Flash calcination of kaolinite rich clay and impact of

Flash calcination tests of the kaolinite rich clay particles are also performed in a pilot-scale gas suspension calciner. The model is validated by the experimental data (e.g., the degree of dehydroxylation and the density of the calcines). Based on the model, the impacts of process conditions and feed properties on the quality of the

Kiln vs flash calciner FLSmidth

Q: What is the process involved in flash calcination? TK: For customers dealing specifically with fine ores, we designed the Gas Suspension Calciner (GSC) technology something we have supplied since the beginning of the 1970s. It consists of a series of preheating cyclones, a calciner vessel and a series of cooling cyclones.

The use of flash calcined dredging sediments in

1992 [21]. The flash calcination technique was originally applied to chemically activate some clays such as Kaolinite and to confer pozzolanic properties. When applying this technique to Kaolin clays, a dehydroxylation process following the dehydration was noted [20,32]. This fits with the elimination of a hydroxyl bond (−OH) which occurs
