Abstract
Light granular material is manufactured from silico-aluminous material by crushing and/or screening the silico-aluminous material to a fine powder which is mixed with water to form a slip which is divided into drops which are immediately introduced into a hot fluidised bed. The water evaporates rapidly and the drops are converted into expanded granules which are recovered and subjected to ceramic firing.
