Flash calcination of clay - IMT Mines Albi

When used for flash calcination (a matter of seconds), the model gave results which we compared with experimental values from a oratory flash calciner built for the purpose, and from an existing pilot. Mineralogical and structural properties of flash calcined products have been studied; two lime reactivity tests enable us to assess the

A study on flash calcination of kaolinite rich clay particles in a gas suspension calciner is presented. The impacts of calcination temperature on the properties of the clay calcines are experimentally investigated. Within a residence time of 0.5 s, moderate temperatures of about 950 °C are likely to be the most appropriate condition to

Flash calcination of kaolinite rich clay and impact of

15/01/2016  Process conditions during clay calcination significantly affect the quality and pozzolanic reactivity of the calcines. For instance, flash calcination is found to produce metakaolin with better pozzolanic reactivity than soak calcination does . There is a lack of modeling effort on flash calcination of kaolinite rich clays.

NOTES PROPERTIES OF FLASH-CALCINED KAOLINITE

This clay, which is designed for the paint industry, has a brightness of approximately 89.0. The density and bound water content were measured as 2.60 g/cm 3 and 12.4%, respectively. Flash calcination was carried out in a resistance- heated, laminar-flow furnace in a helium atmosphere.
