Abstract

L'installation comporte un silo de stockage (10), un silo de distribution (30), une série de doseurs (24A et 38) pour extraire les matières pulvérulentes du silo de distribution (30), des conduites de transport pneumatique (36) reliant chacun des doseurs à ladite enceinte, ainsi que des moyens pour transférer automatiquement la matière pulvérulente du silo de stockage (10) vers le silo de distribution (30).
Pour réduire la taille des silos et des conduites, on a prévu deux silos intermédiaires (24A, 24B) reliés chacun à travers des vannes automatiques (22, 28), en amont, au silo de stockage (10) et, en aval, au silo de distribution (30) et un circuit de pressuri­ sation reliant une source de gaz inerte sous pression à travers des vannes automatiques (50A, 50B) à chacun des silos intermédiaires (24A, 24B).
