseries kaolin and the calcination

white minerals

Jul 17, 2012The process of producing calcined kaolin from kaolin is carried out in either conventional calcination method or flash calcination techniques. Calcined kaolin, or popularly referred as calcined clay, is an anhydrous aluminium silicate with enhanced whiteness, hardness, electrical properties and kaolin particle structure.

Sustainability

Three metakaolins are evaluated for use as supplementary cementitious materials in cementbased systems. The metakaolins vary in mineralogical composition and in fabrication (traditional and flash calcination), but are quite similar in their surface area (16–19 m2/g), but are quite similar in mineralogical composition. Performance of metakaolin mixtures will be compared to two control

This Bureau of Mines report describes calcination of kaolinitic clay in a directfired 2 1/2 by 24ft rotary kiln at 750 deg and 775 deg c. Methods for preparing kaolin feed materials and characterization of calcined products are discussed. Approximately 99 pct of the alumina in a typical eastern Georgia kaolin was soluble in hcl after calcination at either 750 deg or 775 deg c.

Dynamic modeling of a multiple hearth furnace for kaolin

Nov 01, 2015A dynamic model of a multiple hearth kaolin calciner has been developed and is presented in this article. This model describes the physical‐chemical phenomena taking place in the six furnace parts: the solid phase, gas phase, walls, cooling air, rabble arms, and the central shaft. The solid phase movement, in particular, is described by a novel mixing model. The mixing model divides the
