FIELD: metallurgy.SUBSTANCE: pneumatic pipe-dryer includes a vertical cylindrical pneumatic pipe ending with an unloading device, and material supply device. Pneumatic pipe consists of sections, the lower section of which is connected to ambient air source (fan) and feeder, and the middle one, which is separated from lower and upper sections (or only from lower section) with inserts from heat insulating material, is made in the form of two coaxially located shells, the inner shell of which is provided with holes, and the space between shells - a spiral channel is filled with heat carrier through a tangentially located connection pipe.EFFECT: avoiding the problem of material sticking on inner surface of pneumatic pipe.3 cl, 1 dwg |
