Abstract: An installation for quick thermal treatment of suspended powder substances, in particular for flash calcining of mineral substances, comprises modules advantageously arranged in mobile units including elements for supplying powder substances, a combustion chamber wherein the substances are introduced suspended in a hot air flux and a cooling assembly where the calcined substances are recuperated to pre-heat the combustion air. The substances are pneumatically transported in the heated air downstream of the supplying elements, via a pre-heating device up to the combustion chamber.
