Abstract

1340302 Cooling granular material SNIA VISCOSA SOC NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA 1 Feb 1972 [4 Feb 1971] 4557/72 Addition to 1214345 Heading F4U Apparatus for cooling granular material according to Specification 1,214,345 is modified by the baffle positioned directly behind the inlet to the drum is to remove kinetic energy from pneumatically conveyed granules flowing into the drum, the lifting and dropping means within the drum extend substantially the whole length of the drum, and an outlet is of diminishing cross-sectional area in order to re-accelerate the gas stream which outlet is formed by ducts. In a modification, a further drum 110 having lifter blades 130 is spacedly and coaxially positioned within the drum 10. Both the outer surface of the drum 10 and inner surface of the drum 110 are cooled by water which is sprayed on to the top of the outer drum and allowed to flow through tubular passages 125 into the inner drum and subsequently discharged to the outside of the outer drum.
