Abstract

1343433 Cellular cement C G BEVAN ASSOCIATES Ltd 30 Dec 1970 [27 Jan 1970] 3979/70 Heading C1H [Also in Divisions B5 B1 and B8] In a hopper for powdered or particulate material wherein the material in the hopper is simultaneously subjected to fluidization and vibration, the outlet duct 17a is subject to vibration only to form a compaction zone for the discharged material and a screw or other mechanical means acts on said compacted material in a further zone 18 to control the rate of discharge of the material. By the use of suitably cooled air. material such as ice powder can be metered. Reference is made to the mixing and extrusion of a mixture of cement powder and ice powder, the ice being melted by heating to produce a stabilized product.
