| description | The invention concerns a process and an installation for dehydroxylation treatment of aluminium silicate, in which particles containing aluminium silicate are exposed to a temperature of at least 500° C. The particles are in the form of a dry powder, and the dry powder (26) is optionally transported in a gas stream (30) at a temperature of from 600 to 850° C., for a time which is sufficient to achieve the desired degree of dehydroxylation. The powder may be obtained from a hydrated base paste by reducing the base paste into fragments (23), and by disaggregating the fragments (23) of base paste by mechanical action (at 3) in the presence of a hot gas (24) at a temperature of from 500° C. to 800° C., in order to form the dry powder (26). |
