Abstract

1381480 Fluidised bed spray dryer STRUTHERS SCIENTIFIC &. INTERNATIONAL CORP 9 June 1972 [18 June 1971] 28753/71 Heading B1B [Also in Division F4] In a fluidised bed spray dryer 5, product granules are sifted in separator 22, and oversize granules are pulverized at 26 and recycled to the dryer. Granules of ammonium sulphate, ferrous sulphate, or ammonium sulphate may thus be produced.
