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.
