PCT No. PCT/EP83/00247 Sec. 371 Date May 18, 1984 Sec. 102(e) Date May 18, 1984 PCT Filed Sep. 21, 1983 PCT Pub. No. WO84/01113 PCT Pub. Date Mar. 29, 1984.A plunger pipe (40) connectable to a gas source projects axially from above into a container (10) which is rotationally symmetrical with respect to a vertical container axis (A). A dish (16) is arranged below the plunger pipe (40) to deflect the gas supplied through the plunger pipe (40) in upward direction so as to move the material (C) contained in the container (10). In an upper area of the container (10) a deflector shield (56) is arranged around the plunger pipe to deflect the material (C) entrained upwardly by the gas in outward direction. A gas outlet opening (26) is disposed above the deflector shield (56) which is permeable to gas at least in some areas. The apparatus is suitable for mixing, drying, granulating, pelleting, polishing, and/or coating pulverous or granular material. |
