| 摘要 |
<p>The invention concerns a method and a device for heat treatment of finely divided solids, which consist in organising a gradual and continuous unidirectional displacement of solid particles along a vibro fluidised bed, and in subjecting said particles to a heat treatment at medium or high temperature while they are being displaced. The invention is characterised in that the heat treatment is performed by heating from the outside the conveying tube (10), and the solid particles are displaced under controlled atmosphere in said heated tube (10) up to a hot centrifuge (20) so as to avoid condensation of the condensable gas fractions, with vapour and gas evacuation, and recuperating the solid residues.</p> |
