UN APARATO PARA PRODUCIR CLINKER DE CEMENTO BLANCO (COMO DIVISIONAL DE LA SOLICITUD DE PATENTE DE INVENCION NUM. 544.021, PRESENTADA EL 10.06.1985)

摘要

The apparatus includes a fluidized bed furnace (1) communicating via an injection pipe (3) with the top of a reduction chamber (2) which in turn communicates with a primary cooling chamber (4) which communicates with a secondary cooling chamber (6). In use, raw materials in powder form are fed into the furnace (1) in which there is a fluidized bed and clinker particles are formed. Reducing gas flows through the pipe (3) into the furnace and when the clinker particles have reached a predetermined size they fall down into the reduction chamber (2) and are reduced. The clinker particles are then fed into the chamber (4) where they are cooled to between 600 and 700 DEG C by spraying with water. The particles are thereafter fed by feed means (7) into the secondary cooling chamber (6) in which they are cooled with air.
