Eﬀect of primary particle size on spray formation, morphology and internal structure of alumina granules and elucidation of ﬂowability and compaction behaviour

Three diﬀerent alumina powders with varying particle sizes were subjected to spray drying under identical conditions and eﬀect of particle size on heat transfer eﬃciency and mechanism of formation of granules was elucidated. Morphology, internal structure and size distribution of granules were studi...
