Abstract

1536849 Forming granules in fluidised beds CHARBONNAGES DE FRANCE 4 Aug 1976 [18 Aug 1975] 34285/75 Heading B1F [Also in Division B5] Granules, e.g. of pitch or bitumen, are formed by solidification of drops of liquid phase introduced onto a fluidised part of a cooled pulverulent solid e.g. silica, situated above a perforated grid 2, Fig. 2, there being a non-fluidised part situated above an imperforate metal plate 4, inclined vibrations being applied to the bed by vibrator 8 so that the forming granules are circulated e.g. as shown by arrow 11 in Fig. 1 so that they pass up screens 9, particulate material passing through the screens back to the bed, and granules being discharged at the end of the screens. Cooling may be effected by cooling tubes, by evaporation of water introduced into the fluidising gas or directly into the bed, or by recycling part of the cooled product.
